the underwent a fuel element failure, with the emission of gaseous fission products into the surrounding air. This resulted in 9 crew fatalities and 83 injuries. Development and early opposition to nuclear power The total global installed nuclear capacity initially rose relatively quickly, rising from less than 1 gigawatt (GW) in 1960 to 100 GW in the late 1970s, and 300 GW in the late 1980s. Since the late 1980s worldwide capacity has risen much more slowly, reaching 366 GW in 2005. Between around 1970 and 1990, more than 50 GW of capacity was under construction (peaking at over 150 GW in the late 1970s and early 1980s)—in 2005, around 25 GW of new capacity was planned. More than two-thirds of all nuclear plants ordered after January 1970 were eventually cancelled. A total of 63 nuclear units were canceled in the United States between 1975 and 1980. In 1972 Alvin Weinberg, co-inventor of the light water reactor design (the most common nuclear reactors today) was fired from his job at Oak Ridge National Laboratory by the Nixon administration, "at least in part" over his raising of concerns about the safety and wisdom of ever larger scaling-up of his design, especially above a power rating of ~500 MWe, as in a loss of coolant accident scenario, the decay heat generated from such large compact solid-fuel cores was thought to be beyond the capabilities of passive/natural convection cooling to prevent a rapid fuel rod melt-down and resulting in then, potential far reaching fission product pluming. While considering the LWR, well suited at sea for the submarine and naval fleet, Weinberg did not show complete support for its use by utilities on land at the power output that they were interested in for supply scale reasons, and would request for a greater share of AEC research funding to evolve his team's demonstrated, Molten-Salt Reactor Experiment, a design with greater inherent safety in this scenario and with that an envisioned greater economic growth potential in the market of large-scale civilian electricity generation. Similar to the earlier BORAX reactor safety experiments, conducted by Argonne National Laboratory, in 1976 Idaho National Laboratory began a test program focused on LWR reactors under various accident scenarios, with the aim of understanding the event progression and mitigating steps necessary to respond to a failure of one or more of the disparate systems, with much of the redundant back-up safety
