Nuclear reactor accidents in the United States ordered during the late 1960s raised new safety questions and created fears of a severe reactor accident that would send large quantities of radiation into the environment. In the early 1970s, a highly contentious debate over the performance of emergency core cooling systems in nuclear plants, designed to prevent a core meltdown that could lead to the "China syndrome", received coverage in the popular media and technical journals. In 1976, four nuclear engineers —three from GE and one from the Nuclear Regulatory Commission— resigned, stating that nuclear power was not as safe as their superiors were claiming. They testified to
Organic nuclear reactor of process heat instead of electrical power. It ran in this form until 1988. Indian officials have periodically expressed interest in reviving the concept. They initially received CANDU design materials during the period of the WR-1 experiment. To further lower operational costs, there have been several revivals of the WR-1-like concept. It is believed that an organic coolant purification system can be developed to handle the decomposition of the organic coolant, and research has begun to this effect. However, , no experimental system has been constructed. Organic nuclear reactor An organic nuclear reactor, or organic cooled reactor (OCR), is a
