APPENDIX R FIRE SCENARIO INVOLVING MULTIPLE HIGH IMPEDANCE FAULTS

"TMI Issue Report # 329440 identifies an issue associated with a previously unidentified/unanalyzed Appendix R fire scenario involving multiple high impedance faults. An engineering evaluation has determined that certain safety related power circuits are not protected against multiple high impedance faults, which in combination with a fire in the 305' elevation of the Control Building, could cause a loss of safe shutdown functions from the control room and the remote shutdown panel. An hourly fire-watch has been established in the affected fire zone in the 305' elevation of the Control Building as an interim compensatory measure."


The NRC Resident Inspector will be notified.

23 TRITIUM EXIT SIGNS UNACCOUNTED FOR AFTER REMODELING OF BUILDING

In December, 2003, the County College of Morris started remodeling several campus buildings. In the pre-planning stages of the construction effort, the electrical contractor accepted responsibility to properly dispose of hazardous materials recovered or during the remodeling effort which included the 23 tritium exit signs. On May 3, 2005, the college requested proof of disposal from the contractor. The contractor was not able to produce the required documents. Upon further investigation, the contractor is currently unaware of the location or disposition of the missing signs.

The exit signs were Everglo model 700C/10 with average manufacturing date of June, 2002. Maximum tritium content of each sign was 25 Curies.

The college has notified New Jersey Department of Environmental Protection of the missing signs.
