| | As shown in the above table, the result with all interlock doors closed was 0.273 inches of water negative pressure in secondary containment with respect to atmosphere, which satisfied the Technical Specification 4.7.C.l.a. requirement. This SCLRT also demonstrated that the Unit 2 Reactor Building trackway interlock outer door has adequate sealing to maintain secondary containment integrity. Additionally, this test demonstrated that the Unit 3 material interlock outer door does not have adequate sealing to maintain secondary containment integrity. Dresden Administrative Procedure (DAP) 13-14, Unit 3 Reactor Building Material Interlock Access Control, is a posted procedure and provides adequate control of this interlock. |

Secondary Containment Leak Rate Testing Dresden Nuclear Power Station Commonwealth Edison Company Docket Nos. 50-237 and 50-249 Dear Mr. Davis As part of the Dresden Unit 3 pre-outage work a Secondary Containment Leak Rate Test (SCLRT) was performed on the Unit 2/3 Reactor Building.
The SCLRT was performed in accordance with Dresden Unit 3 Technical Specification 4.7.C.l.a., which requires that prior to refueling, Secondary Containment integrity must be demonstrated by maintaining )/=
0.25 inches of water vacuum in the Reactor Building with one train of the Standby Gas Treatment system operating at a flow of </= 4000 cubic feet per minute (CFM) under calm wind conditions (</= 5 miles per hour). On September 07, 1991, the SCLRT was performed in accordance with Dresden Technical Staff Surveillance (DTS) Procedure 1600-22. The results of the test are listed below.'2 U3 RX BLDG U3 RX BLDG SCLRT RX BLDG U2 RX BLDG MAT'L INTER- MAT'L INTER- RESULT, TRACKWAY INNER TRACKWAY OUTER LOCK INNER LOCK OUTER INCHES OF QQQKLQMXXQH MhXEMK .

/For
As shown in the above table, the result with all interlock doors closed was 0.273 inches of water negative pressure in secondary containment with respect to atmosphere, which satisfied the Technical Specification 4.7.C.l.a. requirement. This SCLRT also demonstrated that the Unit 2 Reactor Building trackway interlock outer door has adequate sealing to maintain secondary containment integrity. Additionally, this test demonstrated that the Unit 3 material interlock outer door does not have adequate sealing to maintain secondary containment integrity. Dresden Administrative Procedure (DAP) 13-14, Unit 3 Reactor Building Material Interlock Access Control, is a posted procedure and provides adequate control of this interlock.
This report is being submitted in accordance with Section 6.6.C.3.h. of the Unit 2 and Unit 3 Technical Specifications. Please direct any requests for further information regarding this topic to M. Blakemore, Technical Staff Systems Engineer, at extension 2421.
