SDG-1. RESPONSE T0 l.055 0F RCS INVENTORY DURING SHUTDOWN Rev. 4 (f 7/1/97 A. PURPOSE-The purpose of this guideline is to provide the actions necessary for maintaining core cooling and protecting the reactor core in the event that PRZR level is lost

'during shutdown operations when the RCS is intact or RCS level is'too' low to support operation of the RNS pumps during operation in.' reduced inventory conditions in the RCS.

CAUTION
  • Personnel working in containment should be warned before refilling the RCS to avoid inadvertent contamination of personnel working near RCS openings.
  • If RCS hot leg level remains less than (SLO 2) for greater than 30 minutes, automatic alignment for IRWST injection should be verified. l 5 Refill RCS

.v(~').

There is one key utility decision poin: in this guideline w hen the operator must initiate actions to protect personnel inside corr:ainment. In Steps 11 and 27, the operator is instructed to evacuate non-essential personnel inside containment. The ope *:ator will have to determine which personnel must be evacuated ,

I from containment at this time in the guideline.
