A New Tool to Address Single Point Vulnerabilities

Jun 19, 2021In a nuclear power plant, a single point vulnerability (SPV) is a component or subcomponent that, if failure occurs, can cause a reactor or turbine to trip and the plant to go offline. Among plants built in the 20th century, about 1% of components are SPVs, with most in the turbine-generator side (not the reactor side) of the plant.

List of nuclear power accidents by country

Because nuclear power plants are large and complex, accidents on site tend to be relatively expensive. [7] The 1979 Three Mile Island accident in Pennsylvania was caused by a series of failures in secondary systems at the reactor, which allowed radioactive steam to escape and resulted in the partial core meltdown of one of two reactors at the

The environmental impact of nuclear power generation

Jun 15, 2021Nuclear impacts on the environment. True, nuclear power may not be as obviously pollutive as coal, but the chemicals it releases can contaminate groundwater, air and plants – and this pollution lingers for decades.. While nuclear energy does not produce carbon emissions directly, the construction of plants, uranium mining and manufacturing operations all produce C02 commissions
