Since the Renctor Ruilding may not be accessible at that time, the containment may not be able to be vented using this procedure.

The Operating Procedure did not properly address the ability of personnel in enter the Rescior Building during the time in which the procedure was to be used. The procedure was immediately revised to allow . containment venting to be accomplished from the main control room using existing espip-ment 1 Further evaluation : . unalerway in order to refine this procedure.

A modification to the systes is being stesigned in order to insure the ability to vent the Primary Containment following a IACA without requiring personnel to enter the Rear.tur Emilding. This modification will be installed during -
