Dependency of first peak power on reciprocal period in zero reactivity temperature coefficient system

Yamane, Yuichi  

In the criticality accident of nuclear solution fuel for which reactivity temperature coefficient was zero, the dependency of the first peak power on its reciprocal period was investigated and it was found that the first peak power was proportional to the reciprocal period and showed large value depending on the difference between the initial and boiling temperature under the condition in which radiolytic dissolution gas and boiling gas void be effective right after the beginning of boiling of the solution.
