7 (2) Training The inspector reviewed the plant training records and noted that the training coordinator's training data sheet indicated that the brigade training was up-to-date. The training records for three brigade leaders and seven brigade members were reviewed. The records indicated that each member had attended the Mississippi State Fire Academy and received site specific training within the past 12 months, received a physical examination within the past 12 months, and participated in the required quarterly drills and classroom training for CY1983.
The drill records were reviewed and it was verified that for the fourth quarter of 1982, and the first and second quarter of 1983, each operational shift had participated in at least one drill per quarter, except the drills for Shifts B and D had not yet been conducted for the second quarter of 1983. These drills were scheduled to be conducted before the end of the quarter.
The annual drill with the local county public fire department was conducted on September 23, 1982. The licensee's evaluation report indicated that this drill was satisfactory.
(3) Fire Brigade Equipment A sufficient quantity of turnout gear (coats, boots, helmets, gloves, etc.) was provided to equip 16 fire brigade members. This equipment was stored in four lockers on three elevation of the turbine building and on the 139' elevation of the auxiliary building and appeared to be adequately maintained.
A total of 18 self contained breathing apparatus was assigned to the fire brigade. Additional units were available from the health physics group. The licensee estimated that the total quantity of self contained air breathing equipment exceeded the minimum 6-hour supply required by the NRC. The maintenance of this equipment
,

.
appeared to be satisfactory. However, the licensee had not pr"ided the portable skid-mounted air compressors approved for breathing air application as committed by response to NRC/FSAR Question 013.17. This is identified as Deviation Item (416/83-26-01), Failure to Provide Skid-Mounted Air Compressor for Breathing Air Application.
c.
Plant Tour A tour was made of the plant to review general housekeeping, control of flammable and combustible materials and general fire protection and prevention features. The general housekeeping was considered satis-factory for a plant undergoing the transition from the construction to the operational phase. Most of the temporary construction materials had been removed; however, several temporary structures remained in place. These are scheduled to be removed or provided with appropriate fire protection features prior to the plant entering the criticality mode. Refer to above paragraph 3.d.
Six welding permits and four temporary combustible storage permits issued on June 28, 1983, were reviewed. These permits adhered to the requirements of Procedures 10-S-03-3, Control of Ignition Sources, and 10-S-03-4, Control of Combustible Materials.
The following fire protection systems were inspected and found to be in service: automatic sprinkler systems for diesel generator building, upper and lower cable spreading rooms, and auxiliary building elevations 93'-103', 119', and 139'; "Halon" system for computer room; carbon dioxide systems for penetration and switchgear rooms (System Nos. NIP 64D 200A-D, 201A-D, and 217A-B); and, six interior fire protection control valves (Valve Nos. F134, F194, F195, F200, F206 and F291).
Five fire hydrant equipment houses (Nos. 08, 09, 10, 23, and 25) were inspected and found to contain the required quantity of equipment. The equipment was satisfactorily maintained.
d.
Surveillance Inspection and Tests of Fire Protection Systems The inspector reviewed the following inspection and test documents for dates indicated to verify that the inspections and tests were accomplished within the time specified by the Technical Specifications (TS). Surveillance was considered satisfactory except as noted.

(13) 06-ME-SP64-SA-0002, PGCC Halon System Bottle Weight and Pressure
' Check: Weight and pressure inspection of the 21 PGCC Halon System cylinders were satisfactorily conducted on various dates during May and June 1983. Test records were not available to indicate if any previous inspections had been conducted. TS Section 4.7.6.4.b requires the weight and pressure of each Halon cylinder to be verified at least once per 6 months. The failure to verify the pressure and weight of these cylinders prior to licensing and 6 months prior to the most recent inspections is identified as Violation (416/83-26-02), Failure to Conduct Semi-annual Weight and Pressure Verification of the PGCC Halon Systems. The licensee in February 1983, issued Procedure 06-ME-SP64-SA-0002 for the inspection of the PGCC Halon systems. Current inspection and test scheduling procedures should assure that future inspections will be accomplished within the required time.
