DETAILS

1. Persons Contacted

J. Driscoll, Assistant General Manager - Salem Operations

L. Fry, Operations Manager

J. Gallagher, Maintenance Manager

H. Midura, General Manager - Salem Operations

L. Miller, Technical Manager

J. O'Connor, Radiation Protection Engineer

F. Schnarr, Reactor Engineer

R. Silverio, Assistant to the General Manager

J. Stillman, Station QA Engineer

The inspector also interviewed other licensee personnel during the course

of the inspections including management, clerical, maintenance, operations,

perfonnance and quality assurance personnel.

2. Status of Previous Inspection Items

(Closed) Unresolved Item (311/81-25-03) Diesel support systems opera-

bility. The inspector reviewed Operations Directive 12, dated

February 4, 1982 which provides detailed guidance to operators

relating to the length of time the pre-lubrication pump can

be inoperable without impacting on operability of the diesels.

Additional guidance for periodic operation of the engine to

maintain temperatures under these conditions is also provided.

The licensee is further evaluating the impact, if any, of

inoperable jacket water heaters. The inspector had no fµrther

questions on this item.

(Closed) Unresolved Item (272/80-32-01) Tennination criteria for charging

pump following a steamline break (reference IE Bulletin 80-18).

The licensee has modified the isolation logic for mini-flow

valves 1CV139 and 1CV140 such that the valves will not shut on

initiation of safety injection, thus affording a recirculation

flow path in the event the reactor coolant system does not

depressurize.

Emergency instructions have been modified to

alert the operator to shut the valves if pressure drops to 1500

psig. Manual safety injection testing has confirmed that the

valves will stay open. Operators interviewed were aware of

the change in control design.

The inspector had no further

questions on this item.

(Closed) Unresolved Item (311/81-11-04) Pressure boundary isolation

valve testing. The inspector reviewed the completed test

results for procedure SP(O) 4.4.7.2.2, Emergency Core Cooling.

This procedure measures leak rate through isolation valves

which separate the reactor coolant system from lower pressure

injection systems.

3

Results of this testing were documented in NRC Inspection Report

50-311/81-11. All leakage, including multiple valve tests, was

less than 1 gallon per minute. License DPR-75, condition 2.C.

(15)(c), allows multiple valve testing until the first refueling

outage with acceptance criteria given as l.gpm for single valves,

2 gpm for two parallel valves, and 3 gpm for three parallel valves.

These acceptance criteria are in the licensee's procedure~.

Several retests as a result of flow due to inadvertent safety

injections are also documented.

The inspector had no further

questions on this-item.

(Closed) Unresolved Item (272/81-14-05} Calibration of flow meter used

for boundary check valve leak rate testing. The above testing

used installed mechanical leak detectors which are graduated in

gallons per minute in two scales; 0-1 and 0-10 gpm.

Since the

devices were not originally intended for application as quanti-

tative leak measuring devices, no certification of accuracy or

in-place calibration capability was provided.

The inspector

reviewed results of single point calibration checks conducted

on March 27 and 29, 1982 which validated the accuracy at 1.0

gpm for the low scale and 1.95 gpm for the high scale. Since

these verification points are considerably in excess of the

measured values, confonnance to the Technical Specification

acceptan*ce criteria was demonstrated.

The 1 icensee stated that

the-flow devices will be replaced or supplemented by more readily

verifiable instruments.

The inspector had no further questions

on this item.

(Closed}

Follow Item (272/80-20-05} Annual employee training. The in-

spector, based on interviews with station personnel and regional

inspectors' input, confinned that the licensee is providing

adequate indoctrination in the use of radiation exposure permits

and applicable exposure limits.

(Closedl Follow Item (272/81-14-02} Completion of modifications to

mitigate instrument bus failures.

By inspection of instrument

power distribution panels and review of design change documen-

tation, the inspector confirmed that the distribution changes

for diesel generator, auxiliary feedwater, and steam generator

level indications had been completed as stated in the response

to IE Bulletin 79-27. Modifications to Unit 2 are scheduled for

the first refueling outage.

Review of Plant Operations

A.

Daily Inspection _

The inspector toured the control room area-to verify proper manning,

access control, adherence to approved procedures, and compliance with

LCOs.

Instrumentation and recorder traces were observed. Status of

control room annunciators was reviewed.

Nuclear instrument panels

and other reactor protective systems were examined.

Control rod in-

sertion limits were verified. Containment temperature and pressure

indications were checked against Technical Specifications. Effluent

monitors were reviewed for indications of releases. Panel indications

for onsite/offsite emergency power sources were examined for automatic

operability. During entry to and egress from the protected area, the

inspector observed access control, security boundary integrity, search

activities, escorting, badging, and availability of radiation monitoring

equipment.

The inspector reviewed shift supervisor, control room, and field

operator logs covering the entire inspection period. Sampling reviews

were made of tagging requests, night orders, the jumper/bypass log,

incident reports, and QA nonconfonnance reports.

The inspector also

observed several shift turnovers during the period.

The above daily inspections, which included back shifts, were made on

March 9-12, 15-19, 22-27, 29-31, April 1, 2, and 5.

No unacceptable conditions were identified.

B.

Plant Tours

The inspector toured accessible areas of the plant at least once per

week.

The tours included the control rooms, relay rooms, switchgear

rooms, penetration areas, auxiliary building (elevations 122', 100',

84', 64', 55'}, fuel handling building, turbine building, service

water intake structure, plant perimeter and containment. During these

tours, observations were made relative to equipment condition, fire

hazards, fire protection, adherence to procedures, radiological con-

trols and conditions, housekeeping, security, tagging of equipment,

ongoing maintenance and surveillance, and availability of redundant

equipment.

5

Operability of the following Unit 2 ESF subsystems was verified by

confirming flowpath valve positions, breaker alignment, instrumen-

tation and equipment condition,;: Containment Spray (both trains -

Auxiliary Building), Auxiliary Feedwater (3 trains - Auxiliary

Building and Penetrations), Safety Injection (both trains - Yard,

Auxiliary Building and Penetrations), Service Water (both trains -

Yard, Auxiliary Building). Current tagouts of the Unit 1 Auxiliary

Feedwater System, Safety Injection System and a portion of the RHR

system were verified in effect as specified. Records of current

surveillance for tank boron concentrations, shutdown margin and pump

testing were reviewed.

The inspector conducted a complete walkdown

of the Safety Injection system, to examine conformance with as-built

drawings, lineups, supports, instrumentation, electrical and controls

cabinets and to confinn availability of the system.

The following Limiting Conditions for Operation, not directly verifi-

able in the control room, were confirmed by field inspection or record

review;:* service water availability to Auxiliary Feedwater (3.7.1.3),

Fire barriers (3.7.11), Diesel fuel inventory (3.8.1.1), and CARDOX

system availability (3.7.10.3).

The inspector witnessed selected portions of radioactive liquid and

gaseous *releases to confirm procedure adherence, approvals, sampling

and instrumentation. The following release was observed;* l-_LL-054-82

(11 CVCMT on March 25, 1982). Post-release documentation for release

l-LL-058-82 (.12 CVCMT on March 31, 1982) was also reviewed.

During these plant tours, minor problems associated with unsecured

compressed gas bottles, apparent fire hazards, and poor housekeeping

were identified and were discussed with facility management.

In

addition, several instances of fire doors left or blocked open with

no evident compensatory fire watches or patrols were identified.

This issue is detailed in NRC Inspection Report 50-272/82-06 as an

apparent violation.

While verifying tagouts on a plant tour on March 15, the inspector

noted that the motor breaker for valve 2 RH 26 was in the

110ff

11

position with a red danger tag applied.

The tag, generated for tag-

. out number 3875, was prepared for valve 1 RH 26, but had been applied

to the corresponding breaker in Unit 2. 2 RH 26 is the RHR discharge

valve to the hot legs and is opened well into the recirculation phase

following an accident. Technical Specifications for both units

require that the valve be kept shut with motive power removed during

operation.

Power is removed by means of lockout switches in the

respective control rooms. Therefore, turning the breaker off and

applying the tag did not prevent safety system function in Unit 2.

However, applying the tag to the wrong valve contributes to non-

compliance with Technical Specification 6.8.1 and station Administra-

tive Procedure AP-15.

6

WhH>e observing maintenance on the 12 Safety Injection ff.:ump, the

inspector noted the lack of blocking tags on the suction and alternate

suction isolation valves, 12SJ30 and 11SJ45 respectively~ To perform

the maintenance the component had to be isolated. It was determined

that the breakers for the valves' motor operators had been properly

tagged but the handwheel operators had not been tagged to prevent

local manual operation. Thus,_ isolation of the component was not

assured. Station Administrative Procedure, AP-15, requires that the

supervisor in charge of the work confirm complete isolation of equip-

ment prior to starting work.

In aggregate these two violations of

tagging requirements constitute a violation of Technical Specification 6.8.1 l272/82-05-01)(311/82-08-0l).

A tour of.the yard area identified an additional tagging problem

involving valves 11LW16 and 12LW16; a valid tagging request was filed

in the control room to keep the valves closed but no tags were in

place. These valves isolate the liquid waste discharge from the Unit

1 circulating water system which is shut down during the outage. The

valves were, in fact, closed and are verified closed prior to each

radioactive liquid discharge.

The licensee postulated that, since

the valves are outdoors, the tags were lost due to weather. They

were placed on January 6, 1982. The tags were replaced.

The inspector had no further questions relative to observations during

plant tours.

4.

Review of Periodic and Special Reports .

Upon receipt, periodic and special reports submitted by the licensee

pursuant to Technical Specifications 6.9.1 and 6.9.2 were reviewed by

the inspector.

The reports were reviewed to detennine that the report

included the required information; 0that test results and/or supporting*

information were consistent with design predictions and performance

specifications; that* planned corrective action was adequate for resolu-

tion of identified problems; and, whether any information in the report

should be classified as an abnormal occurrence.

The following periodic and special reports were reviewed:

Unit 1 Monthly Operating Report - February 1982

Unit 2 Monthly Operating Report - February 1982

Safety Evaluation of the PSE&G Rod Exchange Measurement Procedure

dated February 2, 1982

Salem Unit 2 Startup Report - 10% to 100% Power Range Testing

dated February 2, 1982

7

No unacceptable items were identified. The rod exchange procedure is

undergoing additional staff review by NRC Region I and NRR.

However,

use of this method during cycle 4 is acceptable.

5.

Training

The inspector examined several aspects of licensee training programs,

including licensed operator requalification training, effectiveness of

employee orientation, and training of contractor personnel.

To confirm adherence to procedures and commitments, the inspector

attended one operator requalification class dealing with recent operating

plant events, interviewed recently hired temporary employees, and re-

viewed selected records of training for maintenance contractor super-

visors.

With respect to licensed training, the inspector confirmed that the class

attended was consistent with the program and schedule outlined and met

the objectives specified. With respect to employee indoctrination, the

inspector confirmed, within the scope of review, that employees received

instruction, consistent with their function and responsibility, in

administrative procedures, quality assurance, radiation protection,

safety and security, and emergency plan procedures.

No unacceptable conditions were identified.

6.

Maintenance Activities

The inspector observed portions of maintenance activities to determine

that the work was conducted in accordance with approved procedures,

regulatory guides, Technical Specifications, and industry codes or

standards.

The following items were considered during this review:

limiting conditions for operation were met while components or systems

were removed from service; approvals were obtained prior to initiating

the work; activities were accomplished using approved procedures and

were inspected as applicable; functional testing was performed prior to

declaring that particular component as operable; activities were

accomplished by qualified personnel; radiological controls were imple-

mented; and fire prevention controls were implemented.

Activities observed included:

No. 12 Safety Injection Pump - Failed pump seal

No. 2 Fire Pump - Failed to operate

Solid State Protection System - Faulty sequence indication

No. 11 Charging Pump - Replaced speed changer

No. 22 RHR Pump Motor - Failed to operate

8

With respect to the maintenance on the No. 22.H!tR pump motor, the licen$ee

perfonned troubleshooting activities after Jts,.fai*lure during a functfonal'

test on April 2, 1982.

The motor had tripped twice -oh overcurrent; 6ITT:e

on the

11A

11 phase and once on the

11 C" phase. After investigating the

problem, the licensee replaced the tenninal leads on the motor which

evidenced some minor fraying.

No other problem was indicated. The pump

then passed a functional test and was declared operable.

In discussions

with the resident inspectors the licensee agreed to perfonn increased

surveillance on this component (daily for several days, weekly for the

next 3 weeks} to assure that the problem was identified and corrected.

At the end of the report period the pump-had been started on three occa-

sions without tripping.

7. Surveillance Testing.

The inspector observed the perfonnance of surveillance tests to confinn

the following:

testing was performed in accordance with adequate pro-

cedures; test instrumentation was calibrated; limiting conditions for

operations were met; removal and restoration of the affected components

were properly accomplished; test results conformed with Technical Specifi-

cation and procedural requirements and were reviewed by personnel other

than the individual performing the test; deficiencies noted were reviewed ..

and appropriately resolved; personnel performing the surveillance activities

were knowledgeable of the systems and the test procedures and were qualified

to perform the tests.

These observations included:

SP(FF} 4.7.10.1.1.f, Fire Pump Functional Test, Revision 5, dated

September 15, 1980

2 PD 4.2.064, Channel Functional Test 2R41A, Plant Vent Particulate

Process Monitor, Revision 1, dated September 26, 1980

The inspector also reviewed the results of Surveillance Procedure SP(O)

4.5.2H, Throttling Valve Flow Balance Verification, which demonstrates

charging and safety injection pump flow rates and establishes throttle

valve positions for flow distribution to the four loops. Valve positions

were recorded and the valve stems marked.

The inspector had no questions regarding the performance of surveillance

activities.

..

8~ Procurement

The inspector toured the licensee's Warehouse and Storeroom to confirm

that storage of safety related material and spare parts conformed to

procedure.

The inspection included verification of receipt inspection

by qualified personnel, storage in accordance with defined requirements,

applicable preventive maintenance, traceability to purchase order and

part definition, and appropriate consideration for shelf life.

With respect to shelf life items, the licensee has instituted a periodic

review through the Inspection Order system to require inspection of

shelf life perishable items and to remove those items which are dated.

However, no list of such items has been prepared. Stock room personnel

conducting this review acknowledged only reagent chemicals as being in

this category.

As a result, only chemicals, which are stored separately,

are reviewed for dating. The inspector inquired about two-part penetra-

tion sealant kits (Sem-kits) which also carry expiration dates. The

items were located in the warehouse and had an expiration date of July

1982.

The licensee acknowledged that these items would not have been

detected by the present system. Further, no other items had been so

designated, including valve diaphragms which carried stamped 1975 dates.

One vendor has provided a 5 year shelf life for diaphragms.

The licensee

stated that tbe system will be modified to include other items which may

be identified as having a defined shelf life. This item is unresolved

penging further review of time sensitive items by the inspector (272/82-

05-02).

9. Audit Program

The inspector examined several aspects of the licensee's Quality Assurance

audit program, including frequency, reports, followup, responsiveness,

independence, and qualifications of auditors. This examination included

observation of an audit in progress and review of recently completed audit

reports.

A QA Department audit of nuclear training, conducted on behalf of the

Nuclear Review Board, was observed during the period March 15-19. The

inspector attended the entrance and exit interviews and periodically

observed the auditors. The inspector also reviewed follow up documentation

from 1981 audits of training, administration and design changes.*

Within the scope of this review, the inspector found that audit scope was

adequately defined and followed, that appropriate followup and escalation,

when necessary, were conducted.

With respect to qualification of auditors,

the licensee stated that the auditors were qualified as required by ANSI

N45.2.12 and N45.2.23.

The records and certifications are maintained at

tha corporate office. These certifications address qualification ~s an

auditor but do not provide evidence of requisite experience and training

commensurate with the complexity of the activity being audited. Qualifi-

.cation records and auditor selection criteria will be examined during a

subsequent inspection at the corporate office (272/82-05-03).

10. Licensee Events

a.

In Office Review of Licensee Event Reports

The inspector reviewed LERs submitted to the NRC:RI office to verify

that details of the event were clearly reported, including the

accuracy of the description of cause and adequacy of corrective

action.

The inspector determined whether further information was

required from the licensee, whether generic implications were in-

volved, and whether the event warranted onsite followup.

The

following LERs were reviewed:

b. Onsite Licensee Event Followup

For those LERs selected for onsite followup (denoted by.asterisks

in detail paragraphlO~, the inspector verified the reporting

requirements of Technical Specifications and Regulatory Guide 1.16

had been met, that appropriate corrective action had been taken,

that the event was reviewed by the licensee as required by AP-4

and 6, and that continued operation of the facility was conducted

in accordance with Technical Specification limits. The following

findings relate to* the LERs reviewed on site:

UNIT 1

--

82-07 /01 T

--

82-08/03L

--

82-09/03L

--

82-10/03L

This event is discussed in NRC Inspection Report

50-272/82-06.

The inspector confirmed that modifi-

cations to account for the postulated loss of

auxiliary feedwater have been made in both units.

The modifications consist of a support and shield

for the piping and check valves mounted from the

seismic auxiliary building wall.

The structural

steel enclosure and trench location of the valve

provide adequate protection from seismically

induced debris.

The inspector had no further

questions.

The report contends that dilution of the boric acid

tanks resulted from a non-repetitive evolution;

refilling following maintenance.

The inspector,

in reviewing operating procedures for filling these

tanks, concluded that established routine procedures

existed which should have precluded dilution. The

licensee is investigating the sequence of events

further and will submit a supplemental report. ThiS

item is unresolved (272/82-05-Q4). -

For the safety of personnel working in CARDOX-

protected areas during the refueling outage, the

system was placed in the manual mode.

Appropriate

fire watches were stationed and the systems will be

returned to automatic when outage work is completed

and the rooms no longer routinely occupied.

This event is detailed in NRC Inspection Report

50-272/82-01. The temporary hose is no longer in

service. The inspector confirmed that the temporary

connection had been properly reviewed and approved

by SORC.

The safety analysis bounded the loss of

water and radiological significance actually observed

during this failure. The inspector had no further

questions.

This fire alarm failure affected only the audible

alarm sounded on the plant page system.

Detectors

remained operable and provided visual alar.ms.

The

licensee posted a watch at the annunciator panel

to ensure timely response by the fire brigade.

Valve 22SW223 was freed by exercising to restore

operability of CFCU 22 on January 28, 1982. A

subsequent failure to achieve required flow on

March 4 was attributed to the same valve and will

be reported in a subsequent LER.

Following the

later problem, the valve was disassembled and the

valve bushing found to be seized.

The valve was

repaired and tested satisfactorily.

Comments above with respect to Unit 1 LER 82-07

apply to this report as well.

The inspector witnessed portions of the trouble-

shooting and repair of Overpower Delta T Channel 21.

No unacceptable conditions were identified.

Following receipt of an Air Particulate Detector

Pump Low Flow alarm, valve 2VC908 in the suction

line to the detector was found partially closed.

Subsequent investigation by the inspector revealed

that a containment atmosphere sample had been taken

shortly before the low flow alarm came up.

The

sample procedure requires insertion of the sample

holder in a bypass loop and, throttling of valve

2VC908 to obtain 20 to 30 ~/min flow through the

sample rig. Although the procedure specifically

calls for fully opening the valve following sampling,

this was apparently not done. Additional counseling.

of individuals involved, memorandum notification

to all sampling personnel, and procedural addition

of a specific caution have been accomplished to

prevent recurrence.

The inspector had no further

questions.

This event is discussed in NRC Inspection Report

50-311/82-01.

On February 9, 1982 Steam Generator 21 Level Channel

2 went high for a period of less than five minutes

and returned to normal indication. Since this is

the controlling channel, the feedwater system was

placed in manual and returned to automatic after

normal indication was restored. Lacking a distinct

failure, the channel remained in service while

monitoring instrumentation was connected to evaluate

performance. Analysis of recorder traces led to an

initial conclusion that the transmitter had failed.

The channel was tripped at 11:10 p.m. when this

conclusion was reached.

Replacement of the t~ans

mitter did not resolve the problem, which was later

traced to a shield double ground.

Once the shield

ground was lifted, no further problems with the channel

were noted.

This event is detailed in NRC Inspection Report 50-

311/82-05.

The inspector had no further questions relative to LERs reviewed during

this report period.

11. Operating Events

UNIT 1

The plant remained in Mode 5 (Cold Shutdown} through most of the report

period, with outage work being completed.

On April 3, Mode 4 was

achieved at 10:00 p.m.

Mode 3 (Hot Standby} was entered at 4:20 a.m.

on April 5 with about one week scheduled for testing and work completion

prior to criticality.

Three events were reported to NRC via the Emergency Notification System

during the report period:

At 8:24 p.m. on March 14, with the lA Vital 4 KV bus already out

of service for maintenance, surveillance testing of the

11C

11 Safe-

guards Equipment Cabinet (SEC) resulted in initiation of a station

blackout signal and loss of all Vital 4 KV busses.

lB and lC

diesel generators started and loaded as designed to pick up loads

of the two available vital busses.

Nonnal shutdown electrical

alignment was restored by 8:31 p.m.

At approximately 6:00 p.m. on March 18, operator inspection iden-

tified a service water leak in containment. The flange and packing

on valve 11SW65 were leaking about 1 gpm.

The leak was isolated

and repaired. The plant was in Mode 5 with no requirement for

containment integrity.

UNIT 2

14

At about 11:00 p.m. on April 3, visual inspection identified a

containment service water leak from the flange of valve 14SW65.

Containment Fan Coil Unit (CFCU) 14 was isolated and the leak

repaired by tightening flange bolts. Leak rate was about 0.5 gpm.

The unit operated at full power for almost the entire period with no trips

and no events requiring one-hour notification of NRC.

Power reductions
