SUMMARY

Scope:

This routine unannounced inspection involved the areas of operations

safety verifica fon, surveillance testing, maintenance activities,

i

re. fueling outage activities, and follow-up on~ previous inspection-

findings.

Results:

In the areas inspected, two violations were identified. One of these

violations was classified as a licensee identified violation (LIV).

The inspection findings indicate a continued weakness in' the

procedural compliance area. A strength was noted in the establish-

ment and use of an on site design angineering staff (see paragraph

11). One unresolved item was identified involving the failure of the

McGuire Safety Review Group (MSRG) to perform the activities intended

by Technical

.ecifications 6.2.3.3 and 6.2.3.4 (see paragraph 8).

Within the ar'eas inspected, the following violations were identified:

-

Inadequate procedure / failure to follow procedure with respect

to safety injection check valve testing (see paragraph 4). This

violation is classified as an LIV.

Unit 1 operated at 100 percent power until June 20 at 12:05 a.m..when

'

the unit tripped on high negative flux rate. The Figh negative flux

rate .was caused when several rods dropped into the core due to a

problem with a rod control cabinet power supply. . The motor generator

minus 24 volt de power supply to one of the rod control ' cabinets -

j

malfunctioned and the other' power supply.to the cabinet from station;

j

auxiliaries was deenergized for a-transfer of power supply from-one

unit to the other.

The problem was corrected and the unit returned

to power operation on June 21.

)

b.

Unit 2 Operations

The unit operated at full power until May 25 wl.en load was gradually

reduced as requested by the load dispatcher and in anticipation of

the scheduled refueling outage.

The unit.was taken off line on

May 27 for a 60 day refueling outage and ended the period with the

i

core off-loaded.

Or: June 24 Unit 2 experienced a short loss of offsite power when

'

real' ming power supplies.

The Unit was in."no mode" at the time

j

with no fuel in the vessel and the the loss of-power had'no effect on

Unit I which was operating at the time. The ?B diesel picked up load

on the bus, however, the 2A di'sel tripped on

a,. v.~rspeed condition

after starting.

This event o: curred on the laet day of the report

period and was still being ir vestigated :by the licensee arid the

inspectors.

No violations or deviations were identified

4.

Surveillance Testing (61726)

Selected surveillance tests were analyzed and/or witnessed by the

inspector to ascertain procedural and performance adequacy and conformance

with applicable Technical Specif; cations.

Selected tests were witnessed to aster *,ain that-current written approved

procedures were available and in use, that test equipment in use was

calibrated, that test prerequisites were met, that system restoration was

completed and test results were adequate.

PT/2/A/4200/09A

ESF Test

a.

ESF-Testing - Unit 2

During performance of ESF testing during the week of May 29,.1988, in

accordance 'with PT/2/A/4200/09A several problems were encountered.

Each time the load shed and. sequencer functioned during the testing.

the feeder breaker 2ECXA ~ opened deenergizing 'several. A train VC/YC-

(control room ventilation and chiller) components.

When manually

closed the breaker operated p'roperly.

Subsequent investigation

-

reveled that the breaker was operating properly and the- sequencer

came out of the accelerated sequence and went into the committed

sequer.ce which is much longer.

Operators were unaware of this-and

closed the-breaker manually prior to it sequencing back on.

Also, train A of Nuclear' Service Water (RN) did not align to .the

low level intake as expected.

The licensee initially suspected

incomplete make up of the actuation switch. IAE later determined that

lifted leads from the switch that had been taped together wepe not

making good contact.

Connecting the lifted leads is ' intentional

to allow the RN portion of the circuitry to align du',g~ the test

_

without adversely affecting other components. The inadq uate contact

prevented RN from realigning. The licensee stated .that .the leads

would be bolted together in the future to provide better contact.

A swing of approximately six- hertz -was noted on- the l 2A diesel

'l

generator output frequency and the test was secured to trouble shoot

the problem.

The governor was replaced and the test was resumed.

The governor was sent to the manuf acturer (Woodward) to detennine the

cause of the failure.

On June 1 the 2A diesel generator did not start on a blackout signal

initiated as part of the test and the test was 'again - secured.

A

relay in the start circuitry was found to be sticking and was

1

'

replaced. Following testing of the' governor the 2A diesel could not

be ' stopped from the control room and had to be shut down locelly.

The licensee discovered that a blackout signal . was initiated and

locked in during the testino of the new governor preventing ~ the

operators from securing the diesel from the control room.

The

procedure for testing the governor is being modified to alert

operators to this. condition.

The A diesel-tripped on overspeed in the next run of the ESF. test due

to a loss of control oil to the new governor. The licensee stated

that the new governor was supplied by Woodward with bolts 1/8"~ longer

than previously installed. This' resulted in.an' insufficient seal . fit

causing a slow loss of. oil.

The licensee' has notified Woodward and

is ' evaluating reportability under: 10CFR21. The governor was again

-

replaced and the A. train of the ESC test .was then completed satis-

factorily.

When testing the B train, B train of .RN failed to align. to the

-

standby Nuclear Service. Water Pond as designed:but did . realign 10

minutes af ter actuation of. the test;

Following 'the test"it was

determined that the taping of ' leads as described above also caused

the problem with B train of RN. During the testing of the B train, a

flange leak developed in the 28 diesel generator lube oil fline which

sprayed oil throughout the 28 diesel ronm.

The diesel was imme-

diately shutdown and clean up and repairs begun.

The licensee

decided to postpone the B train ESF testing to later in the outage in

order to move onto other outage work.'

b.

Safety Injection System (NI) Check Valve Movemant Test

On June 3. 1987, during performance of PT/2/A/4206/09, NI Check Valve

Movement Test, the operating Residual Heat Removal (ND) pump was:left

in service and suction pressure fell 1to zero psi due te.a decrease in

loop water level when. the other ND pump was started for the test.

One N0 oump was secured and suction pressure returned to normal. The

test was completed successfully.

The licensee investigated the

occurrence and found the procedure to oe inadequate in many respects

including the fact that the test procedure did not directly monitor

reactor coolant level or ND suction pressure. Also, a note contained

in the procedure stated that valves may be aligned by;the- operating

procedure (0P). This was meant to allow the valvessto be signed off

as being in the position required by the PT af ter verifyina that they

were in that position by reviewing the OP.

Instead, operators

interpreted tne statement to niean ' that valves ceuld be in the

position required by the PT or the OP. .Two valves were in positiots

not in compliance with the PT due to this erroneous interpretation

The licensee is changing the performance +.est to correct these :and

other deficiencies. These deficiencies are identified as a -licensee

d

identified violation (LIV 370/88-14-01) for an inadequate procedure

(PT/2/A/4206/09) and failure to follow the procedure with regard to

misinterpretation of the valve alignment requirements.

The selected activities witnessed were examined to-ascertain that, where

applicable, current written: approved procedures were available and in use,

that prerequisites were. met, that equipment restoration was; completed and

maintenance results were adequate.

On May 23, 1988, during performance of PT/2/A/4200/36A,.DG.2A-24 Hour Rm

Lthe diesel could only :be loaded to 4375 KW. The procedure required _.4,,

KW

0perations requested ' maintenance ' adjust the diesel . engine to provide

the required. output but no -work request was initiated as required by-

Maintenance Management Procedure 1.0.

Maintenance personnelLadjusted the

-fuel racks to obtain an output of 4400.KW without a work request and-

without a procedure. TS 6.8.1.in conjunction with Regulatory 1 Guide 1.33 .

require that maintenance which can af fect performance of- safety-related

equipment be performed -in accordance with written procedures. 'This is

identified as an apparent violation (370/88-14-02) for a failure to follow

procedure and a failure to have a procedure.

The inspector also noted

that the diesel ' vendor manual states tnat' the fuel pump rack? settings

should be equal at all pumps. This condition is mt satisfied if adjust-

'

ments similar to those made on May 23 are' performed.

During an NRC senior management .oaeting in - June .1987, it was

concluded that additional i n forma'.i on was needed regarding the

.

overall performance of Duke Power Company and its nuclear stations.

.The McGuire Nuclear Station was chosen for the '"diagnostic evalua-

tion" of Duke's nuclear program.

On November 20, 1987, a Diagnostic Evaluation Team' (DET) began an

initial two-week evalntion at the station and corporate' offices.

Selected team members returned.:to the Duke Corporate. offices on

January 4,1988, for an additional ' week . to complete the evaluation.

An exit' meeting with corporate officers and managers was held on

January 22, 1988 at the Duke corporate of fices in Charlotte, North

Carolina.

The Diagnostic Evaluation Team report was transmitted to the licensee

on April 8,

1988.

One of the findings. documented in the : report -

concerned the McGuire Safety Review' Group (MSRG).

Specifically, it

was determined that:

(1) the MSRG had not been . performing all

functions identified as part of .the McGuire licensing basis and

resultantly did not appear to have.-been.meetir.;: the intent.of McGuire

TS 6.2. 3. 3 a'nd 6.2. 3.4 (2) the scope and focus of current- MSRG

activities had evolved to the point:that the majority of the group's.

time was spent on investigation- of. plant ~ events, with little or

no time spent on surveillance of plant operations and maintenance

activities, and (3) a proposed TS change increasing MSRG responsi-

bility for review of' written safety evaluations could further-

adversely effect MSRG review functions.

'

With respect to licensing basis commitments, it was found that

certain of the functions. described in the ' Safety Evaluation Report

(SER) for McGuire were not being performed by- the MSRG

The MSRG was

not reviewing: (1) all design changes involving structures, systems,

or components, nor (2) all station. procedures and changes to

procedures. Discussions with the Nuclear. Safety Review: Board (NSRB)

.

l

Director confirmed the team's observation,

Supplement No. 4 to tht SER for McGuire documents NRC staff review

of the MSRG.

The review discusses the acceptability of the MSRG

as described by Duke in Station Directive 3.1.32, ."Station Safety

Engineering Group." The SER stat'ed that the MFRG will function as '

an independent technical review group in the performance of the '

l

following activities:

(1) Review of LERs for applicability to McGuire.

(2) Review and evaluate the effectiveness of plant programs.

(3) Review of all design changes involving structures, systems, or

components with quality assurance conditions to insure all

safety concerns are properly addressed.

determine their adequacy.

'

'

(5)

Investigate all incident reports. involving reportable items'and

'

conduct other. investigations as deemed . appropriate bye the MSRG

Chairman.

The SER assumed that the LStation' Directive 3.'1.32 would be approve'd'

and implemented prior to fuel load'of.McGuire Unit 1.

This was never

approved or implemented.

On January 6,1981, however, the licensee provided a response -to TMI

Actions Items I.B.1.2 and I . C .' 5 .

As part ~ of this ' response, the'

licensee provided the charter of the MSRG. This charter is'signifi-

-

cantly different from Station Directiv_e 3.1.32.

As an example,

neither functior. (3) nor (4) described above was contained 'in the

charter.

The MSRG Chairman indicated in an interview that recent activities of

.

the review group result in 85-90 percent of their time being devoted

to incident investigations. A review of the SRG Work Assignment Log-

-

covering the year 1987 indicated that no routine station activity

areas had been assigned to any MSRG member during 1987.

.0NRR Review

A review of the above menti aed findings of th'e!DET was performed.by

0NRR staff. Tne thrust of that review dealt with the-history:of the

commitments made by the licensee ' relative' to the MSRG. , The L ONRR

review confirmed th inconsistencies described above and

revealed

that these inconsistencies are-the probable result of.the time frame

of .the McGuire NT0L review. ;Spe:1fically item I.B.1'.2 of NUREG-06601

(May 1980) with respect to the '/ndependent Safety Evaluation Group .

.

(ISEG).had not been clearly develemd at-_that. time.

Item I.B;1.2 of

NUREG-0757 (November 1980) later described the. ISEG as a functional

entity with prescribed functions. Station 0irective. 3.1.32, the SSRGJ

Charter, and finally the McGuire Technical . . Specification parallel

staff development'of the ISEG.- The'ONRR review concludes that the.

~

MSRG, 'as required by Section 6.2.3 ~ of . the McGuire Technical

Specifications, reflects' the staff's current _ position as'shown in'the

corresponding section of the ' Standard Technical Spect fications1(STS) ~

dated August 6, 1981.

Based on a review of the references-listed earDer and discussions

~

with ONRR and RII staff, the resident' staff redew was ~ refocused

to deal exclusively'with MSRG compliance ' with applicable . Technical

Specifications.

Discussions .with the MSRG chaiman, review of the. SRG Work Assignment

Log covering the period of 1986.through the present, .and review of

~

the Inplant Reviews conducted by the MSRG during that time, led to

~

the following conclusions:

(1) The majority of the MSRG's time is .. spent generating incident

investigation reports (IIR).

The Work Assignment Log revealed

.

that during the period 1986

present, 203 :IIRs' were generated'

j

but only 15 inplant reviews were - performed (inplant reviews

1

are independent reviews. of station- activities, and are ' not

j

necessarily coupled with IIRs; these. come closer .to' meeting

what was intended by TMI action item I.B.1.2).1This reveals.that.

93% of the MSRG's ef forts were devoted to. the generation of'

IIRs.

(2) Other than - those reviev;d in the course of pctforming a'n

h

incident ' investigation, procedures are not reviewed program-

matically to determine adequacy.

(3) Other than those reviewed in the course of' performing , an

j

incident investigation, de,1,1n changes are not programmatically

reviewed to insure all suety concerns are properly andressed.

Ultimately, technical specification 6.2.3. Station - Safety ' Review

Group, 1s the culmination of the-negotiations of commitments-relative

to TMI . Action Item I .B.1.2.

To reiterate, the intent -of an ISEG

.(MSRG) is . to examine plant operating- characteri stics, NRC issuances, -

Licensing Information Service adviso. ries,. Licensee. Event Reports, and

other appropriate sources which may indicate-areas for ~ improving.

plant safety.

It is expected that this group develop detailed.~

recommendations for revised procedures, equipment modifications, :or

other means of achieving the goal .of improved plant Lsafety.

A'

principal function of the independent safety engineering group is to

maintain surveillance of plant operations and maintenance activicies

to provide independent verification that these activities . are

performed correctly and . that human errors are reduced as far as :

practical.

These fi.1 dings were~ discussed. with the NSRB and ' MSRG

Chairmen on June 13, 1988. . The NSRB Chairman indicated that the

current-operation of the SRG's at the Duke facilities were patterned

after the description of an ISEG as. described in NUREG 0800, Standard

Review Plan, (SRP) Section 13-4. , .and that the resident's findings

.

were a redefinition of the requirements.

A subsequer.t review of that section of the SRP confirmed the

following-

(1) The -ISEG is to perform ' independent reviews of plant operations

in accordance with the guidelines of item I.B.1.2 of NUREG-0660

and NUREG-0737.

(2) The group is to function to examine plant operating character-

tstics, NRC issuances, Licensing-Information Service advisories,

and other appropriate - sources of ' lant design and. oper_ating

p

experience information fo'r areas to impro've plant. safety; and

to perform surveillance of plant operations and -maintenance

activities to provide independent verification that . these

activities are performed correctly and that h' man ' errors 'are

-

u

,

reduced as far as practicable,

j

(3) The group is to perform independent reviews and audits of plant

activities including maintenance, modifications, operational

.

problems, and operational analysis, and aid'in the establishment

of programmatic requirements for plant activities.

Based on the resident inspection staff review, it is concluded that

the intent of technical specifications 6.2.3.3 and 6.2.3.4 are not

being met by the current operation of the MSRG. A meeting is-going

to be held to discuss this issue.with licensee and NRC management.

This is unresolved item (50-369,370/88-14-03) pending . review and -

results of the meeting.

Fisher Valve Problems

On June. 19', 1988, +.he inspectors became aware of a concern with the design:

.of pre-1977 air : operated Fisher Valves.

Apparently Fisher did not

consider p'acking; and seating' loads for sizing of valve springs ~ prior to

1977. The. significance of the concern is that the Fisher Valves used in

safety related ~ applications may-not go to their safe positions-on a loss

of air under. design basis conditions.

The licensee'is evaluating.and/orL

testing all active Fisher . Valves :in this Jcategory.

The licensee has

stated that problems- with Fisher' Valves failing to: go to _ their safe

positions have not been identified in ' the . plants' hi story.

Licensee-

personnel were working with Fisher to: develop means of. testing the actual-

packing loads on the valves in question.

This issue was still -under

review at the end of the inspection period.

10. -Refueling Activities (60710)

Unit 2 commenced . its End-of-Cycle' 4 refueling outage on May 27.

The

outage is scheduled to last 60 days.

Preparations and refueling activities were observed and monitored to

ascertain whether-Technical Specification requirements were satisfied and

activities were conducted in accordance with approved procedures.

Portions of the following activities were observed:

-

Core Off Loading

-

Ultrasonic Inspectiot, of Fuel Pins

-

Control Rod Inspection

No violations or deviations were identified.

11.

Design Engineering On Site Support

The licensee completed staf fing of a design engineering group on site in

mid May of this year.

The on site group consists of 5 design' engineers

and a supervisor.

On site support is intended to strengthen engineering

review and evaluation of problems which arise.

This group has been of

benefit in evaluating issues such as the Fisher valve problem described in

this report.

The inspectors consider -the presence of an on site design

staff to be a strength.

Exit Interview (30703)

The inspection findings identified below were summarized on June 24, 1988,

with those persons-indicated in paragraph 1 above.
