Bombs are not the only form of nuclear terrorism. In the United States, there are over 60 nuclear power plants in operation. Henry Sokolski, the executive director of the Nonproliferation Policy Education Center, fears that people with destructive intentions could attempt to unleash the power of the nuclear energy system. He says that "the purchase or theft of nuclear materials from Iran, North Korea, or other rogue states . . . is less likely than possible attacks against nuclear facilities".  While the construction of a functional nuclear weapon requires obscure resources, high-level expertise, and sophisticated technology, disturbing a nuclear power plant has a much lower barrier. Reliance on nuclear energy could pose a risk to national security. (Fee Fig. 1.)
Japan's Fukushima Daiichi disaster demonstrates that the consequences of nuclear fallout may outweigh the economic advantages of atomic energy. When things are going according to plan, nuclear energy provides a tremendous amount of economic value. According to the Nuclear Energy Institute, a nuclear plant can generate around $470 million in net value each year.  However, this figure is nothing compared to the damage that can be done by a nuclear plant. The Fukushima Daiichi incident had a devastating impact on Japan's economy. After accounting for damages, and the cleanup of radioactive waste (Fig. 1), Japan had to spend an estimated $188 billion.  A single unfortunate incident can wipe away all the value a nuclear plant can provide.
Many experts fear that terrorists could breach the security of nuclear reactors.  Sokolski suggests that many active nuclear power plants have weak points, which include but are not limited to their spent fuel pools, their electricity supplies, and their pressure vessel containment domes.  He refers to a 1982 study, which found that "if a jet aircraft crashed into a nuclear reactor and only 1% of its fuel ignited after impact, the resulting explosion could compromise the integrity of the containment building, with possible release of radioactive material".  This analysis aligns with the perspective of nuclear safety expert John Large, who suggests that "You don't need massive amounts of force to allow a nuclear plant to go into instability. The plant has enough energy to destroy itself". 
Nuclear power plants are also susceptible to cyber terrorism. There are a variety of historical precedents for software being used to threaten nuclear reactors. In 2010, Iran identified a computer virus that was impacting the operations its Natanz nuclear facilities.  This virus, now known as Stuxnet, is believed to have destroyed an upwards of 1000 nuclear centrifuges.  The Stuxnet incident made it clear that the security of nuclear systems is an unsolved problem. In 2014, another cyber attack occurred at a South Korean nuclear facility. While no reactors were directly influenced and no critical data was obtained by the hackers, this circumstance sent an eerie message. Suh Kune-yull of Seoul National University says the event "demonstrated that, if anyone is intent with malice to infiltrate the system, it would be impossible to say with confidence that such an effort would be blocked completely".  The fact that the integrity of such powerful systems can be jeopardized by malicious software brings the future of nuclear energy into question.
