This Special Report is submitted in accordance with LaSalle Unit 1 and 2 Operating Licenses NPF-11 and NPF-18, Appendix A, and Technical Specifications 3.7.6 and 6.6.C.

Technical Specification 3.7.6 requires that all fire rated assemblies, including walls, floor / ceilings, cable tray enclosures and other fire barriers separating l safety-related fire areas or separating portions of redundant systems l important to safe shutdown v/ithin a fire area, and all sealing devices in fire rated assemby penetrations (fire doors, fire windows, fire dampers, cable and piping penetration seals and ventilation seals) shall be OPERABLE.

At 2230 hours0.0258 days <br />0.619 hours <br />0.00369 weeks <br />8.48515e-4 months <br />, on October 1,1996, roll-up Fire Door 615 was declared inoperable. The door was opened, for a period greater than seven days, to support activities performed during the Unit 2 Refueling Outage (L2R07). l Door 615 is located in Fire Zone 4E2 Unit 2 Auxiliary Electric Equipment  !

Room (elevation 731' of the Auxiliary Building). This door serves to divide this zone into two subzones (4E2-1 and 4E2-2). During the Refueling '

Outage, a temporary cable is being routed under Door 615 in support of LOP-MS-09 " Temporary Connection of Main Steam Line Plug Leakage Alarm." Although, a swinging type fire door is also available in the area, Door 615 was chosen because this door is not the main door used by employees and therefore the cable would be less likely to be damaged, i

o An Hourly Fire Watch had been established in accordance with the Action j Statement of Technical Specification 3.7.6 and this watch will remain in i effect until the door is closed. This compensatory measure along with the operable fire detection existing on both sides of the door and the oversight of the Fire Protection Administrative Program ensure the level of fire protection will not be reduced, if there are any questions or comments concerning this letter, please refer them to me at (815) 357-6761, extension 2212.
