E1.7 Inadeouate 50.59 Review identified For Safety Review item 96-016
a.
Insoection Scooe
The inspectors reviewed SRI 96-016, "1996 FOI identified USAR Changes,"
Revision 0, Addendum 4, dated October 23,1996. The SRI provided a description
and evaluation of an USAR change that was identified from the HELB design basis
document Follow-On item (FOl) 94-0012, " Pipe Breaks at RHR, CS and SBLC
Containment Penetrations," dated February 15,1994.
b.
Observations and F,iMne:
The SRI proposed 16 changes to the USAR concerning pipe breaks at containment
penetrations, which, on the surface, appeared to be mostly editorial in substance
(e.g., the changes provided additional information and references for clarification,
minor wording changes which supposedly did not affect the licensing- or
design bases of the plant. However, upon further review, the inspectors noted that
the SRI revision was much more complicated; the licensee was actually redefining
l
high energy line break locations.

The inspectors noted that, although the SRI provided a " Reason" section for each
identified change, not all reason sections adequately explained the basis or provided
justification for the change. For example, on page 6, the reason for changing
20 gallons to 2 gallons was not adequately justified (i.e., What calculation, if any,
was used to confirm this volume? What isometric drawing (s) showed the pipe
l
location? What was the siaeed length of the pipe?). The licensee was able to
i
answer each of these questions satisfactorily for this case: however no written
i
justification was provided. The failure to provide a bases for determining that these
changes did not involve a USQ is considered an example of a violation of 10 CFR 50.59(b)(1) (50-263/96009-10(DRS)).

licensee committed to revising the administrative procedure for special tests to
i
address offsite testing being performed to address onsite issues. The licensee also
committed to provide training to the engineering staff regarding the requirements
for written procedures and acceptance criteria. The inspectors observed that the
actions taken would ensure that the particular violation of test controls would not
recur. This item is closed.
E8.2 (Ooen) Unresolved item 50-263/96005-03: Justification for use of SRI 95-002 to
isolate cooling water to the core spray motors. As discussed in Section 04.1, the
licensee had committed to reevaluating the test results prior to isolating cooling
water to the core spray pump motors. As of the inspection, no official evaluation
i
had been performed and SRI 95-002 had not been revised. This item remains open.
'
E8.3 (Closed) Unresolved item 50 263/96005-04: The licensee reperformed the RHR
room heatup calculation. The new calculation, CA 96-113, " Temperature of RHR
Rooms During DBA LOCA," revised the input assumptions discussed in the
unresolved items and determined that the maximum room temperature would be
j
approximately 141 F. The inspectors only reviewed the input parameters, such as
river temperature, service water flow to the coolers, and motor heat input, The
inspectors concluded that the concems raised in Inspection Report 96005 were
resolved. This item is closed.

Exit Meeting Summary
On January 8,1997, the inspectors presented the inspection rest!!!e to the Plant Manager.
The licensee acknowledged the findings presented.
The inspectors asked the licensee whether any materials examined during the inspection
l should be considered proprietary. The licensee identified some of the documents used in
l this inspection as company proprietary; these are so noted in the list of documents
l reviewed at the end of this report. The proprietary information was either destroyed or
l returned to the licensee following issuance of the inspection report.
