(NOTARIAL SEAL)
TECHNICAL SPECIFICATION CHANGE REQUEST NO. 72 Replace pages 3/4 7-23, 3/4 7-24, B3/4 7-5, and B3/4 7-6 of Appendix A with Revised pages 3/4 7-23, 3/4 7-24, B3/4 7-5, and B3/4 7-6 of Appendix A.
Proposed Change Add the following sentence as a footnote for Specification 3.7.8.1:
"More than one filter system and more than one pair of exhaust fans may be inoperable for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing per Specification 4.7.8.1."
In addition, basis 4.7.8 was modified to encompass leakage from systems other than the ECCS.
Reason for Proposed Change in order to achieve proper air-aerosol uniformity mixing while performing in-place testing, the injection point for sample gas is made at a point before the duct divides into the individual filters. Likewise, the downstream sample point is on a common discharge duct into which all four filters exhaust. The only way to test leakage in a given filter, therefore, is to remove the other three filters from service. This change to Specification 3.7.8.1 allows the removal of the three filters from service for a period of twelve hours in order to test the given filter and not exceed the Action requirements.
Basis 3/4.7.8 was expanded to reflect actual exhaust system capabilities.
SAFETY EVALUATION The proposed change allows more than one filter system and more than one pair of exhaust fans to be inoperable for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for surveillance testing per Specification 4.7.8.1.b, e, or f.
This will have no adverse effect on plant safety cince the potential off-site dose due to a design basis accident is well within the guideline exposure indicated in 10CFR Part 100 regardless of whether credit is taken for operational filters.
