Licensee Action on Previously Identified Inspection Items
!
(Closed) Open Item (50-305/81-19-01): Lack of specific Technical Specification surveillance requirement on RCS leakage. The inspector noted that on November 6, 1981 the licensee amended Table 4.1-3lof its Technical Specifications to require a weekly surveillance on RCS leakage.
No items of noncompliance or deviations were identified.
3.
RCS Leak Rate Determination Kewaunee Technical Specification 3.1.d limits Reactor Coolant System leakage to 1 gpm unidentified leakage and 25 gpm identified leakage.
-These LCOs specifically limit leakage from the primary coolant system and not leakage to the containment as inferred in the bases discussion.
Accordingly, leakage detection systems which determine leakage losses to containment from water and steam systems within containment cannot be used to meet the above Technical Specification limits. The inspector noted that the licensee had been monitoring containment sump levels and sump pump run times each shift to demonstrate compliance with T.S.3.1.d..The inspector concluded that this method was unacceptable.
The licensee stated that Surveillance Procedure No. SP 36-082 was being revised to address RCS leakage limits and would be finalized by June 1, 1982. The inspector noted that the procedure required a RCS water inventory balance be performed at least weekly whenever the' reactor was at power or in a hot shutdown condition. The inspector noted that this procedure had been conducted weekly for trending purposes, and upon review of test results,-noted that no Technical Specification limits had been violated.
.
The' inspector noted that the licensee had amended its Technical'
Specifications to require a weekly surveillance on RCS leakage, but recommended that it be done more frequently. The inspector also recommended that the 25 gpm limit on identified leakage be decreased to 10 gpm to be consistent with current industry practice and the

bases discussion, noting that a letter to this effect had been sent from the regional office to NRR.
No items of noncompliance or deviations were identified.
