Fire Protection / Prevention Prooram (64704)

'

a.

Fire Protection Administrative Procedure Review

The inspector reviewed the licensee's fire protection program procedure for technical adequacy and for proper implementation of

the fire protection program. The procedure reviewed was.S0123-FP-1,

',

" Fire Protection Program," Revision 2, effective date February 9,

1993. The recent changes to this procedure were for fire protection j

responsibilitj realignment. The inspector found that the procedure changes wore technically adequate to properly implement the fire

protection program.

l b.

Fire Department Staff Medical Qualifications

!

,

The inspector randomly sampled medical records for four of the nineteen full time qualified fire fighters of the fire department.

J The medical records were reviewed to verify that the fire fighters

!

had current physical examinations. The inspector found that the

!

four fire fighters had current annual physical examinations.

.

c.

Quality Assurance Fire Protection Audits

Section 6.5.3.5 of Technical Specifications requires the licensee to

[

perform fire audits on. an annual, biannual, and triennial intervals.

l The inspector reviewed the results of these fire protection audits

'

and. found that the licensee had performed the required audits in a

,

timely fashion. The audit findings appeared to be thorough.

The quality assurance organization performed the audits adequately with i

the assistance of qualified and independent auditcrs. The inspector considered that the responses of the licentee plant staff to the t

audit findings were adequate and timely.

d.

Fire Protection Equipment i

f The inspector conducted a walkdown of the fire protection systems and equipment in Unit 2 emergency diesel room and 4-KV switchgear

>

rooms, and Unit 3 cable spreading room. Good housekeeping practices were observed in all areas inspected, and combustible materials were

>

properly controlled.

,

i During the walkdown, the inspector requested the surveillance records of the following fire protection equipment:

Pre-actuating detectors for Unit 2 emergency diesel rooms

!

-(biannual)

Diesel driven fire water pump P-220 operability verification i

(annual)

,

Fire detection system for Unit 2 4-Kv switchgear rooms

(biannual)

Actuation detectors for Unit 3 cable spreading room (biannual)

Fire dampers for switchgear 2A Room 308A (every 18 months)

.

Fire doors AC-213, AC-315, and AC-309 (monthly)

l

Alarmed security / fire door AC-246 (biannual)

i

'

Eight-hour discharge test for the following emergency lighting

units (annual):

2XDILBE17 Unit 2 emergency diesel room A 2XDIL8E09 Unit 2 emergency diesel room B

'

0XR3L8E72 Unit 2 4-Kv B switchgear room

'

0XR3L8E38 Unit 2 4-Kv A switchgear room Fire hose stations 553 and 549 (monthly)

The inspector reviewed the surveillance records of these components and determined that the operability for these components was

'

satisfactorily demonstrated at the required frequencies.

In addition, the inspector reviewed the surveillance record, S0123-

'

XV-4.13, " Weekly Inspection for the Control of Combustibles and Transient Fire Loads," for the week ending on October 23, 1993. The l

weekly inspection was adequately documented.

e.

Fire Watches During the walkdown of fire protection equipment, the inspector

interviewed two fire watches at Unit 3, one in the electrical cable tunnel and the other in the auxiliary feedwater pump room.- The

,

inspector evaluated the fire watches' knewledge of their

'

responsibilities and required actions in the event of a fire. The

't fire watches demonstrated adequate knowledge of their duties and i

responsibilities. The inspector also reviewed the two fire watches'

.

log and found the log entries to be adequate.

f.

Information Notice 93-41

.

The NRC issued Information Notice 93-41 to alert licensees to the

\\

results of fire endurance test for Thermal Ceramics Kaowool,

!

Minnesota Mining and Manufacturing Company (3M Company) FS-195, and 3M Company Interam E-50 one-hour fire barrier systems. The

!

inspector reviewed the licensee response to the information notice i

to determine if the fire barrier systems addressed in the notice

were applicable to the licensee's facilities, and, if so, what i

actions were taken to avoid similar problems.

_

.

The licensee informed the inspector that 3M Company Interam E-50

one-hour fire barrier systems were used at San Onofre. The licensee was in the process of identifying the locations and evaluating whether the installations were bounded by the test configuration.

,

The licensee also requested information on the results of additional i

'

tests performed by 3M Company and by other industrial groups. The scheduled completion date was February 1994.

.

The inspector reviewed the licensee's response to this information notice and concluded that the effort completed and planned appeared

_;

i to be adequate.

No violations or deviations of NRC requirements were identified.

(Closed) Violation 50-361. 50-362/89-200-15 Emeroency Diesel Generator Blel Oil Storaae Tank level Calibratinn (92702)

Oriainal NRC Enforcement Item

!

During the 1989 electrical distribution system functional inspection, the team identified inadequate calibration data and procedures for the emergency diesel generator fuel oil storage tank level measurement

,

system, inadequate operator aid data on the quantity of usable fuel oil in the storage tanks, and discrepancies in level setpoints in the system

!

descriptions and operating procedures. The procedure for calibrating the

~

fuel oil storage tank level indicator was insufficient to ensure that the q

storage tank volumes required by the Technical Specifications were being

,

maintained.

Licensee's Actions in Response to the Enforcement Item

i

'

The licensee committed to review the emergency diesel generator fuel oil storage tank level setpoints and calibrations in the overall setpoint

>

reconstitution program. Since the inspection, the licensee completed a revision of the following documents to establish consistency in diesel fuel oil storage tank level setpoints, calibrated span, and. range:

S0123-II-9.245, " GEMS 36000 and 51000 Series TLI System Modular

The high level (LSH) setpoint was set at a level of 136 inches. The low level alarm was set at 125.48 inches. The pump low level cutoff (LSLL)

was set at a level of 11 inches. The calibrated span was at 132 inches.

During the Cycle Six refueling outage, the licensee drained the diesel fuel oil storage tanks for the ten-year inservice inspection. The licensee went into the storage tanks and verified the tank dimension and the accuracy of calculation results. The measured tank dimension was within one-eighth of an inch.

At each calibration of the transmitter for the fuel oil storage tank, the

licensee verified the loop accuracy by doing a sounding measurement of the tank level.

The tank sounding measurements of the actual tank level were within one percent of the indicated level.

The licensee concluded that the instrument loop accuracy of the storage tank level was controlled within one percent of the actual level.

Inspector's Actions Durino the Present Insoection

.

The inspector reviewed the aforementioned revised documents and discussed the adequacy of the calibration of the diesel fuel oil storage tank level indicator with licensee personnel.

,

o Discussion and Conclusion The inspector concluded that the licensee had adequately completed the committed actions. The revised documenets reflected the followings:

The calibration procedure for the emergency diesel fuel oil storage

tank appeared to be adequate.

The operator aid data was consistent with the setpoint calculation.

,

The licensee performed the setpoint calculation conservatively.

• The setpoint list, the system description, and the ' alarm response
