Chernobyl - Causes - Operating Instructions and Design Deficiencies Found
... These included operating the reactor at a low power level – less than 700 MW – a level documented in the run-down test program, and operating with a ... experts notwithstanding, regulations did not prohibit operating the reactor at this low power level ... However, regulations did forbid operating the reactor with a small margin of reactivity ...
Pressurized Water Reactors - PWR Reactor Design - Moderator
... Pressurized water reactors, like all thermal reactor designs, require the fast fission neutrons to be slowed down (a process called moderation or thermalization) in order to interact with the nuclear fuel and ... are slowed down and hence reducing the reactivity in the reactor ... This property, known as the negative temperature coefficient of reactivity, makes PWR reactors very stable ...
