The inspectors identified a non-cited violation of
10 CFR 50.71(e) for the failure to update the
Updated Final Safety Analysis Report (
UFSAR) to include information related to those portions of the nuclear
service water (RN) system that are shared between Units, as reflected in License Amendments issued for both Units on January 4, 1988. This issue was greater than minor because the failure to include in the
UFSAR the designation of which portions of the RN system were shared between units, as described in the License Amendments, was material to the NRCs review of the licensees response to
Generic Letter 91-13, Request for Information related to the Resolution of Generic Issue 130, Essential
Service Water System Failures at Multi- Unit Sites. The licensees response revealed that they had procedures that allowed sharing of the RN discharge, which was specifically designated as not shared in Figure 7-1 of the Technical Specifications. As such, the
UFSAR could not be relied upon to determine the shared portions and their safety implications. However, the inspectors found no subsequent changes made to the facility that were based on the erroneous information in the
UFSAR section. Consequently, this issue was considered to meet the criteria of a
severity level IV violation. This finding has a cross-cutting aspect of thorough evaluation in the area of problem identification and resolution [P.1.(c)]. (Section 1R11.1
