Dear Mr. willne:
There are two core cooli=g =edes for S&7177 TA reactors at hish pressure.
i; These are CC50 coo 11=g and high pressure injection cooli=g. 0:5C cooling is lost Wes both - ais a:d ai-r*1 * = y feedwa:er are lost.
Therefore, 5&7 reccx= mends that operatics piants include instructions in their loss of Y.ais Teedwater c=arge::v procedure for the opera:or to zanually 3

The power operated relief valve (?017) on the pressurt.:er should be opened to allow
