enerators

This item related to an apparent failure to incorporate

conclusions

from a design calculation into applicable

procedures,

which resulted in the

Emergency Diesel Generator

(EDG) air start system not being aligned

as required to perform

its design function under all conditions

assumed

in the Final

Safety Analysis Report

(FSAR).

Design calculation

13-MC-ZZ-704

and Engineering Evaluation

Request

(EER) 86-XM-046 had

determ)ned that the

XCV isolation valves

needed to be closed to

meet these

design criteria.

The licensee's

immediate

corrective action was to align the

XCV isolation valves per

EER

86-XM-046.

Further review of the circumstances

by the licensee

determined

that the results of the calculation

and additional information

derived from field testing

had been incorporated into

appropriate

procedures,

but that

a misinterpretation of the

design criteria had occurred.

The licensee's

engineering staff

incorrectly assumed that the system's

two air receivers

together,

rather than each,

were to have sufficient capacity to

start the

EDG five times.

This error resulted in erroneous

conclusions

being incorporated into the procedures.

A major effort which should identify such deficiencies

in all

safety

systems

is the design basis reconstitution.

To prevent

recurrence,

all Nuclear Engineering

Departments

and Engineering

Evaluations

Department

engineers

and supervisors

have

been

instructed via memoranda of the necessity of ensuring design

criteria are fully understood

in dispositioning applicable

documents

and that disposition information is correctly

incorporated within applicable

implementing documents.

The inspector

concluded that licensee

actions

were

satisfactory.

During observation of Unit 2 defueling activities from the

refuelinq machine,

the inspector

noted that

a grapple limit

switch dsd not consistently function to activate indication of

grapple

engagement.

However, operators visually verified

grapple position by confirming the position of the manual

operator

and the inspector

concluded that this provided

adequate

assurance

of grapple position.

The inspectors

observed

maintenance

on the Unit 2 emergency

diesel

generator

on Harch 8, 1990, in which mechanical

maintenance

personnel

were repairing

a minor fuel oil leak on

an injector.

When loosening

a set screw,

the screw fell out

and fuel oil flowed to the floor of the room.

The on-shift

personnel

took proper actions to limit the oil spill to an area

of about four square feet and they properly cleaned

up the

s pi 1 l.

The inspector

observed

performance of maintenance

procedure

32NT-9Z234 on

a spare

4160 Volt circuit breaker.

The inspector

verified that properly calibrated test equipment

was

used, that

the electricians

had

a current and properly approved procedure

and that they were following the procedure

in a step-by-step

fashion.

The inspector

observed

the refurbishment of the "B" diesel

generator

"A" air intercooler.

Portions of the cooler

.including the

end plate seating surfaces,

had been coated with

a ceramic material.

Because this materia'I

was applied unevenly

on what is required to be

a machined surface,

substantial

rework was required.

Additionally, the licensee

is

reevaluating

the

use of this material

and the method of

application,

based

on this less

than satisfactory

experience.

Unit 3

Oescri tion

o

Valve RC-207 Packing

Leak

o

MSIV 4-way Valve Replacement

The inspector

reviewed the licensee's

analysis to,install

two

oversized

packing gland nuts

and spacers

over the existing nuts

on a 3/4 inch Borg Marner globe valve used

as

an instrument

isolation valve on the pressurizer.

The licensee

had

previously used injected material to stop

a packing leak, but

had not been successful

and had further determined that one

existing gland nut was galled and could not be taken

down any

further.

The licensee

chose the oversized

gland nut and spacer

combination

as

a means to further compress. the packing and

injected material.

Prior to performing this work,

NRC inspectors

questioned

the

adequacy of the

MNCR 90-RC-0009 Conditional

Release

engineering

analysis

on two points.

The first was the lack of an analysis

of the stress

on the packing gland retainer

due to the spacers.

Subsequently,

the licensee

determined that the retainer could

withstand this stress.

Second

was the lack of a stress

analysis

on the pin which secures

the packing gland stud to the

10

valve body.

In this case,

the licensee

was preparing to use

a

planned

nut torque of 75 ft-lbs which would have

exceeded

the

allowable stress

on the pin.

Following the inspector's

questions,

the licensee

modified the work order to reduce the

maximum allowed torque value to 30 ft-lbs, which was consistent

with the manufacturer's

recommendations.

The use of the

75

ft-lbs value

was based

on apparent

misunderstanding

of the

MNRC

analysis

which appeared

to allow the

use of this

maximum value.

The inspector concluded that the licensee

was preparing to

proceed with this work order

(WO 00419787) without an adequate

technical

basis for the use of 75 ft-lbs of torque.

The

MNCR

analysis

which appeared

to authorize the use of 75 ft-lbs of

torque

was approved

by Engineering,

Operations,

and equality

Control.

Following performance of the work order,

the packing

leak was significantly reduced.

The failure of the

MNCR

analysis to specify appropriate

acceptance

criteria for the

maximum torque allowed appears

to be

a violation of NRC

requirements

(530/90-12-01).

On March 20,

1990, the inspector

observed

a portion of a

corrective maintenance

Work Order

(WO 00415554)

on Main Steam

Isolation Valve (MSIV)-180 in Unit 3 and noted that the

WO had

not been

signed

by the Shift Supervisor

(SS).

Thus the

signature certification for approval for the work and

verification of redundant train operability was not present

as

was required

by the licensee's

work planning and implementation

procedures.

When the inspector questioned this, the

maintenance

foreman

on the job immediately stopped all work and

returned to the Control

Room and obtained the

SS signature.

The inspector

determined that the

SS

had conducted

a pre-job

briefing with the maintenance

personnel,

had authorized

the

work to be done,

and

had verified redundant train operability.

Both the

SS

and the foreman accepted partial responsibility for

failing to ensure

the authorization signatures

were properly

affixed.

Licensee

management

counseled

the involved

individuals and communicated

a caution to all other foreman

and

Shift Supervisors.

The inspector

noted that although the

omission of the

SS signature

was

a violation of licensee

procedures

required

by Technical Specifications,

the safety

significance of the omission

was negligible and licensee's

corrective action was prompt.

Thus, the violation is not being

cited because

the criteria specified in Section

V.A. of the

Enforcement Policy of 10 CFR Part 2, Appendix C, were

satisfied.

Reactor Coolant

S stem

(RCS)

Leak Durin

Valve

Re ackin

- Unit I (62703)

On March 29,

1990,

mechanics

were repacking valve PSI-AV-458, which

crossties

the shutdown cooling system

and the fuel pool cooling

system, with the valve presumably

closed.

During the work the last

two rings of packing were forcibly ejected

from the valve by

shutdown cooling system pressure.

The mechanics

attempted

but were

unable to reinsert the packing while leakage

was approximately

11

30

gpm.

Pressurizer

level decreased

from 55 to 47 percent since

letdown and charging were secured at the time.

After calling the

control

room, radiological protection,

and their supervisor,

the

mechanics left the area

and were subsequently

found to not be

contaminated.

Several

supervisory individuals responded

to the

event

and reduced the leak rate to 15

gpm by removing the mechanical

stop

on the remote actuator

and shutting the valve more fully.

The

"B" Train shutdown cooling loop was then warmed

up and placed into

service in accordance

with the operating procedure.

The shift

supervisor

allowed the reduced

leak to continue while warming up the

"B'rain based

on the fact that pressurizer

level

was being

controlled with charging

and letdown returned service,

and the water

leaking from the valve was draining to floor drains without

significantly worsening the existing radiological conditions.

After approximately

1>> hours

the "B" shutdown cooling loop was

placed in service

and the "A'oop was isolated

and drained.

Since

the "B" shutdown cooling loop was available,

the decision to attempt

repacking valve SI-UV-458 with 150 psig system pressure

against it

appeared

to the

NRC inspector to represent

poor maintenance

planning.

The licensee

responded

by restricting the repacking of

valves which could not be isolated

and drained, to valves which are

only exposed to static

head pressure.

The licensee further committed to evaluate

and promulgate the

criteria for and authority required for repacking unisolated

valves

at pressures

above

a static

head.

The inspector

concluded that the

work schedulinq for this activity was poor in that it failed to

consider minimizing core cooling vulnerabilities, worker safety,

the

potential for spreading radiological contamination,

and redundant

train availability.

This event

was briefly discussed

in a meeting with APS and Region

V

management

personnel

on March 30, 1990, which followed an

enforcement

conference

of the

same

day related to radiation

protection concerns.

No violations of NRC requirements

or deviations

were identified.

Poor Freeze

Seal

Work Im lementation - Unit 1 (62703)

The inspector

reviewed the work package for placing

a freeze

seal

on

the piping between

the spray chemical addition tank and valve

SIA-UV-603 and observed

the freeze

seal while it was in progress.

Procedure

33MT-9ZZ02, "Freeze Sealing",

contains

Appendix E, Freeze

Seal

Safety Evaluation sheet,

which had been prepared

by the planner

on June

10,

1988.

The inspector

questioned

three aspects

of the

planning documented

in Appendix E.

Section l)C) of Appendix

E

identifies the

maximum pressure

expected

across

the freeze

seal

as

20 psig and Section 1)D) lists relief SI-PSV-250

as the upstream

relief.

On March 19,

1990, while the freeze

seal

was in place, this

valve was tested

and found to relieve at 30 psig rather than

15 psig

as intended.

The Spray Chemical Addition Tank was at atmospheric

12

pressure

at the time so SI-PSV-250

had

no actual

impact on the

freeze seal.

Section l)C) lists measures

to ensure

the

maximum differential

pressure

across

the freeze

seal

is not exceeded.

One of these

measures

listed is to "Monitor SI-PI-336 periodically."

SI-PI-336

is a remote reading pressure

transmitter

which is only indicated in

the Control

Room.

The inspector questioned

the Control

Room

operators

whether they were, or had been,

asked to monitor SI-PI-336

periodically during the freeze sealing operation

and they responded

that they were not specifically monitoring SI-PI-336 and

had

received

no requests

to do so.

Section 4)0) identifies radiological considerations

in the job

planning process.

The planner indicated "Non-Radioactive"

even

though the Spray Chemical Addition system connects directly to the

suction of the containment

spray

pumps which are part of the

shutdown cooling loop and connected to the refueling water tank,

both of which -are contaminated

systems

and sometimes

require hot

particle controls.

The inspector

determined that the spray chemical

addition tank is sampled for hydrazine but not activity.

However,

the inspector

noted that the sample

and container

are handled

as

potentially contaminated:

When the inspector

reviewed the package after the freeze

seal

was in

place,

the Mork Group Supervisor

(WGS) review signature

was noted to

not be present

on the

WCSE checklist.

When the inspector questioned

the

WGS, the

MGS reviewed

and signed the checklist and explained

that this checklist

was

no longer used

and that

he did not notice

the blank when

he reviewed

and signed the

WO.

The

MO did not contain contingency plans in the event the freeze

plugs were to thaw or otherwise fail to seal.

The inspector

acknowledged that the

MCSE checklist contains

some of the

information which would be included in contingency planning.

The

inspector

concluded that there

was not complete contingency planning

for this job.

The licensee

was planning

on revising 33MT-9ZZ02, "Freeze Sealing,"

when this job was being performed.

After the inspector questioned

these

various issues

with the

WGS, the

MGS and his Supervisor

met

with the inspector to discuss

a draft of the proposed

changes

to the

freeze sealing procedure.

Several of these

issues

were already

addressed

in the draft primarily by the addition of a Freeze

Seal

Coordinator

who will be responsible

for coordinating the diverse,

inter-department

responsibilities

among the various work groups.

The draft also included

an expansion of the

WCSE check list to

include detailed contingency plans for the failure of the seal

and

a

loss of ventilation in the freeze

seal

area.

The inspector

concluded that the planned

changes

appear to be improvements

which

address

these

concerns.

The inspector

had

no further questions.

No violations of NRC requirements

or deviations

were identified.

Containment

Pre-Closeout

Ins ection - Unit 1 (71707).

During licensee

preparation

for closeout of the Unit 1 containment,

the inspector

noted several

deficiencies

not previously identified

or included

on the "Containment Closeout

Punch List."

The

deficiencies

included improper valve locking devices,

an unconnected

grounding cable for a safety-related

conduit,

and several

examples

of deteriorated

"Seal-Tite" sheathing

on Anaconda flexible conduit

for safety-related

and non-safety-re1ateg

components

(none with

Environmental gua1ification),

several

burned-out lights,

and

apparent boric acid accumulation

on various piping.

The licensee

promptly addressed

the deficiencies

and repaired the conduit.

No violations of NRC requirements

or deviations

were identified.

Eatin

and'Smokin

Debris Inside The Radiolo ical Control Area

n1

On three separate

occassions,

the inspector

observed

indications of

possible eating or smoking on the Auxiliary Building roof,

a

radiological control area.

Smoking or eating in thss

area is

prohibited by the licensee's

procedures.

The licensee

issued

a

memo

to all plant radiation workers after the first observation

indicating that eating

and smoking materials

could

no longer be

brought into the

RCA.

Approximately two weeks later, the inspector

noticed additional debris

on the Auxiliary Building roof.

The

licensee

made

a more thorough inspection

and found more debris.

Two

days later, the inspector noticed another indication of eating

on

the Auxiliary Building roof.

A prior example of food debris

and

cigarettes

in the

RCA was reported in inspection report

50-530/88-39.

The licensee

responded that the

new policy required

time to be fully effective.

Mhile it was too soon to evaluate

the

effectiveness

of the

new policy, the licensee

committed to make more

frequent observations

for at lease

one month in the areas

where

evidence of eating

or smoking in the

RCA have

been

noted in the

past.

No violations of NRC requirements

or deviations

were identified.

On March 21,

1990, with Unit 1 in Mode 5 while preparing to repair

the cabinet slides

and

make other hardware

and circuit repairs to

the

Log Power

Excore Neutron Flux Instrumentation

and Plant

Protection

System

(PPS) cabinets

and drawers, all four channels

of

Log Power Excore Neutron Flux Instrumentation

were deenergized.

The

cabinet slide work was to be done by a vendor who had

a work policy

of not working on energized

equipment.

The Technical Specification

Limiting Condition for Operation

(LCO) 3.3-1 and associated

Table

3.3-1 require

two channels

of Log Power Instrumentation

in Mode

5

and specifies

actions with only one channel

operable.

The

NRC

inspector

concluded that a violation of TSLCO 3.3-1 occurred in that

TSLCO 3.3-1 required at lease

one channel

of log power available

when in Mode

5 and did not cover the situation of all Log Power

channels

inoperable.

After discussions

with the

NRC, the licensee

re-energized

two channels

of Log Power Instrumentation.

The

inspector further concluded that the safety significance of

down-powering the

Log Power

channels

was reduced

since both startup

~ channels

and associated

Boron Dilution Alarm Systems

were operable

at the time.

The inspector considered that the work planning

was

poor in that while the contractor would not work in energized

cabinets,

the

APS staff would not have

been prevented

from doing so.

This event

was briefly discussed

in a meeting with APS and Region

V

management

personnel

and on March 30,

1990 which followed an

enforcement

conference of the

same

day related to radiation

protection concerns.

This is an apparent violation of NRC requirements,

Enforcement

Item

(528/90-12-01).

Fires

on the Instrumentation

and Control

I8C) Sho

Roof

nl

On April 3, 1990,

and April 9, 1990,

two fires occurred

on the Unit

1 Instrumentation

and Control (I8C) shop roof as

a result of welding

slag which fell from construction activities adjacent to the roof.

An Operations

Support Building is being constructed

and tied to the

existing Control Building above the

I8C shop roof.

The fires were

localized

and declared

out by appropriate

individuals less

than

10

minutes after discovery.

No Notice of an Unusual

Event was

declared.

The onsite Fire Department did respond in both cases.

The inspector questioned

the licensee

and the contractor supervisor

for the construction activities regarding fire watches.

For the

first fire, a fire watch was not present

nor required since the

contract stated that fire watches

would only be required

when hot

work is occur ring on existing structures.

The Hot/Work Permit did

not require

a fire watch because it incorrectly stated that

no

flammable material

was within 35 feet of the hot work.

After the

first fire, the Manager of Nuclear Construction directed the

contractor to utilize fire watches for all future welding, cutting,

burning or grinding activities being performed over,

on, or in

existing structures

regardless

of whether weld/burn permits required

them or not.

A fire watch was present

during the welding activities which caused

the second fire.

The fire watch procedure

requires

a fire watch to

be posted during the

30 minutes after hot work activities

have

ceased.

During the welding activity on April 19, 1990, the Fire

Marshall issued

a Stop Work Order because

the fire extinguisher

available to the fire watch was marked

as not having

a current

inspection.

Approximately twenty-five minutes after the welding

ceased,

the fire watch asked

a roofer to watch the area for five

more minutes

so the fire watch could get

a properly marked/current

fire extinguisher to address

the Fire Marshall's

concern.

It was

during this five minute period the fire was discovered

as smoldering

felt wrapping.

A fire blanket

had been placed over the combustible

material,

but had been

removed during another activity without

objection from the fire watch.

The Plant Hanager

stopped the

construction activities until an incident investigation report was

complete

and satisfactory to the plant manager.

Corrective Actions

included retraining fire watches

in the Hot Work Permit procedure,

requiring currently marked fire extinguishers

and requiring fire

blankets.

No violations of NRC requirements

or deviations

were identified.

Snubber Visual Ins ections

Performed Without An Available

roce ure -

n>

During the

NRC inspector's

review of snubber

inspections

being

performed,. technicians

performing the inspections,

(procedure

73ST-9ZZ21),

were unable to identify or locate the work order or

procedure

by which they were working.

The technicians

had

an

unofficial checklist with them identifying the snubbers

to be

inspected

and the characteristics

to be inspected.

However, the

checklist- did not specify the inspection

method or acceptance

criteria.

The technician

searched

through documents

stored at the

hot tool issue counter

and in the snubber trailer, but still was

unable to locate either the procedure

or the work order.

The

technician did find some completed

data sheets

from the appropriate

procedure

from other snubber inspections,

from which the inspector

confirmed that the informal checklist correctly identified all

required. inspection points.

Later in the day, the technician

s

supervisor

produced the approved surveillance test procedure,

confirming that the work was authorized.

The inspector

concluded

that use of an informal check list appeared

to be inconsistent with

licensee policies,

however

no technical

concerns

were identified in

this case.

The licensee

acknowledged that workers not having ready

access

to work documents,

especially surveillance test procedures,

during the performance of work is inconsistent with licensee

policies.

No violations of NRC requirements

or deviations

were identified.

Zone III Controls - Unit 2 (93702

On approximately April 5, 1990, the licensee

discovered

approximately

44 small

beads,

later confirmed to be lead, inside the

cleanliness

Zone III controlled area

around the reactor cavity.

At

the time, the unit was defueled

and the cavity was drained.

The

beads

were found primarily along the rails adjacent to the cavity,

though

some were found in other areas,

including on the rails,

and

on the refueling machine.

An inspection of the edges of the cavity

was performed but no beads

were identified within the cavity or in

the reactor coolant system.

The licensee

performed

an engineering

evaluation of the beads

(EER 90-ZC-051)

and determined that

a small

number of lead beads

which are

used for shielding or weighing down

purposes

would not present

a safety concern

and would not interfere

with reactor operations

or water chemistry.

The licensee's

16

investigation of this event is still in progress

and will be

evaluated

by the inspector.

The inspector

toured the Zone III controlled area

and found another

bead,

some pieces of degraded rail,

some lock wire and other small

debris along the rails.

Additionally, the inspector

found that -the

Zone III controls in place at this time did not address

work over

the reactor cavity and transfer canal.

Carpenters

and other

craftsmen

were working on grating over the transfer canal without

Zone III controls.

The grating was not covered with herculite in

all areas until after a screw dropped into the transfer

canal

and

a

nail fell onto the Zone III Attendant's

desk.

The licensee

subsequently

covered the grating and the end of the transfer canal

with herculite

and

gC suspended

the carpenters'ork

until

conditions were reviewed.

In this case,

a licensee

equality Control

Inspector

had noted the Zone III control problem and was attempting

to pick up loose material

on the grating when the screw dropped into

the transfer

canal.

The failure to adequately establish

Zone III

requirements

is a violation of 30AC-9MPOl, "Foreign Material

Exclusion and Zone III Controls," which appears

to be

a violation of

NRC requirements.

The violation is not being cited because

the

criteria specified in Section

IJ'.G. of the Enforcement Policy were

satisfied.

Plant Housekee

in

- Units j, and

3 (71707)

During the inspecti.on period the inspectors

reviewed the material

condition of plant equipment

and general

housekeeping

related to the

prevention of accumulation of combustible materials.

while Unit j.

has

been in an extended

outage,

equipment material condition was

reviewed in connection with the approach to restart of Unit l.

During the inspection period the inspectors

had the following

concerns

about storage of combustible materials

and plant

housekeeping.

In Unit 3 on March 5, 1990, while the Unit was at

full power operations,

the inspectors

observed

several

wooden

pallets,

2 wooden packing cases

about 2'x2'x3',

one apparently full

55 gallon drum of a chemical with a flammability tag of No.

3

(severe

hazard)

and several

other drums also labelled flammability

No.

These materials

were stacked

next to the Unit 3 Condensate

Storage

Tank (CST),

a safety-related

tank.

Licensee

procedure

14AC-OFP03,

paragraph

3.2. 10 states

that combustible material shall

not be stored next to outdoor safety-related

water storage

tanks.

This is an apparent violation of NRC requirements.

(Enforcement

Item 50-530/90-12-02).

In Unit 1 at the 140 foot eleVation of the Main Steam Support

Structure

(MSSS) areai

the inspectors

observed six cardboard

boxes,

approximately

2 x2'x3

apparently filled with'nsulating materials

on the "A" Train side

and similar boxes

on the "B" Train side.

Licensee

procedure

14AC-OFP03,

"Control of Combustible/Flammable

Materials

have

a storage

permit and

that

a copy be posted.

There

was

no permit posted

or issued for the

I

II

materials

stored

on the 140 foot elevation of the

MSSS area.

The

inspector

noted that none of the safety-related

equipment

was

required to be operable for the existing plant mode;

however,

licensee

management

agreed that it was not appropriate

housekeeping

to store

such material in that location and had it promptly removed.

Other Unit 1 poor housekeeping

conditions were noted by the

inspectors

on March

5 and 7,

1990 in the

77 foot and 87 foot West

and East mechanical

piping penetration

areas.

Three full and

over-flowing bags of contaminated

Radiation Protection

(RP) clothing

were noted,

various small

RP items were lying on, the floor both

inside

and outside of the posted

contaminated

zones,

and various,

tools, piping caps

and plant components

were left unattended,

loose

and not in use.

The inspectors

noted

a crescent

wrench which was

laying across

a contaminated

area

boundary.

In addition, the

inspectors

also noted

a number of valves with boric acid leaks.

These

included CHV-198, CHV-930, CHV-087, SIA-HY-691, SJA-UV-637,

SIB-UV-646 and CHB-HV-255.

Other observations

in this area

included

a number of emergency lighting boxes apparently with corrosion

products,

and

a section of metal flashing between buildings that was

severely corroded.

In the Unit 1 condensate

transfer

pump

room on March 7, 1990, the

inspectors

observed

several

plant equipment discrepancies:

(1)

CTB

V-031,

a test connection,

was

uncapped

and leaking; (2) under the

"B" condensate

transfer

pump, the drip pump drains were clogged

and

the pan

had approximately 1/2 inch of standing water and in the

water of the pan contained biological growth and corrosion products;

and (3) under the "A" condensate

transfer

pump was corrosion

and

standing water.

The condensate

transfer

pumps are listed in the

licensee's

FSAR as being required for safe

shutdown in the event of

a plant fire.

During the inspection the inspectors

expressed

concern to licensee

management

about these

housekeeping

and materiaI condition

observations,

particularly related to needed

improvements prior to

the restart of Unit 1.

Subsequently,

the inspector

observed

improvements

in the specific areas

noted

and otherwise in general

as

outage

work was completed.

One violation of NRC requirements

was -identified.

Stuck Shut Essential

Ventilation Exhaust

Dam er for "D" Batter

On April 4, 1990, the "D" Battery Essential

Exhaust

Fan

Damper

was

observed

by the inspector to be apparently stuck in the closed

position.

The inspector

had observed that the lever on the normal

exhaust

fan dampers

in all four Unit 3 battery

rooms

was

perpendicular to the flowpaths,

even though the normal exhaust

fans

were running.

By standard

convention this would indicate the

dampers

were shut.

Plant personn'el

could not readily confirm that

the dampers

were open

and therefore

the ventilation lineup was

altered to observe

the action of both the normal

and essential

18

exhaust

fans

and dampers.

The normal

dampers

were confirmed to have

been

open, with some air flow.

The "D" essential

damper

was found

to be stuck in the closed position when the "D" essential

exhaust

fan was started.

The damper technical

manual

states

that the damper

arm is to be positioned

as

needed to act as

a counter balance for

the damper.

= The arm may be installed in any position relative to

the actual

damper position to achieve this purpose.

Previously the

Unit 2 "8" essential

exhaust

fan damper

was observed

also to be

stuck

(See Inspection

Report 89-43).

The licensee

committed to

evaluating the preventive

maintenance

program in this area.

The "D"

essential

damper

was

r epai red and declared

operable

on April 6,

1990.

No violations of NRC requirements

or deviations

were identified.

on Unit 3 since the March 3, 1989, plant trip.

Procedure

73ST-3RC01,

"Reactor Coolant System Transient

and

Operational

Cycles," is intended to be performed monthly in order to

assure

that the requirements

of Technical Specification (T/S) 5.7

are satisfied.

The T/S does not specify

how often the analyses

to

demonstrate

compliance with T/S 5.7 is to be performed.

The licensee

did not perform the surveillance

because

the requisite

data

was not recorded

when the auxiliary spray system

was

used in

March 1989,

so

an engineering evaluation

had to be performed to

determine

the correct data to use.

The engineering evaluation,

EER

89-RC-245,

determined

the needed

data but also stated that the'/S

prescribed

formula for calculating auxi 1iary spray differential

temperature

should not be used.

This disposition clouded the issue

and resulted in an additional delay.

The licensee

has since

determined that this aspect of the disposition of EER 89-RC-245

was

inappropriate

and committed to perform the surveillance in

accordance

with the T/S methodology.

Since T/S Table 5.7-2 does not

extend to the range of differential temperatures

observed

during the

March, 1989, Unit 3 event,

and also in a Unit 1 event in 1986, the

licensee

performed

an evaluation

(EER 86-RC-159) to determine

an

appropriate

usage factor for the temperatures

observed.

The

surveillance

procedure,

73ST-3RC01,

includes this information.

The

NRC inspector

concluded that the licensee

had not exceeded

the

auxiliary spray pressurizer

nozzle cumulative

usage factor.

The

licensee

committed to reevaluate

a change to the T/S to include this

information.

No violations of NRC requirements

or deviations

were identified.

The inspector

reviewed the licensee's

documentation

related to the

condition in which AFM flow isolation valves

(AF-034 through 037)

l

19

were found not to go fully closed using the motor operator acting

against

design differential pressure.

This condition was

documented

in EER 87-AF-42 on the basis of actual test results in which the

valve remained

10 percent

open when it torqued out in the closing

direction.

The inspector

posed

several

questions with respect to

the associated

Justification for Continued Operation

(JCO).

These

questions

were not an immediate operability issue in that the

AFW

control valves wil1 provide

some pressure

reduction

so that the

AFW

isolation valves would not be required to close against full design

basis

event pressure

and flow.

In addition, the licensee's

response

to IE Bulletin (IEB) 85-03,

"Motor Operated

appeared

to document that

these

valves would fully close

The licensee

may need to be clarified and

commited to review their IEB 85-03 response.

These

questions

SG level

was stabilized at

approximately

84 percent.

,Operators

maintained auxiliary feedwater

flow to the

SG after securing

main feedwater.

The licensee

determined

the cause of the trip to be

a defective

circuit board in the

CEA No.

80 control cabinet.

The circuit board

was replaced

and retested satisfactorily.

The licensee

determined

that the component failure was

random.

The licensee further

determined that the initial unexpected

response

of one main

feedwater

downcomer control valve could be explained

by the

"sticking" of a transfer switch relay in the Reactor Trip Override

(RTO) portion of the Feedwater

Control

System

(FWCS).

Although they

were unable to duplicate this "sticking", Combustion Engineering

concurred with their conclusion

and the relay was replaced.

Finally, the licensee attributed the moderate

overfeeding of No.

j.

SG to leakage

by the economizer flow control valves.

They

determined that the I/P converter

had drifted slightly out of

calibration causing the valve to seat slightly (1/4 inch) above the

shut seat with a zero

demand signal.

These controls were

re-calibrated

and returned to service.

and several
