ATTACHMENT Rev. 1 On May 24, 1990 the NRC requested additional information on the Emergency Power System Enhancement Project with respect to code issues. The following provides responses to the questions posed by the NRC.

(1) What piping codes are used for system and components associated with the emergency diesel engine?

(2) What allowables are used for the safe shutdown earthquake loads associated with safety related piping and components supplied under ANSI B31.1 (1986) ?

Per ANSI B31.1 (1986) paragraphs 102.2.4, 102.3.3 and 104.8.2, a stress allowable of 1.2 S" has been used.
