documents changes made to the Individual Plant Examination (IPE) Report which involved the corTection of a valve tag number discrepancy. This discrepancy did not affect any conclusions drawn in the report.
'F It was identified that IPE Report EA-RA-93-001-M, dated January 15,1993, (TAC M74459) contained 'a discrepancy associated with the Reactor Core Isolation Cooling (RCIC) System test return isolation valves. The applicable paragraph contained on Page 229 of the report was as follows.
i The RCIC test return lines wem not considered as potential diversion paths because the 1
-isolation valve'(IE51*MOV019) in this line is normally closed and is signaled to close on a RCIC actuation signal. Themfom, the probability that this line could divert flow Jaway from 'the reactor is considend very low.

. Page 2 of 2 The underlined portions below indicate the changes implemented in the revised paragraph:
- The RCIC test return line to the CST is not considered as potential diversion path -
. because the isolation valves (IE51 *MOV022 and 1E51 *JMOVF059) in this line are i
. normally closed and are signaled to close on a RCIC actuation signal. Therefore, the probability that this line could divert flow away from the reactor is considered very low.
