Dear Sir:

Florida Power Corporation (FPC) hereby submits the information requested in NRC Bul 6etin th. 92-01, " Failure of Thermo-lag 330 Fire Bt.rrier System to Maintain Cabling in Wide Cable Trays and Small Conduits Free from Fire Damage." The information provided includes identification of the areas of tne plant which contain Thermo-lag 330 (TSI) fire barrier material protecting equi) ment providing safe shutdown capability, identification of the areas whic1 use TSI material for protecting small diameter conduit and wide trays, the compensatory measures implemented in accordance with Crystal River Unit 3's (CR-3) Technical Specifications for an inoperable fire barrier, and the measurcs being taken to ensure or restore fire barrier integrity. A general floor plan including the location of fire detection devices, fire suppression coverage, and the route of the hourly roving fire watch is provided to aid in understanding the information contained in this submittal (Attachment 3). Identification of TSI Haterial Protecting Safe Shutdown Capability A review of the fire protection design information for Crystal River Unit 3 has confirmed that 1-hour and 3-hour pre-formed TSI material was installed at this f cility. The areas nr the plant which contain TSI fire barrier material that provide safe snutdown capability are listed in Attachment 1. The use and location of the TSI material was determined using drawings, circuit layouts, modification documentation, and plant walkdowns. h' .,. 3 e e t a f,) ) 9200030283 920729 PDR' ADOCK 05000302 jl O FDR A Florkta Progress Company i :

1 'o 9 lJ.' S. Nuclear Regulatory Commission 3F0792-12 Page 2 i TSI Haterial Protecting Small Conduit and Wide Trays The areas of the plant containing TS1 fire barrier material protecting small diameter conduit and wide trays that provide safe shutdown capability are identified in Attachment 2. The conduit identified represent small diameter conduit of less than four (4) inches, and the wide cable trays are those with a uidth of greater than fourteen (14) inches. Compensatory Measures The compensatory measures which have been established at CR-3 include the following. The hourly roving fire watch which was in-place at CR-3 to cover degraded fire barriers was expanded to cover those areas of the plant that rely on TSI material for protection of safe Sutdown capability and which are equipped with fire detection equipment. A continuous fire watch was initially estsblished in three areas, AB-95-3K, AB-95-3W and AB-95-3Y, that rely on TSI material for protection of safe shutdown capability and that were not equipped with fire detection devices. The continuous fire watch was replaced with the hourly roving watch once new, portable fire detectors were installed and operable. The new portable fire detection system consists of ionization and photoelectric smoke detectors which are linked to a central alarm panel. The system is a class 'B' supervised system which provides either fire or trouble alarms at the central panel and to the main Control Room and to the Nuclear Security Central Alarm Station. The alarm capability to the Control Room and the Nuclear Security Central Alarm Station is accomplished via the use of an automatic dialer and a dedicated telephone circuit. The remote central panel is monitored on an hourly basis by the roving fire watch. These compensatory actions are in accordance with the requirements of CR-3's Technical Specification Section 3.7.12. " Fire Barriers." The houriy roving fire watch presently covers all areas in the plant that contain TSI material used to meet the fire barrier criteria. The areas covered by the hourly roving fire watch, and the designated route are provided in Attachments 2 and 3, respectively. J florida Power Corporation's determination o the type of fire watch coverage was made based on the following. All of tb areas containing TSI-protected safe shutdown equipment were first identified followed by a determination of the size of the conduit and cable trays routed through each area. For the purposes of establishing the fire watches, areas containing small conduit, less than four (4) inches, and/or wide cable trays, greater than fourteen (14) inches, were identified as requiring compensatory measures. The determination of which type of fire watch, hourly roving or continuous, was made based on the availability of detectors in the area. If detectors were present and operable in the area contain E.g the TSI protected conduits or trays, an hourly roving fire watch was estabiished. if no detectors were present and operable in the room, a continuous f' e watch was posted. Conduitsoffour(4) inches and greater and cable trays less than or equal to fourteen (14) inches in size were not considered necessary for inclusion in the compensatory measures.

0.' S. Nuclear Regulatory Commission 3f0792-12 4 Page 3 Nwever, ace the required arms were identified, it was decided that the roving watch would cover all areas containing TSI material used for safe shutdown capability since it-did not adversely affect the ability of the watch to perform the hourly functions. Heasures Taken to Ensure or Restore Fire Barrier Integrity Florida Power Corporation is continuing to review the information provided concerning the test failures of TSI material and its application at CR-3. A review of the installation information at CR-3 has shown the installation was accomplished in accordance with the manufacturer's reconunendations as outlined in TSI Technical Note 20684, Rev. V. November 1985, and that additional actions were taken to ensure the integrity of the TSI material used in the

plant, for example, the TSI material joints were buttered with trowel grade TSI material (both inside and outside), supports consisting of stainless steel tie wiras and banding materials were installed, in many cases, every six (6) inches as opposed to the reconunended twelve (12) inches, and trowel grade TSI material was installed on the outside of supports, conduits, and cable trays to encapsulate the items being protected.

A typical installation included supports on one (1) inch centers around bends and additional banding on the averaga of every four (4) to six (6) inchas for straight sections. The combustible loading for each fire area was reviewed along with the calculated fire durations. Actions have been initiated to remove or relocate combustible material from areas where TSI is present to reduce the potential for fire initiation-and to minimize fire severity and duration. In many cases, the calculated fire duration is less than the reported " failure" time for the TSI material under the tested configurations. Restoration of the TSI fire barrier material is presently being evaluated. Appropriate actions to restore fire barrier operability are being coordinated by NUMARC. We understand this program will include establishment of a test database, development of guidance for applicability of tests,' development of generic installation guidance, and consideration and coordination of additional testing as appropriate. We will support efforts to resolve the TSI fire barrier material in a timely manner, and will apply the results of these L efforts, when completed, to the TSI installations within the scope of Bulletin 92-01. Summary Crystal River Unit 3 has TSI fire barrier material installed and relies on the .naterial for one and three hour prctection for safe shutdown capability. Compensatory measures are in place in accordance with the facility Technical Specifications, and activities are in process to restore the fire barrier i-operability for safe shutdown capability. The ' appropriate compensatory l measures will remain in effect until the TRI fire barrier operability issues l. are resolved. We are coordinating with NUMARC to assure the industry perspective is evaluated and to maintain consistency in our actions. Florida y y .e-. ~-

p d.5.NuclearRegulatoryCommission 3F0792 12 Page 4 Power Corporation is in agreement with the NRC that the TSI testing failures are important issues that require immediate attention. We also agree with the staff's assessment that the relative safety significance of the fire barrier concern is low, since the TSI material still provides a measure of protection and, as stated above, the fire areas have lo. ruel loads, controlled ignition sources, fire detection and suppression equipment, and the facility has a trained fire brigade capable of responding quickly and efficiently to any fire emergency. We will continue to evaluate the long term actions necessary to fully restore the operability of the fire barriers in q::estion, and will provide additional information in support of these actions in a timely manner. Sincerely. 0
