Summary of Plant Status

The unit began the inspection period with the output breakers closed and

the unit at 100 % power. The following evolutions occurred this

inspection period:

- On August 14. 1996 at 7:28 3.m.. reactor power was reduced to 94 %

due to flashing occurring in t1e hotwell following the closing of HDV-

61. HDV-61 is the drain valve from FWHE-3A to FWHE-2A.

!

- On_ August 17, 1996 at 7:37 a.m.

reactor power increase commenced

following the repair of HDV-61.

Reactor power was returned to 100 % at

7:00 p.m.

- On August 20, 1996 at 10:00 p.m.

reactor )ower was reduced to

approximately 60 % due to the loss of the B C)P.

See paragraph 02.1 for

more details.

- On August 22, 1996 at 1:18 a.m., a reactor power increase was

initiated after repairs to the B CDP.

Reactor power reached 100 % at

11:00 a.m. on August 22, 1996.

- On August 26, 1996 at 1:11 a.m. while at 100 %. a aower reduction was

commenced to remove CWP-1A from service to support scleduled

maintenance.

Reactor power of 85 % was reached at 3:35 a.m.

.On August 30. 1996 at 9:36 a.m. while at 85 % reactor power, a

Jower

-

reduction was initiated due to fan belt breakage on the generator

aus

duct cooling fan.

Reactor power was stabilized at 40 % at 2:04 p.m.

- Following repairs to both CWP-1A and the generator bus duct cooling

fan, reactor power was returned to 100 % at 9:55 a.m. on September 1.

1996.

'

- At 1:40 p.m. on September 2. 1996, a power reduction from 100 % power

was initiated due to low turbine lube oil pressure. The main generator

output breakers were opened at 9:00 p.m. on September 2. 1996, with

reactor power maintained at approximately 8 % of rated power.

- At 5:00 p.m. on September 3. 1996 the decision was made to place the

plant in Mode 3.

At 6:00 p.m. the plant entered Mode 2 (less than or

'

equal to 5 % reactor power).

At 6:20 p.m. the )lant entered Mode 3

(shutdown with reactor coolant system greater tlan or equal to 280

degrees F).

- Due to a problem identified with the turbine lube oil piping, the

decision was made to continue cooldown of the plant.

The plant entered

Mode 4 (280 degrees F > Tavg > 200 degrees F) at 9:05 p.m. on September

4. 1996 and established Decay Heat Operation at 4:30 a.m. on September

,

5. 1996. - Mode 5 (Tavg less than or equal to 200 degrees F) was entered

at 11:38 p.m. on September 5, 1996.

Conduct of Operations

01.1 General Comments (71707)

01.2 Plant Shutdown

During the plant shutdown on September 2, 1996, at 10:00 p.m., while at

a reactor power of ap]roximately 22%, secondary cycle samaling pump SSP-

4D tripped, allowing Jack flow from the sample valve to t1e condenser.

This resulted in substaritial air leakage into the condenser and an

increase in hotwell oxygen.

Chemistry personnel became aware that air

was being drawn into the condenser through the sample valve and closed

SSV-25.

PR 96-351 was written to document this problem and recommended

an evaluation be performed to add an in-line check valve that would

prevent similar events.

During the loss of vacuum in the condenser as noted above, operators

manually started a second vacuum pump -started a second gland water

pump, and increased the rate of power decrease.

This rapid power

reduction resulted in a pressurizer out surge and RCS pressure reduction

to approximately 2048 psig.

TS 3.4.1, RCS Pressure. Taperature, and Flow Departure From Nucleate

Boiling (DNB) Limits, Condition A, requires with one or more RCS DNB

parameters not within limits, restore the parameters to within limit

within two hours.

SR 3.4.1.1 requires loop pressure be equal to or

greater than 2061.6 psig with four RCPs operating.

During the evolution

noted above, the RCS pressure was below 2061.6 psig for approximately

two minutes, resulting in no violation of TS.

The licensee issued PR 96-354. RCS Pressure Less Than DNB Limit, to

address this issue on September 3, 1996.

The root cause analysis

determined one of the primary causes was that management expectations

concerning maintenance of primary plant parameters during events such as

this, were not clearly understood.

6

The licensee has developed a corrective action plan to address this

cause.

Interpretations of TS requirements during plant transients are

being developed.

An OSB entry is being developed detailing the results

I

of the event investigation and management expectations concerning

maintenance of primary parameters during plant transients.

The licensee

is revising the licensed operator training to address these management

expectations. The developed corrective actions for this event are being

tracked by the licensee and no further actions by the NRC are required.

Operational Status of Facilities a .iquipment

02.1 Loss of the B Condensate Pumo (717)

On August 20, 1996 at 10:00 p.m. with the plant at 100 % rated power,

the control room received a Condensate Pump B Uncoupled alarm followed

by a B Hotwell Level High annunciator alarm.

Operators verified the B

CDP was uncoupled and entered AP-510. Rapid Power Reduction, and reduced

reactor power to ap3roximately 60 %.

During the power reduction, the B

CDP was placed on t1e spare controller and demand was increased with no

response.

Investigation showed that the control cabinet for the B CDP

had no power and therefore the electromagnetic coupling was not

functioning.

The condensate pumps are located on the 95 foot elevation

of the Turbine Building on the northeast and northwest corners of the

main condenser.

Each pump assembly is set into a deep pit enclosure

located below the 95* elevation.

The' pump and motor shafts are not mechanically connected.

They are

coupled via an electromagnetic coupling device, which allows the speed

of the aump to be varied while the motor turns at a constant speed of

1150 RPi. As the output of the pump controller is increased, an

increasing voltage is applied to the electromagnetic coils.

This causes

an increase in the magnetic field strength between the motor and pump

shaft, causing the pump shaft to begin to follow the motor rotation.

There are three condensate pump coupling control cabinets located on the

i

95 foot elevation of the Turbine Building on the north end of the

condensers.

The two outside cabinets are designated as the normal

controls for its respective condensate pump.

The center cabinet is a

spare coupling controller and may be selected for use on either

condensate pump. A select switch, mounted on the spare controller

l

cabinet, is used to select A or B condensate pump to the spare

controller.

Technicians replaced blown fuses in the B aump and spare control

cabinets.

The available evidence for the alown fuses was inconclusive,

with the most probable cause being a ground on the brushes or slip rings

caused by build up of carbon dust from the brushes. The pum) was tagged

out, the brushes replaced and the slip ring area cleaned.

T1e B CDP was

run with no load and the pump was swapped to the spare controller and

back to normal to verify that both controllers were functional.

PR 96-

327. Loss of CDP-1B coupling causes power reduction from 100 % to 62 %.

was written to document this problem.

A reactor power increase commenced at 1:18 a.m. on August 22, 1996.

02.2 Circulatina Water Pumo 1A Reoairs (71707)

On August 26. 1996 at 1:11 a.m. while at 100 % reactor power, a power

reduction was initiated to remove CWP-1A from service for scheduled

maintenance.

Reactor power was stabilized at 85 % at 3:35 a.m.

Following completion of the 10 R refueling outage, the licensee observed

degradation in the discharge )iping of the circulating water pumps. An

interim maintenance plan has Jeen implemented to periodically remove one

of the CWPs from service'and provide a temporary repair utilizing

Belzona.

N.3 Generator Bus Duct Coolina Fan (71707)

A' drive belt on generator bus duct cooling fan TBF-1 was evaluated and

found to need replacement.

If the generator bus duct cooler is lost,

power must be reduced so that the generator current-is below 10,000

amps. A power reduction was initiated at 9:36 a.m. on August 30, 1996,

and reactor poner was stabilized at 40 % (313 MWe), with generator

current at 8.770 amps at 2:04 p.m. on August 30, 1996.

After replacement of the belts, the generator bus duct cooler fan was

placed back in service at 8:00 a.m. on August 31, 1996. After a run-in

period and tension test for the new belts, a power increase was

initiated at 3:00 p.m. on August 31, 1996.

Since CWP-1A had been

returned to service also (see paragraph 02.2), reactor power was

returned to 100 % at 9:55 a.m. on September 1, 1996.

02.4 Decreased Turbine Lube Oil Pressure (71707)

At 4:00 p.m. on August 30, 1996. Crystal River 3 received an auto-start

of the main turbine ac Jowered back-up bearing oil pump (TBP-2) and the

j

high pressure seal oil Jack-up pum) (TBP-8) on low lube oil pressure.

' eis auto-start of the ac powered Jack-up oil pump occurs at 10-12 psig.

At the time, the unit was at approximately 40% power, in the process of

reducing power to replace one failed and one degraded fan belt on the

main generator bus duct cooling fan (see paragraph 02.3).

TBP-8 was

!

returned to standby, but TBP-2 restarted when a shutdown was attempted,

j

Main lube oil pressure remained at approximately 18 psig with TBP-2

operating.

This is the normal operating lube oil pressure.

The main turbine lube oil system consists of the main oil pump (TBP-1),

l

the AC turbine bearing oil pump (TBP-2), the DC turbine bearing oil pump

l

(TBP-3), the high pressure seal oil backup pump (TBP-8), the bearing

lift oil pump (TBP-6), the lube oil ejector and the main turbine lube

oil reservoir (LOT-2), with its associated heaters, coolers, and va)or

i

extractor.

Under normal full power operating conditions oil from t1e

i

main turbine lube oil reservoir is routed to the individual bearings on

the main turbine by the lube oil injector.

The main oil Jump, which is

attached to the shaft of the main turbine, )rovides a hig1 pressure

supply of oil that is used to operate the tirust bearing trip device and

serves as a backup source of oil to the seal oil system.

The main oil

pump and lube oil ejector are dependent on each other. The main oil

!

pump depends on the lube oil ejector for its suction supply and the

ejector uses the discharge of the main oil pump as its motive force.

The ac powered turbine bearing oil pu p (TBP-2) is located on and takes

I

suction from the main turbine lube 01

reservoir.

TBP-2 is interlocked

'

to auto start any time bearing lube oil pressure drops to below 10-12

psig. TBP-3 is interlocked to autostart any time bearing lube oil

i

pressure drops to below 8-10 psig as sensed by TB-253-PS.

After discussions with Westinghouse, the licensee issued STI 96-029 with

guidance for operations. This guidance included the following:

- Maintain lube oil temperatures as low in the normal band as possible.

i

To facilitate this, both SCPs were placed in service,

-

If turbine lube oil pressure degrades below 14 psig while TBP-2 is in

o]eration, the turbine should be removed from service via a controlled

slutdown.

j

-

Increase the frequency of monitoring lube oil pressure.

After a review of the data, engineering recommended that the plant

continue to run TBP-2 continuously and return the plant to full power

following repair of the bus duct cooling fan.

The plans were to

schedule an outage to repair the low lube oil pressure problem. At 9:55

a.m., on September 1, 1996, the plant was returned to full power

operation.

At 6:30 p.m., it was noted that turbine lube oil pressure had continued

to degrade, at a rate of 0.8 psi / day. At 9:00 a.m. on September 2,

1996, a meeting was held to discuss the troubleshooting plan for the low

lube oil pressure concerns. At 1:40 p.m. on Seatember 2, 1996, the

decision was made to decrease power and place t1e turbine on turning

gear, in order to troubleshoot and make repairs.

The main generator

output breakers were opened at 9:00 p.m. on September 2, 1996 and

reactor power was maintained at approximately 8% of rated power.

At 4:55 a.m. on September 3, 1996, when the maintenance technicians

began removing the hand hole cover over LOV-471, oil came out.

The

.

licensee removed the adjacent manway cover and saw oil spraying inside

the tank from the area of check valve LOV-471.

Upon further

investigation, it appears that the line downstream of LOV-471 has a long

longitudinal split. The licensee )roceeded to go on decay heat and

stayed in Mode 5.

At the end of tais inspection period, the lube oil

tank was drained in order to make repairs.

Hiscellaneous Operations Issues

08.1 Emoloyee Concerns Proaram

-

a.

Insoection Stone (40001. 40500)

An inspection was conducted to evaluate the effectiveness of the

licensee's Employee Concerns Program. The inspection included a program

review, employee interviews, and documentation reviews.

.

-

6

The inspectors reviewed the licensee's program as cutlined in Nuclear

Operations Department procedure N00-36, Employee Concerns Program,

Revision 6 and. interviewed the Employee Concerns Representative who

administers the program. The interview with the Employee Concerns

Representative focused on his qualifications for the position, as well

as a review of the program and data related to the concern

receipt / closure rate, number and age of open concerns, and outage time

frames.

The inspectors interviewed 28 employees from various levels (i.e.

managers and technicians) and disciplines, including:

engineering,

operations, maintenance, chemistry, health physics, security and

training personnel. The selection was random, except the selection was

made by departments in order to obtain a representative sample from the

various work disciplines. This interview sample size was consistent

with other inspections of this nature.

Personnel interviewed were asked

if they would report safety concerns to their su

whether they were knowledgeable of the licensee'pervisor or management. j

s concerns program and

how to use the program, whether the licensee's facilities were

adequately accessible, and whether they felt uncomfortable or knew

someone that had been badgered for reporting safety concerns.

Personnel

who stated they had used or had knowledge of someone who had used the

concern program were asked about timeliness and adequacy of concern

l

resolution.

Eleven closed employee concern files from the 1995/1996 time frame were

reviewed to determine the adequacy of the licensee's investigation and

corrective actions.

Files selected included both substantiated and

i

unsubstantiated concerns. Specifically the inspectors reviewed the

files to determine if overviews and summaries of activities related to

.

the concerns (i.e. , priorit , investigations, and communications) were

i

adequate to address the emp oyees' safety concerns.

Additionally the

inspectors evaluated each f le to determine if concerns were clearly

,

l

identified, and if closeout letters to the concerned employee adequately

described the concern, the extent of the licensee's review, whether the

'

employee's concern was substantiated or not substantiated, and any

planned corrective actions.

!

The inspectors also conducted a review of the anonymous precursor cards

j

(e.g. low level corrective action documents written by persons unknown)

which had been written in the last six months at the site.

A listing of

"

these cards, which included a description of the problem and the

corrective action taken, was provided by the licensee and reviewed by

',

the inspectors.

In addition, data concerning the number of anonymous

'

precursor cards written versus the total number of precursor cards

written during 1994 through August of 1996 was provided and reviewed.

!-

l

.b.

Observations and Findinas

The Employee Concerns Program is small and relatively informal, staffed

i

with only one individual.

The number of concerns received in the

program is also small, and the safety significance of those concerns is

i

$

,

.,,

,,

,

limited. The number of concerns received was as follows: 1993 - 8

concerns from exit interviews and 34 from working employees (42 total):

1994 --74 concerns from exit interviews and 35 from working employees

(109 total): 1995 - 8 concerns from exit interviews and 6 from working.

employees (14 total): 1996 - 40 concerns from exit interviews and 10

from working employees (50 total). The high number of concerns in 1994

'

was attributed to some company downsizing and a refueling outage. The

low number of concerns in 1995 was attributed to management development

'

and support of the Precursor Card Program. The high number of concerns

in 1996 was attributed to a refueling outage.

Also, timeliness of

concern resolution was adequate, with only 1 concern open from 1994 and

12 open from 1996.

During the inspection,' the number of anonymous precursor cards raised

some concern on the part of the inspectors.

Further investigation of-

this area resulted in resolution of this concern as follows:

Review of

the anonymous precursor cards written in the last six months determined

that there were a total of 110 written.

Review of a listing of these

cards, however, revealed that only five of these cards had any safety

1

significance, and the NRC had already investigated the problems

1

identified on two of those five cards. Additionally, further comparison

of the number of anonymous cards to the total number of cards written

j

determined that the percentage of anonymous cards was very small,

averaging less than four percent (1994 - 45 of 719, 1995 - 83 of 2886,

and 1996 - 117 of 3959).

Proaram Strenaths:

All employees interviewed stated they had confidence in the ability of

their management to safely operate the plant.

Essentially all personnel interviewed expressed confidence in management

and a receptiveness on the part of management regarding identification

of safety concerns.

!

All personnel interviewed stated that they would raise safety issues

L

through their management, the corrective action program, the Employee

l

Concerns Program or the NRC.

All personnel interviewed stated that they would resolve safety issues

through their line management and the licensee's corrective action

program prior to involving the Employee Concerns Program or the NRC.

{

Most personnel were familiar with the existence of the licensee's

!

concerns program and felt that accessibility to the program was

j

acceptable. Only a small percentage of the people interviewed had used

the program.

The site employee concern representative provided adequate physical

3rotection of the files, and all records related to investigations were

!-

cept in locked storage with restricted access to protect the

individuals' identities.

In most cases reviewed, the closecut letter to the concerned employee

was completed.within four months from receipt of the concern, The

inspectors' review of the files indicated that the quality and

timeliness of the licensee's reviews of concerns, investigations, and

followup with concerned employees was adequate.

Procram Weaknesses:

The percentage of concerns in the security area was unusually high. The

licensee provided information which indicated recognition of this

problem, including a self assessment of the security area.

Resolution

of many of the issues identified in the assessment was not completed,

however, and continued management attention to this area is warranted.

The inspectors were informed that SBI Security has a separate concerns

program, which is managed from SBI's corporate office.

SBI is the only

contractor which has a significant number of personnel on site.

Although SBI personnel frequently use the licensee's program, SBI's

corporate program is available for use by SBI personnel working at

Crystal River and is not audited by the licensee.

When requested by the

inspectors, the licensee stated that they were not knowledgeable of the

extent of use, if any, of the SBI corporate program by site SBI

personnel.

Concerns are closed out based on actions which will be taken in the

future to resolve a concern without any followup to verify completion of

those corrective actions (i.e., corrective action recommendations are

not tracked through implementation),

The Employee Concerns Program relies on the corrective action program

for resolution of some concerns, and yet the Employee Concerns Program

and the corrective action program are not tied together. Although

technical reviews of the concerns were effectively performed such that

concerns were fully investigated, closure packages did not always

include documentation to demonstrate that the employee's concern had

'

been adequately addressed.

However. when requested by the inspectors

the Employee Concerns Representative was able to produce documentation

such as precursor cards to show that selected deficiencies had been

documented.

,

Some of the individuals who had used the Employee Concerns Program were

not satisfied with the results.

Some of this can be attributed to a

lack of followup with the concerned individual to assure they fully

understood all corrective actions taken.

Others were not satisfied with

the timeliness of concern resolution.

This perception, whether factual

or not, has a tendency to su) press the effectiveness of an employee

concerns program _and should 3e addressed by the licensee.

Although letters to concerned individuals do address whether or not any

corrective actions will be taken, the employee concerns packages and

letters to the individuals do not reflect whether or not the concern is

>

substantiated or not substantiated,

.

Nuclear Operations Department procedure NOD-36 requires the concerned

individual be notified if a concern resolution will take longer than

-

30 days. There is no documentation included in the concern packages

which reflects this action.

The letter to the concerned individual in one file did not accurately

reflect the actual corrective action, which had resulted from the

'

licensee's review of the concern. Corrective actions described in the

letter would not have been adequate to fully resolve the concern.

However, the inspectors noted that actual corrective actions completed

,

by the licensee were adequate. The inspectors were informed that the

-

concerned individual would be notified that additional corrective

'

actions had occurred.

.

c.

Conclusions

.

The inspectors concluded that the licensee's program was effective in

handling and resolving employee safety concerns.

Employees who were

interviewed knew about the licensee's concerns program and would use it

j

if they needed to, but most were generally satisfied with their

'

,

supervisors' rece]tiveness to resolving safety concerns without the

intervention of t1e concerns arogram. Accessibility to the program was

thought to be acceptable to t1e people interviewed. The inspection

determined that the technical issues in the )rogram were being

,

adequately resolved. The inspectors noted t1e willingness of licensee

4

employees and management to identify and resolve safety issues through

the normal chain of command and site corrective action programs.

The

inspectors concluded that, even though the Employee Concerns Program is

e

a small and informal program it is adequate.

Mode (62707)

On August 13. 1996, during performance of PT-366. Toxic Gas Detection

System Calibration, an iriadvertent actuation of the toxic gas system

'

occurred. While performing step 4.7.1. the contract technician was

instructed to ) lace the SAMPLE /ZERO switch to the ZERO Josition.

By

error, the tecinician placed the main power switch to tie OFF position.

This caused the monitor to deenergize and tripped the control complex

.

ventilation system to the emergency mode. The technician, realizing

that something was wrong, placed the power switch back to the ON

'

position.

In response, the operations SSOD had the technicians stop the SP, and

required the I&C supervisor to directly supervise restoration of the

i

system to its normai alignment.

A precursor card was initiated and

,

plant management was notified.

The licensee initiated a HPES evaluation

to determine probable root causes.

On August 15. 1996 a MRP meeting was

.

held to discuss the issue, determine adequacy of the evaluation, and

begin the development of a corrective action plan.

The HPES evaluation identifiea several causes for the inappro)riate

actions, including: (1) not having the su) plied 3rocedure in land while

4

performing the actions, (2) not using STAR, (3)

laving a non TPM

qualified technician independently performing procedure steps, and (4)

failure to maintain constant communications while performing the task.

A number of contributing factors were also diccussed, including: (1)

management did not provide adequate training to temporary personnel on

the use of procedures

(2) management has not constantly reenforced the

Event-Free operations program to plant personnel, (3) effective

monitoring of the use of procedures is inadequate, (4) management has

not provided adequate training on STAR to temporary personnel , (5)

management has not conveyed adequately to all maintenance personnel the

need to eliminate all inadvertent actuations of equipment in the plant,

and (6) job assignment did not take into account the need for two TPM

qualified technicians to perform the independent tasks of PT-366.

The inspectors attended the MRP meeting where the results of the HPES

were discussed.

The DNPO constantly challenged the assessors to defend

their conclusions and to provide him with corrective actions that would

address the contributing factors, as well as the identified primary

4

'

causes, One comment made by the HPES evaluator was that there is

evidence of a perception at CR3 that adherence to procedures and STAR is

pro)ortional to the consequences of not using them.

The DNP0 agreed

wit 1 the statement, and directed the responsible personnel to determine

the root cause of this perception and develop corrective actions to

address it.

The MRP conducted for this event was very detailed and

stressed identifying all of the contributors to this problem.

Technical Specifications (TS) 5.6.1.1 requires written procedures be

established, implemented, and maintained covering the applicable

3rocedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A,

r bruary 1978.

RG 1.33, Appendix A requires administrative procedures

e

regarding prncedure adherence. AI-400E, Performance and Transmittal of

Procedures, paragraph 1.1, Policy, states that verbatim compliance of

procedures is required, but procedures must not be blindly f6110wed.

The technician's failure to follow the requirements of PT-366 is a

violation, VIO 50-302/96-09-01, Failure to follow a procedure resulting

in the inadvertent initiation of the control room emergency ventilation

Maintenance Procedures and Documentation

M3.1 Surveillance Observations (61726)

The inspectors witnessed portions of the performance of PT-325, Turbine

Generator Checks.

During the surveillance, the C MSR combined

intercept /stop valve failed to stroke.

Following maintenance

troubleshooting of the controller, the valve was stroked successfully.

The cause of the valve failing to stroke was not determined. The

following day, while performing the procedure for the remaining MSRs,

the A valve stroked, as required, but the B and D valves failed to

stroke.

The licensee again performed troubleshooting, but no

discernible problems were identified.

After reviewing industry experience and discussing the situation with

.

the turbine vendor, the licensee determined that the most 3robable cause

of the problem was excessive moisture in the EHC fluid.

T1e moisture

would interfere with the operation of the control solenoid. As interim

corrective actions. the licensee replaced the Fuller earth filters on

the oil and filled the EHC oil tank, to decrease available volume for

moisture containing air to occu)y. The inspectors verified that the

interim corrective actions had Jeen completed. The licensee is

continuing to work on a permanent solution to address this concern.

Appendix B. Criterion III, discussed at a predecisional enforcement

1

conference on March 27, 1996. This issue involved failure to revise

Operations Procedures, or to provide training to operators, after

modifying Valve MUV-64 to change the Valve Operator from a disabled air

operated valve (locked in the open position) to manual operation with a

handwheel, in accordance with MAR 95-01-07-01.

The MAR was implemented to address, in part, the concerns of operations

personnel regarding the loss of level indication in the Makeup Tank

(MUT) during Loss of Coolant Accident (LOCA) conditions, and the

)otential for hydrogen gas being entrained in the suction to the Makeup

Jumps (MVPs).

The design input record of the MAR package discussed

adding the manual gear driven chain operator for better access in the

manual mode, since it might be necessary to quickly stroke the valve

closed in certain accident scenarios with the new higher MUT hydrogen

gas pressures (e.g. , certain Appendix R fires, keeping the MUT level

indication on scale post LOCA rapid boration requirements, etc.). The

valve was identified in the valve lineup section of operating procedure

OP-402. Makeup and Purification System. Revision 84.

The procedure only

showed the valve position as being sealed open, and there was no

discussion on operation of the valve during potential accident

conditions.

b.

Observations and Findinas

Upon further review, the NRC determined this issue is substantially

different and not an additional example of the apparent violation,

Conclusions

This issue is identified as VIO 50-302/96-09-05. Failure to Incorporate

determined that no procedures needed to be revised.

During the current

inspection, the licensee continued to disagree with the NRC position

since, based on calculations in process in parallel with implementation

of the MAR, they did not plan to operate valve MUV-64 during accident

conditions. After further discussion. in order to add conservatism

during accident conditions, the licensee decided to revise Emergency

Operating Procedures (EOPs) 7 and 8 to: (1) reverse the High Pressure

Injection (HPI) " piggyback" transfer prior to swapping the Building

Spray and Decay Heat Jumps to the Reactor Building (RB) sump, resulting

in isolation of the MJP from the_MUT earlier in the transfer sequence,

and-increasing the available NPSH for the HPI pumps, and (2) closing

,

MUV-64 if accessible.

In addition. a revision to the OPS Study Book

Paragraph R1.1 of NRC Inspection Report 50-302/96-04 noted that the

licensee has identified other examples where implementing procedures do

not agree with the FSAR. These exam)1es were identified as part of the

licensee's ongoing FSAR Operational Review Project, which is a detailed

review comparing the FSAR with the Design Basis Documents and other

plant documents to ensure consistency and compliance with the FSAR.

Although a significant number of discrepancies have been identified,

none have been determined to represent loss of safety function or to be

outside the design basis of the plant. As additional discrepancies are

identified that need further evaluation, they are being added to Problem

Report (PR)96-119 for resolution.

The review is scheduled to be

completed in February of 1997.

The resolution of these FSAR

discrepancies will be reviewed during future inspections of the results

of the FSAR Operational Review.

S1.1 Escort Duties (71750)

At approximately 11:45 a.m. on August 14, 1996, while exiting the TSC,

the inspector observed two vendor personnel, one visitor and one escort,

'

with a vending machine, waiting to exit in the hallway between tne TSC

and the TSC diesel generator room. All of the doors from the TSC into

the hallway were closed, and a security guard was unlocking the

i

emergency doors to cne outside to allow the machine to 5e removed.

A) proximately thirty seconds after the inspector enterad the hallway, a

Exit Meeting Summary

X1.1 During an interim exit meeting on August 30, 1996, the Director. Nuclear

Plant Operations questioned Violation 50-302/96-09-05 (relative to the

failure to change procedures after the modification of valve MUV-64)

since the valve lineup procedure was changed to show valve MUV-64 sealed

o]en.

The question was whether a violation existed if this 3rocedure

clange was made prior to identification of this problem by tie NRC. The

inspectors noted that change to the valve lineup procedure, without

additional in w w lons on when and under what plant conditions to

operate the va & does not satisfy the need for additional instructions
