b.
Fire Brigade Organization and Training (1) Organization The licensee stated that the plant fire brigade is composed of various plant employees with a minimum of five members maintained onsite at all times. Normally, the fire brigade leader and one member comes from the operations group and three members are from security.
(2) Training and Drills The inspector reviewed the recent plant training records and noted that routine brigade training was conducted for the first quarter of 1981, but training had not been conducted for the second
,
quarter.
However, the licensee had scheduled training for all fire brigade members for July and stated that this training would be compelted prior 'to July 21, 1981, which would meet the 21 day grace period permitted by the licensee's Fire Protection Plan.
The licensee stated that future training would be scheduled to meet the quarterly requirement.
Records of fire brigade drills conducted for 1980 and 1981 were not all stored with the training records. The licensee was able to locate a number of drill data sheets but drills were not conducted every 92 days for each brigade as required by Section 7.2.3 of the licensee's Fire Protection Plan.
For 1980, three (shifts A, B, and D) of the four cecurity shifts did not parti-cipate in two quarterly drills and one (shift C) did not parti-cipate.in one quarterly drill.
For the first two quarters of 1981, one of the shifts (shift B) did not participate in a quarterly drill.
For 1980, two of the four operations shifts (shifts B and C) did not participate in two quarterly drills and two (shifts A and D) did not participate in one quarterly drill.
For 1981, one shift (shift D) did not participate in a quarterly drill. This data was obtained by the inspector from the licensee by phone on July 16, 1981. The failure to meet fire brigade drill training requirement is identified as a violation item in Report Nos. 338/81-19 and 33981-16. A similar violation was identified in Report 338/80-03.
(3) Equipment Most of the fire brigade members have been issued protective turnout gear (coat, pants, boots and helmet). Also, five addi-tional sets of turnout gear is available and stored adjacent to the control room.
.

.
.
.
.
The fire brigade has assigned 12 self contained breathing apparatus and 24 spare cylinders which are stored in the turbine building adjacent te the control room. Additional units are also available from the nealth physics group, if needed. The brigade cylinders are refilled by means of a cascade system.
This j
arrangement meets the commitments to the NRC.

c.
Facility Tour (1) A tour was made of the plant to verify that the fire protection
,
modifications made as a result of the Fire Protection Safety Evaluaticn Report were completed.
Refer to paragraph 7 for details on i 2ms inspected. During the tour, the following fire protection systems were also inspected and verified to be opera-tional:
(a) Fire Alarm System (b) Low pressure carbon dixoide system for cable tunnels and vaults, charcoal filters and diesel generators (c) High pressure carbon dioxide system for fuel oil pump rooms
(d) Halon system for control room
!
(e) Interior fire bose station for auxiliary building, fuel,
building and turbine building (f) Fire hydrant equipment houses A and C (2) The inspector found the fire doors between the turbine building ge' erator rooms 2J and 2H (Doors T-16 and T-18),
and diesel n
,
between turbine building and emergency switchgear room for Unit 2 5 9oor S-53-11) and the doors between emergency switchgear rooms v' stairway (doors S-54-6 and S-54-7) not latched due to dsfective hardware.
The licensees's procedure PT-105.1.1, Fire Door Inspection - Turbine Building, Control Room and Health Physics, states that for fire doors to be functional they must close and latch.
This item is identified as Violation Item (338/B1-18-01 and 339/81-15-01), Nonfunctional fire doors for
!
emergency switchgear and diesel generator rooms.

- This item was not inspected
- Refer to Paragraph 5.b for additional information
"Open" Item Contains Discrepancies.
Refer to Paragraph 5.b for Details
" Closed" Visual Inspection and Random Review of Documenta-l tion Records Indicates That This Item Appears Satis-f l
factorily Completed j
b.
Findings Additional information on the "Open" items and items marked "*" in Paragraph 5.a is listed below. The below listed numbers correspond to the numbered items in paragraph 5.a (2) Fire hose has not been provided at each standpipe hose outlet in the containments as stated in Table 1 of the FPSER.
The hose and equipment are located in cabinets adjacent to each personnel hatch.
The licensed advised that a ' commitment was not made to install fire hoses at each standpipe outlet but that hose was to be provided in cabinets adjacent to the personnel entrance outside each containment.
Enclosure 1 to VEPCO's letter Serial No. 4581080178 to NRR dated September 29, 1978, states that dry hose connection standpipes will be located within the reactor containment with " lengths of hose (to be located) immediately outside of personnel hatch in auxiliary building el 291 ft".
The licensee is to resolve this discrepancy with NRR.
This item was previously identified as an unresolved item in Report Nos. 338/80-42 and 339/80-39.
(7) VEPCO's letter Serial No. 148/0306679 to NRR dated June 11, 1979 stated that replacement of this damper was not necessa y since the ventiiation duct was schedule 40 pipe provided with two normally closed seismically qualified butterfly valves in series directly inside the control room wall which would provide the equivalent, or better than a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> damper. This evaluation was apparently acceptable to NP.R.

(16) In general, the installatian of the smoke detection systems do not -
fully meet the criterion of NFPA-72E, Automatic Fire Detectors, in many areas. The licensee stated that a commitment wat neve, made to the NRC for the installation of the detection systems to meet the provisions of NPFA-72E. However, the licensee has reviewed the existing design and installation and is to provide some additional detectors.
This is presently identified as an unresolved item. Refer to above paragraph 3.K.
(23) The fire dampers are not stt:ndard type dampers and documentation as to the fire resistant rating of these fire dampers is not available at the site. The license > is to provide NRC, Region II, documentation which will indicate the,1re resitant rating of these dampers. This item is presently -identified as an -unresolved item.
Refer to above pragraph 3.b.
(46) The fire detectors installed within the main steam valve houses are located approximately 10 feet beneath the ceiling which do not conform to the pn/isions of NFPA-72E.
The amount of combustibles within this area is exceptionally small; therefore, no additional changes to the detection system appears warranted.
Except as noted above, within the areas examined, no additional violations or deviations were identified.
