SUBJECT:

CLOSE0VT OF TAC NOS. M71758 AND M71759, " POINT BEACH 1 AND 2 -

REACTOR VESSEL UPPER SHELF ENERGY" Generic Letter (GL} 88-11 (MPA A-023), "HRC Position on Radiation Embrittlement of Reactor Vessel Materials and its Impact on Plant Operations,"

dated July 12, 1988, required licensees to submit the results of their technical analysis of Revision 2 to Regulatory Guide 1.99, " Radiation of Reactor Vessel Materials." A measure of radiation embrittlement discussed in RG 1.99 is the Charpy upper-shelf energy of the reactor vessel materials. The Point Beach units were included in a list of reactor vessels most susceptible to having a low upper-shelf energy. Consequently, TAC numbers 71758 and-71759 were opened' at the request of EMCB to perform a review of w sconsin Electric Power Company's response to GL 88-11 related to the upp"anelf energy of the Point Beach reactor vessels. However, based on a B&W owners group determination that Point Beach is bounded by analyses conducted for Turkey Point Units 3 and 4 and Zion Units I and 2, EMCB does not intend to do a detailed review of the upper Shelf issue for Point Beach. Accordingly, the TACs for these reviews are no longer necessary.

This memorandum closes out all activities associated with TAC Nos. M71758 and M71759.
