Subject:
LaSalle County Station Units 1 and 2 Proposed Technical Specification Special Test Exception for S/RV Testing NRC Docket Nos. 50-373/374 The purpose of this letter is to transmit a proposed Technical Specification to allow Safety / Relief Valve Testic.g as required by Technical Specification 3/4.6.2; Containment Systems.
The proposed Technical Specification allows elevated Suppression Chamber Water Temperature to facilitate data collection in the regions of interest.
The proposal is enclosed for inclusion in the LaSalle County Technical Specification.
If there are any questions in this regard, please contact this office.
Very truly yours, bb Sar % M C. E.

v ATTACHMENT SPECIAL TEST EXCEPTION 3/4.10.7 SUPPRESSION CHAMdER WATER TEMPERATURE LIMITING CONDITION FOR OPERATIC 3.10.7 Ine requirements of " specification 3.6.2.1 that pool water 0
maximum average temperature be limited to 100 F during Opera-tional Conditions 1 and 2 may be revised during S/RV Test performance to limit the maximum average temperature to 1100F during Operational Conditions 1 and 2.
APPLICABILITY:
Operational Conditions 1 and 2 Action:
Stop all testing which adds heat to the suppressicn chancer and restore the average temperature to less than or 0
equal to 110 F within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or be at least hot shutdown within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
SURVEILLANCE REQUIREMENTS 4.10./ At least once every 5 minutes during testing, suppression chamber average temperature will be verified to be less than or 0
equal to 110 F.
BASES 3/4.10.7 Suppression Chamber Water Temperature - In order to obtain information on thermal mixing of the suppression chamber water during S/RV discharge, extended blowdowns are performed as part o f the In-Plant SRV test.
To best understand the effects of these blowdowns, they must be performed over a maximum temperature range.
In order to collect data in the region of interest, the suppression chamber shall remain operable with the 0
pool water maximum average temperature of 120 F.
Conservative calculations show that with restricted reactor power history and operation at less than 60% as will be the case during the test, the above temperature limit does not enable the suppression chamber water temperature to exceed acceptable limits.
