A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles.

The temperature in the core will exceed 5,000°F (2,760°C), causing hundreds of uranium fuel rods to slump to the bottom of the containment vessel like melted wax. The fuel will burn through the foundation of the plant, sinking into the ground and contaminating the water table. Pressure in the cores will climb high enough that the vaultlike vessels will no longer be able to withstand it. Before long they will erupt in a radioactive cataclysm, spreading a deadly, carcinogenic cloud across Japan and — depending on the whims of the wind — around the world. Here’s the much-better-case scenario: those same workers will soon get ahead of the heating curve, adding cool seawater to the reactors at the same time as the fuel rods’ natural decay causes them to lose heat by themselves. Some people exposed to radiation will get sick; some workers may die. The radioactive plumes will dissipate; the plant will be shut down; the evacuees will go home. You don’t need to stock up on iodine pills or canned goods or batteries. [(See photos of Japan’s immense devastation.)](http://lightbox.time.com/2011/03/14/amid-japans-devastation/#1) It’s still too early to say whether the bright yin or the dark yang will be closer to how the Fukushima drama unfolds, and true clarity may not come for a long time yet. What is certain is that whatever happens, we all need to start thinking very hard about how we got into this mess and how we can prevent it from ever happening again. Death by radiation has always been humanity’s great self-inflicted wound. Nature may have cooked up the unstable elements that contain and emit radioactive energy, but it also took care to hide the stuff away — burying it in mountains, sealing it in planetary cores. Humans had to work very hard to pick that natural lock. It wasn’t until the past seven decades that we understood the elemental energy of radioactive rocks well enough to distill it into pellets, rods and lumps and, in our first demonstration of our newfound power, use it to incinerate two Japanese cities at the end of World War II. [(Watch a four-minute explanation of Japan’s nuclear crisis.)](http://www.time.com/time/video/player/0,32068,833602970001%5F2059584,00.html) Japan is suffering once more, and we are again left to examine the wisdom of having ever let the radioactive genie out of the bottle — and at just the time that nuclear power had been experiencing a bit of public redemption. As the world struggles with the realities of climate change and the political and fiscal costs of our dependency on fossil fuels, many have accepted that nuclear power must be part of any sensible energy mix. But that was before Fukushima; before the rolling explosions of nuclear-reactor containment buildings; before the ever-expanding danger zone, which started at 3 km (1.9 miles) and by March 15 stood at 30 km (18.6 miles); before tens of thousands of people were displaced and 140,000 more were urged to stay sealed inside their homes. When a government official like Chief Cabinet Secretary Yukio Edano starts speaking gobbledygook like “At this point we can say we are moving in the direction of stabilizing the situation in a certain managed manner,” you can be pretty sure he’s not stabilizing anything. And when what’s not being stabilized is radioactivity, even the wisest heads start to get spooked. “This is extremely scary,” says physicist Kenneth Bergeron, a former research scientist for Sandia National Laboratories in Albuquerque, N.M., who specialized in reactor accidents. “It was not at all inevitable that it had to play out like this.” **Rewriting the Book** The known unknowns keep piling up at Fukushima — the number of people who will die of radiation poisoning, where the wind will carry the radioactive plumes. At the most personal level, we don’t know how to count up our exposure to stray radiation or how the residue from Fukushima that may invade our bodies uninvited compares with the amount we admit willingly from an X-ray or even a day at the beach. “This is rewriting the book on nuclear accidents,” says physicist Arjun Makhijani, president of the Institute for Energy and Environmental Research in Takoma Park, Md. “It’s a combination of earthquake and tsunami causing a lot of damage that’s emerging only over the course of days.” The crisis at the Daiichi plant is principally a result of flooding, which inundated emergency power systems and made it impossible to pump needed cooling water to the fuel rods in the reactors. Paradoxically, too much water where they didn’t want it resulted in too little where they did. So why didn’t the Japanese prepare? [(See the scary health dangers of radiation exposure.)](http://www.time.com/time/video/player/0,32068,833974025001%5F2059804,00.html) Actually, they did. About 40% of Japan’s coastline is protected by seawalls, but near Fukushima, the 33 ft. (10 m) tsunami — a very big one — easily overtopped them. Still, simply because the region flooded didn’t mean the diesel-powered generators had to be swamped. Situating them above the waterline could have kept them running. But since the designers assumed the seawall would be sufficient, they put the diesels on the ground floor of the plant. The quake caused grid power to be lost, and within an hour, the generators sputtered to a stop too. “The plant was supposed to have redundant systems to prevent this,” says Bergeron. “But if you have four diesels on site and they can all be wiped out at once, that’s not real redundancy.” A power-plant blackout is something safety experts train hardest for — and dread the most — because even the best nuclear reactors operate on a thermal knife edge. Each of the six reactors at the Daiichi plant consists of 400 to 760 fuel rods about 14 ft. (4.3 m) in length. They are housed inside a bell jar — like steel and concrete containment vessel, which is protected by a larger, bunkerlike building. Even with coolant constantly bathing the fuel rods, the temperature inside the vessels stays above 500°F (260°C). When the diesels died, the coolant pumps quit. In less than a day, the temperature rose above 2,200°F (1,200°C). That caused the vessels to vent hydrogen, which filled the buildings and led to their sequential explosions: Reactor 1 the day after the quake, Reactor 3 two days later, Reactor 2 the day after that. Reactors 4, 5 and 6 were offline when the quake hit. They needed water too, but since they were cooler to start with, they seemed to present no immediate problem. [(See photos inside the embattled Fukushima plant.)](http://www.time.com/time/photogallery/0,29307,2058823,00.html) Despite all this, Fukushima is no Chernobyl — at least not yet. Chernobyl had no containment vessels, which means that once the external building blew, the radioactive plume blasted out everywhere. What’s more, the Chernobyl plant was also used to process plutonium for weapons, making it more susceptible to what nuclear engineers call “neutronic excursion” and what other people call “explosions.” Finally, in the moments preceding the Chernobyl accident, operators were, ironically, testing a new safety protocol that spun out of control. “Basically,” says Bergeron straightforwardly, “you had idiots running the plant.” But within three days of the quake, the Japanese were starting to look less than brilliant themselves — as was General Electric, the American vendor that designed the Daiichi reactors. The Mark 1, the GE model that was popular in 1971, when the plant went into service, has been criticized for having less robust containment vessels than other plants of that era. That may be so, but its more immediate shortcoming is a design feature it shares with other older reactors. In all those systems, spent fuel rods are stored in a pool inside the concrete reactor building for at least 10 years before being transferred to long-term storage. As long as water circulates constantly, the pools remain stable. But when power is lost, the circulation stops. And when the roof blows off, the pools are exposed to the air. Add the heat generated by the rods, and the water starts to boil away. “If you don’t cool the spent fuel, there may be a swift chain reaction that leads to spontaneous combustion, an explosion and fire,” says research scientist Ferenc Dalnoki-Veress of the James Martin Center for Nonproliferation Studies in Monterey, Calif. [Read “Is Japan’s Bureaucracy Strangling Aid Efforts?”)](http://www.time.com/time/world/article/0,8599,2060773,00.html) A fire just like that began on March 15, but to the surprise of engineers, it started in Reactor 4, which had not been in operation. The fire crept up quietly because the cooling pool is 45 ft. (14 m) deep but the rods were stored in the bottom 15 ft. (4.8 m), meaning 30 ft. (9.6 m) of water had to bubble away first. The building remained intact as the fire raged, but the radioactivity spewing from it was what led to the last expansion of the danger that same day. Emergency workers were able to extinguish the blaze, but the alarm prompted Prime Minister Naoto Kan to take to the airwaves and appeal for calm while admitting there was “a further risk of more radioactive material coming out.” There was still more bad news. Engineers concluded that the explosions of the reactor buildings breached the containment vessels in Reactors 1 and 3, as well as the torus — an enclosed doughnut of water around the base of the vessel — in Reactor 2\. Not good. “If the primary containment vessel is leaking, then a core meltdown could lead to a very high release of radioactivity into the environment,” says physicist David Wright, co-director of the U.S.-based Union of Concerned Scientists. [(See the world’s 10 deadliest earthquakes.)](http://www.time.com/time/specials/packages/article/0,28804,1953425%5F1953424,00.html) Too Much for Comfort Meltdowns, in the sense of overheated fuel starting to soften and sink, are almost certainly under way in all three of the previously active reactors. The 50 workers left at the plant — who on March 16 were joined by 130 more — are fighting to prevent things from getting worse by pumping seawater mixed with boron through fire hoses into release valves in the containment vessels. Boron helps absorb neutrons, reducing radioactivity, and the seawater performs the cooling. The race is to bring the temperature under control before the fuel simply pools on the vessel’s floor, reducing the surface area that can be reached by the water. That would make it impossible to lower the temperature, which by then would be above 3,500°F (1,900°C). Ultimately, the fuel could simply burn through the floor and contaminate the ground and water table below. Rising heat and pressure could also cause the containment vessel to rupture. All that is still a possibility, but Bergeron sees some small cause for optimism. “They’ve had several days, and that’s certainly an advantage,” he says. “Every day is one more day in the decay curve of the heat. They start to need less and less water to do the cooling.” This small comfort is offset by the fact that as the reactors seem to pose a slightly smaller risk, the coolant-pool problem may be worsening. At a congressional hearing on March 16, Nuclear Regulatory Commission chairman Gregory Jaczko testified that he believes all the water in the Reactor 4 pool has boiled away. That would lead to massive gamma-radiation output. [(Why were Japan’s citizens unprepared for the nuke crisis?)](http://www.time.com/time/world/article/0,8599,2060873,00.html) “The dose rates are probably off the charts if the pool is drained,” says Robert Alvarez, a former senior policy adviser at the Department of Energy. “These pools have become the jokers in the deck.” All the more so because each of the Fukushima reactors — damaged or not — has one. In response to this latest development, the U.S. embassy recommended that Americans in the vicinity observe a 50-mile (80 km) evacuation zone. Alvarez would go further. “I’d get my butt on an airplane and get out of Japan,” he says. Even if the radiation is quickly contained, there’s already been too much for most people’s comfort. Radiation levels are measured in rems — for “roentgen equivalent man.” The average background exposure that most people absorb simply by living on earth is 2.4 millisieverts (mSv, or one-thousandth of a rem) per year. “It could account for some of the cases of cancer that appear in the general population that have no other evident causes, like smoking,” says Dr. Ira Helfand, a board member at Physicians for Social Responsibility. Medical procedures carry their own radiation load. A CT scan, for example, can expose you to about 10 mSv. In most cases, though, the benefits exceed the dangers. [See the perils faced by journalists covering the disaster.](http://www.time.com/time/world/article/0,8599,2060448,00.html) What harm any radiation causes depends on which elements are involved in the exposure. There are four kinds of isotopes that are the likeliest, from a public-health perspective, to be a danger if emitted by a nuclear power plant: iodine-131, cesium-137, strontium-90 and plutonium-239\. Exposure to iodine-131 can lead to cancer — specifically thyroid cancer — and it can happen comparatively fast. Epidemiologists estimate that after the Chernobyl explosion, there were 6,000 to 7,000 cases of thyroid cancer that would not otherwise have occurred. Strontium and cesium are not nearly so selective. “Strontium gets incorporated into bones and teeth,” says Helfand, “and can stay there, irradiating the body for a long time.” Strontium is most commonly linked to leukemia. Cesium behaves more like potassium when it’s inside the body, which means it circulates everywhere. It doesn’t linger as long as strontium does, but it stays long enough to cause cancer of the liver, kidneys, pancreas and more. Most toxic of all is plutonium, which is typically inhaled and likeliest to lead to lung cancer. [(See why the plutonium leakage might be the least of Japan’s nuclear problems.)](http://ecocentric.blogs.time.com/2011/03/28/fukushima-plutonium-escapes-but-thats-the-least-of-the-problems/) Not surprisingly, fears of such outcomes have led to overreaction. In the same way people stocked up on the antibiotic Cipro during the anthrax attacks of 2001, so they are now buying iodine pills. That’s indeed a hedge against thyroid cancer, since there is a limit to how much of any type of iodine the body can absorb. Filling up on the nonradioactive kind shuts out the kind a power plant emits. But taking iodine can be dangerous if you don’t know the right dose, and it’s just silly to bother until you have a real sense of what the danger is. Workers at the Fukushima plant, of course, are more at risk than the rest of us. On March 16, the radiation level between two reactor buildings was measured at 400 mSv per hour, a dose equivalent to undergoing 2,000 chest X-rays in the same period, according to the International Atomic Energy Agency. There have been no reports of what the levels have become if Coolant Pool 4 is indeed dry. The Japanese authorities are not revealing much about how they’re protecting the workers. They are surely wearing full bodysuits that protect them from particles and carrying dosimeters that let them know when they’ve reached a dangerous dose of radiation. The work is not a death sentence, but for some of them, it might be close. [(See how to stop a nuclear meltdown.)](http://www.time.com/time/world/article/0,8599,2058615,00.html) “The helicopter pilots who dumped sand on the burning core at Chernobyl knew they were going to die, and they did die,” says Shan Nair, a British nuclear-safety expert who was part of a panel that advised the European Commission on its response to that disaster. “We don’t know what the radiation levels are inside the plant. Reports of a 400-mSv figure suggest that it’s not a suicide mission, \[but\] it is still a risky operation.” Bergeron disagrees. “I think some of them will be sacrificed,” he says. “These are heroic actions, but it’s going to be a real challenge to keep some of these people alive.” As the fuel rods inside the ruined plant cool — assuming they do — tempers and panic will follow suit. It’s a hard truth that we have tied ourselves to nuclear power for years to come. In the short term, higher seawalls and more prudently placed diesels will help prevent a repeat of the current emergency. Future nuclear plants can include what are known as passive safety systems. Reactors could be immersed in water at all times, for example. In the event of an accident, the vessel could be opened to allow coolant to circulate on its own. The rub is cost. Passive controls and other modifications like sturdier design are expensive, and the only way the nuclear industry can compete with coal and oil is to not include too many bells and whistles — like extra safety systems — on reactors. One answer, of course, is to tax carbon, raising its cost to make alternatives such as wind and solar power competitive with fossil fuels, thus obviating the need for so much nuclear power. But that possibility brings the discussion full circle to an argument that seems to flare up every time there’s a Three Mile Island or a blown BP oil well or a group of 33 Chilean miners who get trapped underground. And it’s an argument we’ll keep having until the species that was clever enough to tame fire, harness steam and pry unthinkable power from a lump of uranium ore becomes smart enough to take the next step forward. _— with reporting by Eben Harrell / London, Bill Powell / Tokyo, Bryan Walsh / New York_ [See TIME’s complete coverage of the Japan earthquake.](http://time.com/japan) [See TIME’s 140 best Twitter feeds.](http://www.time.com/time/specials/packages/0,28757,2058946,00.html) ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6595474/fear-goes-nuclear/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6595474/fear-goes-nuclear/"},"headline":"Fear Goes Nuclear","datePublished":"2011-03-28T04:00:00.000Z","dateModified":"2026-02-25T06:16:39.817Z","description":"The crisis at Japan's crippled power plant has yet to play itself out.
