JUN 0 41965 MEMORANDUM FOR: Dennis M. Crutchfield, Assistant Director for Safety Assessment, DL FROM:

Daniel R. Muller, Assistant Director for Radiation Protection. DSI

SUBJECT:

FINAL DRAFT OF THE RIVER BEND UNIT 1 TECHNICAL SPECIFICATION - TABLE 3.3.2 OPEN ITEM (MEMO DATED 5/13/85, MULLER TO CRUTCHFIELD)

In the above memo, the Radiological Assessment Branch requested additional information in reference to Table 3.3.2-2, Ic, " Isolation Activation Instru-mentation Setpoints" indicating the setpoints for the containment purge isolation monitors were too high. GE responded on o/9/85 with a document addressing this open item.

Based on the above document the staff finds the setpoints acceptable.

In additicn, Mr. Dan Williams (River Bend Nuclear Engineer) informed us that the monitors in question are area monitors and not the High Range In-Containment Monitors, contrary to their apparent mischaracterization in the FSAR. He also indicated that the functional applicabilty and range of these monitors are consonant with the Reactor Building-containment purge isolstion detectors.

The staff suggested that Mr. Williams amend the originsi document so that it would conform with the FSAR, Table 13.3-8, "Onsite Assessment Equipment and Facilities,"

rather than NUREG-0737. Table II.F.1-3, " Containment High-Range Radiation Monitors". This open item in River Bend Tech Spec is closed pending the applicant's forthcoming" documentation.,

This review was performed by Sy Block, Frank Skopec, and John Minns/RAB.

Please contact J. Minns x27615 for any information pertaining to this review.
