This item remains ope (Open) Inspector Followup Item (261/79-29-06), Actuation devices for preaction sprinkler system in solid waste handling roo CP&L's letter of January 28, 1980 to NRR (Serial N NO-80-132) requested a supplement to the Fire Protection Safety Evaluation Report (FPSER) to change the method of actuation for this system from smoke detectors to heat detectors. This item will remain open pending the change to the FPSE.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve noncompliance or deviation New unresolved items identified during this inspection are discussed in Paragraphs 5. a. (2) and 5..
Fire Protection Program Fire Protection Modifications The inspector evaluated the licensee's corrective action on the following fire protection modifications as described in CP&L's letters of March 18, 1980 (Serial N NO-80-430)
and June 12, 1980 (Serial No. NO-80-896)
to NR (1) Fire Pump The drive for the unit n propane engine-driven fire pump is to be replaced with a diesel engin This installation had not been accomplished prior to this inspectio Therefore, the storage arrangements for the diesel engine, batteries and engine controller were reviewe The engine and batteries were found stored outside and the engine controller in a temporary wood frame, metal clad shed with earth floo This shed was also occupied as a welding sho None of the items were tagged for identification, traceability and statu Technical Specifications Section 6.8 requires establishment of Fire Protection Program implementation procedure Construction Procedure AP-IX-04, Material Storage, establishes the requirements to assure that safety related components and fire protection items, are stored to minimize the possibility of damage or degrada tion due to corrosion, contamination, deterioration or physical damage. Section 4.2 of Procedure AP-IX-04 requires items such as engine controllers and batteries to be stored in a (Class 1) fire resistant, tear-resistant, weathertight, ventilated, temperature controlled building or equivalent enclosur Items such as diesel engines are required by Section 4.3 of Procedure AP-IX-04 to be stored in a Class 2 standard storage building which meets the requirements of a Class 1 building except temperature control is not require All fire protection materials are required by Section 4.6 of Procedure AP-IX-04 to be tagged for identificaton, traceability and statu The failure to properly store and identify the above fire protection equipment is identified as Noncompliance (Infraction) Item (261/80-26-01),
inadequate storage of fire protection equipment and component (2) Containment Fire Protection System A standpipe system is being installed for the containment areas and water spray sprinkler systems are being provided for each reactor coolant pump and the electrical penetration are These systems were approximately 90% complete during this inspection The inspector noted that the design and installation appeared to conform to the commitment in CP&L's letter (Serial No. NO-80-896)
of June 12, 198 However, the standpipe system and reactor coolant pump water spray systems are both supplied by the same piping main which does not conform to the single failure criteria as stated in FPPR Section 4.4.5.3.a. The adequacy of this system is currently being evaluated by NRR; therefore, this item is identified as Unresolved Item (261/80-26-04),
containment fire suppression systems does not meet the NRC single failure criteria, and will be reviewed upon completion of NRR's evaluatio The containment fire protection piping systems are being inspected and system tests witnessed by the licensee's QA/QC grou Each weld is visually inspected in accordance with procedures (NDEP 601-RD, CQC-19-1 and WP-500-RI)
by qualified inspector The systems are also being inspected by QA/QC mechanical inspectors using construction inspection procedures (CQC-12 and CQC-23)
to assure systems will meet the design requirement The water spray system for each reactor coolant pump is to be automatically activated by an existing fire detection system installed in each pump ba The existing system utilizes a heat detector and a flame detecto It appears that the flame detectors may not be suitable for use in the installed location due to high temperature and radiation in the are The location and spacing
-4 of the single heat detector in each pump bay appears inadequat The licensee has identified these problems and iscurrently reeval uating this fire detector installatio Therefore, this item is identified as Unresolved Item (261/80-26-03), adequacy of fire detection system for reactor coolant pumps, and will be reviewed during a subsequent NRC inspection. Also, the actuation circuit from the alarm panel to the deluge trip panel is not supervise This item is identified in above paragraph 3.e. as an Inspector Followup Ite Plant Tour A tour was made of the plant areas to inspect the fire protection modification in the containment area and to assure that the fire sup pression and detection systems were in servic All fire protection systems were found to be in service, except the gas suppression systems for the diesel generators, cable vaults, cable spreading room and switchgear rooms. These systems are not required to be in service by the Technical Specifications when the plant is shut down. Therefore, this is not a discrepanc In the containment area several welding and cutting operations were observed in which the personnel were not following the fire prevention safety requirements of the licensee's procedures contained in Plant Operating Manual -
Volume 19, Hotwork Procedure FP-1. Procedure FP-1 requires the following:
a permit for all welding and cutting operations; floors beneath welding and cutting operations to be cleaned of combust ibles; a fire watch to be provided adjacent to the operations; and, a fire extinguisher to be provided in the vicinity of the hotwork operation Of the welding and cutting operations being conducted in the containment practically all were violating at least one of these requirements and several were violating all of these requirement This is a failure to follow the fire protection program implementation procedures required by Technical Specifications Section 6.8 and is identified as Noncompliance (Infraction)
Item (261/80-26-02),
failure to follow requirements of fire prevention welding procedur Also, while touring the containment area several sections of open piping were noted in the fire protection piping system in which no work was being conducted. The open ends of the piping system were not sealed to prevent the entry of contaminants as required by CP&L Con struction Procedure WP-107, Cleaning and Cleanliness Maintenance of Piping System This is identified as another example of Noncompliance (Infraction) Item (261/80-26-01),
inadequate storage of fire protection equipment and component Throughout the plant site compressed gas cylinders were improperly stored. Cylinders were not protected against mechanical damage, valve covers were not in place, fuel and oxygen cylinders were not separated and cylinders were stored adjacent to combustible material The licensee agreed to consider the preparation of a new procedure for the
-5 storage and handling of compressed gas cylinder This item is identi fied as Unresolved Item (261/80-26-05), preparation of procedure for handling and storage of compressed gas cylinders, and will be reviewed during a subsequent NRC inspectio Fire Protection Audits The most recent audit of the fire protection program, required by Technical Specifications Section 6.5.4.1.g.,
to be conducted by the CP&L Corporate Nuclear Safety QA Audit Section, Audit QAA/20-18 of June 18-22, 1979, was reviewe This report identified one discrep ancy, documentation not available for test on one fire protection system. This item had received appropriate corrective action. The licensee advised that the annual fire protection audit required by Technical Specification Section 6.5.5.1 is conducted by the fire insurance carrie The adequacy of this audit is currently under evaluation by NRR and this item will be reviewed upon completion of NRR's evaluatio Surveillance of Fire Protection Systems The following fire protection system surveillance inspection and test procedures and recorded test data from January 1980 through August 1980
were reviewed and discrepancies noted:
(1) PT-9.OA, Unit 2 Motor Driven Fire Pump and Fire Detection System (Monthly)
No discrepancies note (2) PT-9.OB, Unit 2 Engine Driven Fire Pump and Water System Valves (Monthly)
Inspection frequency was satisfactory. However, refer to paragraph (3) PT-9.3, Inspection of Fire Protection Systems (Annual)
No discrepancies note (4) PT-9.4, Portable Fire Extinguishers, Fire Hose Stations and Houses (Monthly)
No discrepancies note (5) PT-9.5A thru 9.5G, Low Voltage Fire Detection System (Semi-Annual)
No discrepancies noted, except test has not been conducted on systems covered by PT-9.5G. These systems are in the containment and are to be tested prior to plant returning to full power. The systems covered by PT-9.5A through 9.5F were tested during June
-6 1980. None of these systems are included in the existing Technical Specifications but are included in the proposed revised Technical Specification The licensee is to conduct future semi-annual inspection and tests of these system (6) PT-9.7, Inspection of Engine Driven Fire Pump Engine (Refueling)
This inspection is not to be accomplished during this Refueling outage since the LP gas engine is to be replaced with a new diesel engin (7) PT-9.9, Emergency Diesel Generator "Cardox" System No discrepancies note (8) Fire Barrier Penetrations Currently there is not a procedure for an inspection of all fire barrier penetrations (cable, doors,, dampers and mechanical pene trations) as required by Technical Specification Section 4.14. However, the licensee advised that a procedure is being prepared to be used for the next scheduled inspection due in mid 198 The previous inspections were conducted in late 1979 when the new fire doors, dampers and penetrations were provided during this extensive fire protection modification progra Except as noted above, within the areas examined, no additional items of noncompliance or deviations were identified.
