ATTACHMENT A Item of Noncompliance As a result of the inspection conducted on November 2 through December 15, 1983, and in accordance with the NRC Enforcement Policy, 47 FR 9987 (March 9, 1982), the following violation was identified.

Technical Specification 6.2.A.7 requires that detailed written procedures for surveillance and testing requirements be adhered to.

LaSalle. surveillance procedure LTS 300-3, Step F.8, requires that the j

SBGT system be started up in accordance with station operating procedure i

LOP-VG-03.

Both Step F.8 of LTS 300-3 and Step F.1.g of LOP-VG-03 requires the secondary' Containment Integrity Test be performed with a system flow rate of 4000 CFM + 10%.

Contrary to the above, during the conduct of the secondary contain-ment integrity tr.st conducted on November 4, 1983, the inspectors noted that the system discharge flow rate as indicated in the control room, was in excess of 4500 CFM.

After the inspectors identified the problem, the licensee stopped the-test, adjusted the flow to approximately 4300 CFM,

-and restarted the test.

Corrective Action Taken and Results Achieved The corrective action taken, as noted in the "N0tice of Violation",

was to declare the tect invalid and restart the test using a more conservative flow rate of 4300 CFM.

The control room operator was given instructions to check the flow more frequently during the second test.

The flow recorder was also reviewed to assure that the 4000 CFM + 10% criteria was not exceeded.

The outcome of the test was not aTfected, since the results were well within the bounds of acceptance criteria.

Corrective Action Taken to Avoid Further Noncompliance b The test procedure (LTS 300-3) will be revised to require the test engineer to review the flow recording after the test for compliance with the 4000 CFM + 10%

Date of Full Compliance

[

Full compliance will be achieved by March 8, 1984 when the revision to the procedure LTS 300-3 is completed.

This item is tracked by AIR 01-83-35103.
