EXECUTIVE SUMMARY

Diablo Canyon Nuclear Power Plant, Units

1 and 2

NRC Inspection Report 50-275/97-016; 50-323/97-016

This inspection included aspects of licensee operations,

maintenance,

engineering

and

plant support.

The report covers

a 6-week period of resident inspection.

~Oerations

In general, operations were conducted

in a conscientious,

competent,

and

professional manner, with focus on safety and procedural compliance.

Operators

were knowledgeable

of plant conditions and activities, and responded

quickly and

properly to annunciators

(Section 01.1).

Observations

were made, which were indicative of a lack of attention to detail in log

keeping in the control room.

Operation logs in some instances lacked sufficient

information, did not document why an action was taken or the outcome of the

action, and clerical errors were found (Section 01.2).

Operators demonstrated

good performance

in the October 3 dedrease

in Unit 1

turbine load from 50 percent to 38 percen't to repair a steam leak.

The down power

was well coordinated, with continuous

and diligent monitoring of the plant

conditions, and timely response

to alarms and indications.

The shift foreman was

clearly in control of the evolution and constantly aware of plant conditions

(Section 01.3).

Operations was effective in maintaining appropriate configuration control of the six

emergency

diesel generators

and their subsystems

and supporting systems.

The

systems were correctly aligned and in compliance with the Updated Final Safety

Analysis Report (UFSAR), Technical Specifications

(TS), and applicable plant

procedures.

The material condition of the equipment was good with only a few

minor equipment problems, which were documented

in Action Requests

(AR)

(Section 02.1).

Quality assessments

of operations during the Unit

1 refueling were effective.

Improvements

in control room formality were noted and the continuing problems

with clearances

were documented.

Areas for improvements were identified,

including performance of risk assessments,

and operators understanding

of the

Maintenance

Rule.

These assessments

were consistent with the findings of the

NRC Maintenance

Rule inspection (Section 07.1).

-3-

Maintenance

Maintenance

personnel were effective in the performance of maintenance

activities.

Personnel

were knowledgeable

of the equipment,

procedure,

and tasks to be

performed, the work documents

and procedures

were in use at the work site, and

required clearance tags were hung (Section M1.1).

A special surveillance test was conducted

in a high quality manner.

Procedure

Surveillance Test Procedure

(STP) M-75, "4KV Vital Bus Undervoltage

Relay

Calibration," previously performed only during shutdown, was performed at power.

The management

briefing covered management's

expectations,

such as the need to

~

exercise caution and conservatism.

The procedure

had been thoroughly reviewed to

ensure the test had no unexpected

impact on the plant (Section M1.2) ~

The plant equipment was well maintained, with an appropriate focus on deficient

conditions.

Existing equipment problems were identified by AR tags and new

problems were reviewed daily and priorities set to ensure quick response to those

problems that could degrade

safety-related

equipment.

The priorities were generally

based on sound conservative judgement (Section M2.1) ~

Encnineering

The Engineering backlog continued to be a challenge for the licensee.

Although the

licensee's efforts had not reduced the number of open items as much as desired,

there was increased confidence that quality issues had been identified and a clearer

understanding

of the priority of the individual issues (Section E6.1).

Plant Su

ort

Radiation protection technicians provided high quality support to operations

personnel

"in performance of the venting of the emergency

core cooling

system

(ECCS). The radiation protection technicians were knowledgeable

of

radiological protective measures,

proficient in handling the vent bottle, hoses,

gloves, rags and waste water, and performed numerous radiation and contamination

surveys (Section R4.1).

General Comments

71707

Using Inspection Procedure 71707, the inspectors conducted frequent reviews of

ongoing plant operations.

In general, operations were conducted

in a conscientious,

competent,

and professional manner, with focus on safety and procedural

compliance.

Operators were knowledgeable

of plant conditions and aware of plant

activities that impacted their work station.

Operators responded

quickly and

Review of 0 erations

Lo s

a.

Ins ection Sco

e 71707

The inspector reviewed Units

1 and 2 Shift Foreman's

Log, Control Operator's

Log,

and Nuclear Operator's

Log for compliance with Administrative Procedure

Operating

Procedure

(OP) 1.DC37, "Plant Logs," Revision 4B.

b.

Observations

and Findin s

Most logs reviewed contained at least the minimum information specified in

Procedure

OP1.DC37.

However, some entries were so brief as to not meet the

intent as described

in the scope section of the procedure.

The procedure stated

that the log should preserve the actions and events of the day and document what

was done, why it was done,-and the outcome of what was done.

For example, on

October 1, the TS 3.7.12 limit on inlet water temperature

was exceeded

and

both units entered the Action Statement,

which is to place a second vital

component

cooling viater heat exchanger

in service within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

The actions of

placing the second train in service were delayed for over 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, in part due to

questions

related to chlorinatiori of the associated

auxiliary saltwater trains.

Neither

-2-

Unit

1 nor Unit 2 Shift Foreman's

Logs, nor Unit

1 or Unit 2 Control Operator's logs

documented

the reason for the delay.

According to Procedure OP1.DC37, the control operator's

log should include

starting and stopping of plant equipment,

and the reason.

The reason was not

always clearly documented.

Several clerical errors, such as checking the incorrect

shift or entering an incomplete date, were identified to the licensee personnel

and

corrected.

c.

Conclusions

tn general, the togs contained the minimum information required by the licensee's

administrative procedure.

In many cases the logs did not document why an action

was taken nor the outcome of the action.

The clerical errors noted were indicative

of a tack of attention to detail in maintaining the plant logs.

01.3

Conduct of Unit 1 Load Chan

es For Steam Leak Re airs

a.

Ins ection Sco

e 71707

On October 3, the inspector observed control room activities dUring load reduction

from 50 percent to 38 percent and return to 50 percent to support repair of an

unisolable leak on an extraction steam line flange.

b.

Observations

and Findin s

Operators performed the load changes

in accordance

with Procedure

OP L-4,

"Normal Operations at Power," Revision 37.

The procedure provided the necessary

directions to perform the required activities.

An additional control operator was

assigned

to assist in the control room during this activity. This was espe=ially

useful to facilitate compliance with the licensee's policy of peer checking each

operation of a plant control.

The additional operator facilitated frequent operation of

the boration and dilution controls, in addition to operation of rod and turbine

controls.

The low value of moderator temperature

coefficient at this time in core life made

reactivity control during the resultant Xenon transient more difficultthan usual.

The

control operator was diligent in monitoring and controlling the reactor while

remaining in control of the load change activities.

The unloading of Main Feedwater

Pump

1-1 was well coordinated

and minimized the effects on the reactor

temperature

and steam generator levels.

The operators

had reviewed the steps in

the procedure,

discussed

the expected

response,

and planned the coordination of

their actions.

The shift foreman initiated each major evolution and was constantly

aware of plant conditions.

-3-

The operators'esponse

to alarms and annunciators

was timely and in accordance

with their annunciator response

procedures.

Communications with personnel

outside the control room was quickly initiated to ensure the necessary

actions were

taken to respond to each new alarm.

In general, the shift foreman and control

operators were well informed of activities in the plant and the effects of those

activities on the control room indications.

c ~

Conclusions

The conduct of ope'rations during the load change was well coordinated, with

continuous

and diligent monitoring of the plant conditions and timely response to

each alarm and indication.

The shift foreman was clearly in control of the unit and

always aware of plant conditions.

The control operator continuously monitored

plant parameters

and maintained those parameters

well within acceptable

limits.

Emer enc

Diesel Generator Walkdown

a,

Ins ection Sco

e 71707

The inspector performed

a walkdown of the six emergency

diesel generators to

verify proper system configuration and equipment condition to support operability.

Procedure

OP J-6B:I, " Diesel Generator

2-1 Make Available," Revision 12, was

reviewed for technical adequacy

and used during the walkdown.

Applicable

sections of the TS and UFSAR were used to assure consistency with plant design

and operation.

b.

Observations

and Findintis

The systerh was aligned in accordance

with operation procedures

and consistent

with the UFSAR and TS. The general condition of the equipment was acceptable,

with minor discrepancies

noted, such as minor lubricant leaks.

Relief

Valve DEG-2-RV-274 on the discharge

line of Air Dryer 2-38 for a starting air

compressor was noted to be missing

a lead seal.

This was identified to the

licensee, who promptly documented

the condition, evaluated it for impact on the

plant equipment,

and identified corrective actions.

The control switches in the control room and in the plant were properly aligned.

Local and remote indications were within acceptable

bands.

Subsystems,

such as

fuel oil, lubricating oil, starting and turbocharger

air, as well as AC and DC electrical

systems,

were also reviewed and found to be properly aligned.

Seated valves were

confirmed to have their seals intact.

Tank levels were verified within acceptable

ranges.

c.

Conclusions

The six emergency

diesel generators

and their subsystems

and supporting systems

were correctly aligned and in compliance with the UFSAR, TS, and applicable plant

procedures.'he

material condition of the equipment was good with only a few

minor equipment problems, which were documented

in AR.

e 71707

The inspector reviewed the position of the Unit 2 ECCS valves listed in Surveillance

Requirement

(SR) 4.5.2 and the status of power to the valves.

Surveillance

Procedure. STP l-1A, "Routine Shift Checks Required By Licenses," Revision 67,

was reviewed.

b.

Observations

and Findin s

The valve were found to be in their required positions as determined by control

room indications or local obser'vation.

The power to the valves was verified to be

removed either by the associated

480 volt supply breaker checkbd in the open

position, or for six valves, by their series contactor cutout switches verified to be in

the open position.

The shift surveillance procedure contained steps to verify the

position of the valves, the position of the associated

480 volt breakers and the

position of the cutout switches.

c.

Conclusions

'Those valves specified in SR 4.5.2.a were in their required position and power was

removed.

The shift surveillance procedure contained steps to meet the SR

on conduct of operations

and command and control of operations.

The assessment

was performed by observing the conduct of operations

and comparing it to written

policy and procedure guidance.

Under conduct of operations,

NQS assessed

control room formality,

communications,

tailboards (preactivity briefings), self-verification, and peer

checking.

A notable improvement in control room atmosphere

(i.e., stress and

congestion)

was attributed to changes

implemented by operations

in control room

formality.

NQS assessed

procedural adherence

by operations, with particular interest in how

operators responded

to unexpected

situations or steps that could not be performed.

Overall, NQS found the procedures

to be adhered to and discrepancies

handled

appropriately.

NQS focused on clearance related errors due to previous problems in this area.

Despite efforts to enhance

the clearance

process,

clearance

related events remained

at a significantly high number.

b.

Observations

and Findin s

Prior to the performance of STP M-89, "ECCS System Venting," operations

performed

a briefing in the control room.

The briefing was thorough, covering'the

scope, responsibilities, interface with radiation protection and control room operator,

precautions

and limitations, as well as the significant procedural steps.

The

operator performed the venting per the procedure,

signing the steps as they were

completed.

The operator used good work practices to prevent spilling of water, to

contain potential contamination,

and to carefully remove and reinstall the pipe caps

to protect the pipe threads.

The venting was successful with little air found.

Procedure

STP V-3R1 was appropriately used as postmaintenance

test for

10 percent dump Valve PCV-22.

The procedure satisfied the TS requirements to

-8-

demonstrate

operability and complied with the Inservice Test Program, Second

10-Year Interval requirements

for stroke timing. The operators performing the test

were knowledgeable

of '.he equipment operation and procedural requirements.

The

operators

used peer checking and three-way communications.

The operators

properly documented

the test results, showing that the valve stroke times met the

TS requirement

and were within the procedure's

ACTION values.

Procedure

STP P-AFW-11 was performed to satisfy the quarterly testing

requirements of TS and the Inservice Test Program.

Operators performing the test

were knowledgeable

and signed the procedure

steps

as they were completed.

The

system engineer was present and assisted.

A small leak was identified in a

coupling in the cooling water line to the turbine bearing.

Maintenance

personnel

tightened the coupling, reducing the leak to

1 drop every 2 minutes, and installed a

catch bag to direct the teakoff to a drain.

An AR was written to repair the coupling

at a later time. The test instruments were within their calibration frequency.

The

test results satisfied the TS and procedural requirements.

Procedure

PEP R-3A, "Use of Flux Mapping Equipment," Revision OA, was

performed by Reactor Engineering to obtain a Unit 2 full core flux map to satisfy the

monthly SR.

The engineers

had identified det'ector drives and paths, which had

previously been difficultto access,

and confirmed that no new f)roblems with drives

were identified.

Procedure

STP M-75, "4KV Vital Bus Undervoltage

Relay Calibration,"

had

previously been performed only during outages.

Its performance at power was

treated as special test in accordance

with AD13.ID1, "Conduct of Plant and

Equipment Tests."

This required

a pretest briefing by management

and Section

Director oversight.

The briefing contained the required information including

management's

expectations,

such as the need to exercise caution and conservatism

during the test.

The test procedure

had been thoroughly reviewed to ensure it

could be performed at power.

The test procedure contained

an attachment to track

the TS actions entered

and exited during the test.

This was beneficial to

operations,

as the test required numerous entries into several TS actions.

One first

level undervoltage

relay was found out of tolerance

and was replaced.

The testing

progressed

well with no unexpected

impact on the plant.

Conclusions

The inspectors found that the surveillances

observed

were being scheduled

and

performed at the required frequency.

The procedures

governing the surveillance

tests were technically adequate

and personnel performing the surveillance

demonstrated

an adequate

level of knowledge.

The inspectors

noted that test

results appeared

to have been appropriately dispositioned.

Maintenance and Material Condition of Facilities and Equipment

M2.1

Plant Material Condition

During routine plant tours, the inspector noted plant equipment to be well

maintained, with minor equipment problems such as minor lubricant leaks to be

identified with a corrective maintenance

AR tag.

Specific equipment inspected,

at

least in part, included emergency

diesel generators,

480 volt vital switchgear,

4160 volt vital switchgear, AFW pumps and associated

valves, ECCS valves

identified in TS 4.5.2, and control room ventilation equipment.

Corrective maintenance

ARs were reviewed in daily meetings where priorities were

set to ensure quick response

to those problems that could degrade safety-related

equipment or equipment needed for continued electrical generation.

The priorities

were generally based

on sound conservative judgement, considering both impact of

removing equipment from service and potential for deteriorating condition.

Unresolved Item

URI 50-275 323 97012-01:

failure to review and

evaluate previous battery operated

light (BOL) failures as maintenance

preventable

functional failures (MPFF).

The BOLs were included in the licensee's

Maintenance

Rule program in February.

Three BOL failures, which occurred in May 1995, March

1996, and January

1997, were documented

on ARs, but the ARs did not include an

evaluation of the failures as MPFFs.

The failure to include the BOLs in the scope of

the Maintenance

Rule from July 10, 1996, until February 1997 has been addressed

in a separate

Mairitenance Rule NRC Inspection Report (50-275;323/97-04).

The BOL system engineer had been reviewing and trending the results of the

maintenance

and surveillance tests on this system to identify performance problems

that may r'esult from service life, maintenance

performance,

or BOL environment.

Upon review of the type and number of equipment problems and the system

engineer's

monitoring of the system performance,

the inspector concluded that the

system engineer,had

reviewed the previous failures and had concluded that the

failures were not maintenance

preventable.

The licensee had demonstrated

effective control through maintenance

such that the BOLs would perform their

intended function and placing the system under (a)(2) of the Maintenance

Rule was

appropriate.

Based upon this analysis, this URI is closed.

The inspector reviewed status reports depicting Nuclear Technical Services'NTS)

backlog of engineering

assigned

ARs and Action Evaluations

(AE).

b.

Observations

and Findin

s

The licensee trended the NTS AR and AE workload.

As of September

22, 1997,

approximately 5000 open AR and AE items were assigned to NTS. This was

approximately four percent more items than in August.

Efforts to reduce the

backlog have had limited success

in reducing total open items.

The licensee

reviewed the ARs and AEs in the backlog to verify the correct identification and

coding of quality issues.

Since quality issues receive quicker attention, this review

was performed to ensure the backlog did not contain misidentified quality issues.

The number of open quality issues have remained

a small percerltage of the total

open workload, and the number of overdue quality issues have remained small.

The ARs and AEs in the backlog were also prioritized for importance (required

verses discretionary items) and the distribution in each priority trended.

A large

number of items were considered discretionary and the licensee initiated an effort to

review and work off this burden.

This effort resulted in many items being more

correctly identified as higher priority.

The items in the backlog were also reviewed for assignment

of due dates consistent

with each item's importance.

Additional effort by NTS has resulted in a significant

reduction in overdue work, dropping from 40 percent of AR/AE in overdue status in

March to 6 percent overdue status in September.

C.

Conclusions

The NTS backlog of ARs and AEs continued to be a challenge for the licensee.

Although the licensee's efforts had not reduced the number of open NTS'Rs and

AEs as much as desired, they had resulted

in increased confidence that quality

issues

had been identified and a clearer understanding

of the priority of

the'ndividual

issues.

The reduction in overdue items and the small number of overdue

quality issues indicated

a better focus of the work effort.
