Shutdown initial meeting

Reserve Shutdown Requirements and Reactivity Worths The primary reactivity requirement for the reserve shutdown control (RSC) is to maintain shutdown (k < 0.99) indefinitely at or below the refueling temperature 192 C (377 F). Any partially inserted control rods or other fully withdrawn control rods are assumed not to be inserted in determining the RSC capability to meet this requirement, i.e., the maximum core operating excess reactivity is assumed to be held down by control rods and this excess reactivity is not a component of the requirement for the RSC. The reserve shutdown control equipment (RSCE) is also required to trip following the trip of the outer bank of control rods, and after some delay, for transients initiated by moisture ingress during power operation.
