I. INTRODUCTION

The Systematic Assessment of Licensee Performance (SALP) program is an

integrated NRC staff effort to collect;available observations and data on

a periodic basis and to evaluate licencee. performance based upon this

information. SALP is supplemental to normal regulatory processes used to

ensure compliance to NRC rules and regulations. 'SALP is intended to be

sufficiently diagnostic to provide a rational basis for allocating NRC

resources and to provide meaningful guidance to the licensee's mana

to promote quality and safety of plant construction and operation. gement

A NRC SALP Bot.rd, composed of staff members' listed below, met on August 7,

1986, to review the collection of performance observations and data to

assess the licensee's performance in accordance with the guidance in NRC

Manual Chapter 0516, " Systematic Assessment'of Licensee Performance." A

summary of the guidance and evaluation criteria is provided in Section II

of this report.

II. CRITERIA

Licensee performance is assessed in selected functional areas, depending

upon whether the facility is in a construction, preoperational, or

operating phase. Functional areas normally represent areas significant to

nuclear safety and the environment. Some functional areas may not be

assessed because of little or no licensee activities, or lack of meaningful

observations. Special areas may be added to highlight significant

observations.

One or mere of the following evaluation criteria were used to assess each

functional area.

1. Management involvement and control in assuring quality

2. Approach to the resolution of technical issues from a safety

standpoint

3. Responsiveness to NRC initiatives

'

4. Enforcement history

However, the SALP Board is not limited to these criteria and others may

have been used where appropriate.

'

. Based upon the SALP Board assessment each functional area evaluated is "

classified into one of three performance categories. The definitions of '

these performance categories are.:

Category 1: Reduced NRC attention may be appropriate. Licensee

management attention and involvement are aggressive and oriented toward

nuclear safety; licensee resources are ample and effectively used so that

a high level of performance with respect to operational safety and

construction quality is being achieved.

Cateaory 2: NRC attention should be maintained at normal levels. Licensee

management attention and involvement are evident and are concerned with

nuclear safety; licensee resources are adequate and are reasonably

effective so that satisfactory performance with respect to operational j

safety and construction quality is being achieved. l

Category 3: Both NRC and licensee attention should be increased. Licensee

management attention and involvement is acceptable and considers nuclear

safety, but weaknesses are evident; licensee resources appear to be strained

or not effectively used so that minimally satisfactory, performance with

respect to operational safety or construction quality is being achieved. ,

IV. PERFORMANCE ANALYSIS

A. Plant Operations

1. Analysis

Plant operations during the assessment period consisted of a j

startup from a major outage to replace recirculation system l

piping, 15 months of power operation, and one month of a i

refueling outage (which continues into the next ,issessment

period). Therefore, the analysis for this area involves

activities of the operational staff for various modes of

operation. '

Portions of routine inspections were performed by the resident

inspector covering plant operations. The inspections included

observations of control room operations, reviews of logs,

discussions with licensed and unlicensed operators, verification

of operability of emergency systems, and reviews of reactor

building and turbine building equipment status.

No violations were identified in the operations area. This

is a decrease from the previous assessment period.

Three reactor scrams from power occurred during the assessment

'

period. The first resulted from an offsite power line

transformer being grounded by an electrical maintenance crew .

about 30 miles from the plant. The second occurred during

surveillance testing of the main steam line low pressure

instrument by an I&C technician improperly valving pressure

switches. The third occurred dug to low vessel level after loss

-

of a recirculation pump, and the level transient tripped all

reactor feedwater pumps. These scrams involve personnel and

procedural error, but not on the part of licensed operators.

The scram frequency is less than the industry average. The

unit experienced a record 200-day run which was terminated by

a scheduled refueling outage.

Seven LERs involving personnel error were made during the

assessment period. Of these, one involving the restoration of

an uninterruptable power supply was made by a licensed operator.

The remaining personnel errors will be discussed in the

appropriate functional areas.

The licensee has demonstrated a clear understanding of technical

issues. Conservatism is routinely exhibited during application

of technical specification requirements and in determining

operability of equipment as was evidenced by the ma.cagement

decision to remain shutdown after the last scram to investigate

and repair the cause of increased drywell leakage, although well

below technical specification limits. ,

.

The licensee demonstrated the ability to control and resolve

many technical and operational issues as evidenced by the smooth

progression of the startup after a long shutdown to replace

recirculation piping. The plant operating record is exemplary

with a cumulative availability of 75.6 percent (which includes

the 11.5 month shutdown), which ranks third highest of BWRs in

the nation.

During the assessment period the Emergency Filtration Train (EFT)

was actuated in the emergency mode on 21 occasions. The EFT

system supplies Control Room ventilation, and its actuation is

reportable as an Engineering Safety Feature. These actuations

resulted in 12 Licensee Event Reports (LERs) during the assessment

period. In 1985, 17 actuations occurred, mostly attributable to

detection tape breakage or tape runout. Based on an investigation

of a dedicated system engineer, the licensee took the following

corrective actions: interaction with the supplier of detector

tape for improved quality; biweekly changeout of detector tape;

and cleaning of the detector heads more frequently. In the five

months following this corrective action, EFT actuations had

dropped 41 percent from a frequency-of 1.4 to 0.8 actuations

per month.

During the assessment pericd, 32 percent of the LERs were

attributable to EFT actuations. This short-term corrective

action should reduce the total number of LERs. The long term

corrective action initiated by the licensee was started by a

Technical Specification Amendment request to remove the hydrogen

chloride, ammonia, and hydrogen sulfide detectors. Also the

licensee is studying removing all stored chlorine from the site

tnus allowing removal of the chlorine detectors. These actions

. would sharply reduce the number of unwanted actuations of the

EFT.

The licensee is responsive to NRC initiatives and timely and

technically sound responses are given in all cases. The

operations staffing remains a licensee strength. The control

room operators, shift supervisors and site superintendents are

well experienced and knowledgeable in their duties. The

operations staff has a low attrition rate which has led to the

high experience level currently enjoyed by the licensee. The

licensee has implemented a degree program for senior reactor  ;

operators which will provide experienced operators with the j

opportunity to earn a technical college degree. Management of 1

operations is strong, providing a motivated, experienced, and

successful staff. i

l

Plant management places importance of the professional conduct of l

operating personnel. Control room atmosphere is of a professional

nature. Operators are attentive to their duties, conduct them-

selves professionally, and present a professional image. This

professional atmosphere is enhanced by the design of the shift

-

l 6

.

~

supervisor's office being adjacen't to, but separate from, the

control room. This situation provides an area for maintenance,

surveillance, and engineering, personnel to interact with the

shift supervisors without having to enter the control room. .

Thus, control room traffic is reduced to only necessary personnel.

The plant management has a " black board" policy regarding the

annunciator panels in the control room. This resulted in only

occasional lit annuciators which were typically cleared promptly.

The control board was " black" during the majority of the

assessment period resulting in a high confidence level in

the annunciator functions by the operators.

2. Conclusion

The licensee is rated Category 1 in this area which is the same

as the last assessment.

3. Board Recommendations

None.

B. R_adiological Controls

1. Analysis

Four inspections were performed during the first half of this

assessment period by region-based inspectors. These inspections

included operational radiation protection, transportation,

confirmatory measurements, chemistry / radiochemistry, radwaste,

and radiological environmental monitoring. The resident

inspector also reviewed this area during routine inspections and

performed the only NRC inspections in this area during the second

half of this assessment period. No violations or deviations were

, identified.

Staffing continues to be a licensee strength. The staff is

stable with no significant turnover other than career progression.

The staff size is adequate and authorities and responsibilities

are well defined; this results in generally good performance of i

all the necessary radiation protection, radiochemistry / chemistry, l

and radwaste functions. Nuclear plant helpers were transferred '

to the Radiation Protection Department, creating a more integrated

operation for lLundry processing and decontamination of tools,

equipment, and plant areas. This transfer of responsibility

allows management to prioritize the use of resources from a

radiological standpoint.

Management involvement in this functional area is consistently

evident. Managers and supervisors are closely involved in the

day-to-day activities of the plant. Procedures and policies are

strictly adhered to and records are complete, well maintained,

and available to personnel. A practice implemented during this

assessment period by the licensee has radiation protection personnel

'

.

attending contractors' safety meetings to answer questions and

provide guidance in radiological matters. This practice appears

to have generated an improved understanding and cooperativeness l

on the part of the contract workers. Corrective actions for I

identified problems are prompt and consistently recognize and

address underlying cencerns. Although not specifically reviewed -

this assessment period, audits of the radiation protection ,

program have historically been conducted annually and have been

complete, timely, and thorough. A licensee audit of the

Radiological Environmental Protection Program (REMP) contractor's ,

performance identified a need to use the proper LLD values, which '

has since been corrected. None of the findings in the audit

indicated that the REMP failed to meet applicable technical

specification requirements; all findings have been closed in a

timely manner.

Responsiveness to NRC initiatives has been good during this l

assessment period. The licensee initiated aggressive contaminated j

aree and solid radwaste reduction programs. A significant j

reduction in contaminated areas, and contamination levels in the

remaining contaminated areas, has resulted. Some of the released

areas had been contaminated since early in plant operation. In

addition to the decontamination activity, modes of contamination

spread were identified and appropriate corrective actions taken ,

to reduce future contamination spread. The solid radwaste

reduction program incorporates administrative controls over '

introduction of waste material into potentially contaminated

areas and over equipment and tool use.in potentially contaminated

areas, and use of improved volume reduction equipment. The solid

radwaste reduction program has helped reduce the volume of

radwaste from 43,000 cubic feet in 1984 to 19,000 cubic feet in

1985, and has a 10,000 cubic feet goal for 1986. The licensee

has also demonstrated responsiveness to inspector concerns by

completing a procedure on waste classification which documents,

verifies, and incorporates a procedure for waste classification

computer programs, and by modifying the waste radioactive

material shipping procedure to include reference to the new

radwaste requirements.

A conservative approach to resolution of radiological control

issues is routinely exhioited. Personal radiation exposures

for 1985 were 310 person-rem which is significantly below the

800 person-rem average for U.S. boiling water reactors. The

licensee continued to upgrade its ALARA program during this

assessment period. A new ALARA program document has been written

and a committee chartered consisting of top plant management for

plant ALARA decisions. A new ALARA checklist was developed and

department goals have been established. In order to reduce

internal radiation exposure potentials, tne licensee has

purchased and set up positive containment systems for

contamination control.in the Control Rod Drive Rebuilding

and Transversing Incore Probe Drive areas.

.

The licensee continues its conservative policy of prohibiting

routine liquid radioactive releases. Waste liquids are recycled

for reuse in the reactor coolant system or used in processing

solid wastes. An unusually large amount of waste water, about

800,000 gallons per u nth, was processed during the major main-

tenance outage which ended early in this assessment period.

Gaseous effluent releases remained lower than average for U.S.

boiling water reactors primarily due to the licensee's offgas

system design which utilizes waste gas storage tanks, and to

licensee efforts to maintain low condenser air in-leakage

(4-5 cfm). The number of solid radioactive waste shipments were

about average for U.S. boiling water reactors. The licensee is

satisfactorily implementing the requirements of 10 CFR 20.311 and

10 CFR 61 applicable to low-level radwaste classification, waste

form, and stabilization. No problems have been associated with

the licensee's radwaste shipments. The licensee also made

18 shipments of spent fuel to the GE-Morris storage facility

without incident during this assessment period.

.

Licensee chemistry and radiochemistry programs were well

implemented during this assessment period. The licensee's

laboratory chemical instrumentation is being upgraded with the

. purchase of an atomic absorption spectrophotometer and an ion

chromatograph for analysis of nonradiological key chemical

parameters to maintain tight chemistry control.over plant systems.

'

The licensee has recently prepared two procedures describing

<

their QA/QC programs for chemistry and has begun to implement

these programs. They involve instrument calibration and calibra-

tion verifications, testing the proficiency of the Radiation

Protection Specialists (RPS) for non' radiological samples by  ;

providing them with blind samples on a periodic basis, and

requiring the RPSs to participate in an interlaboratory round .

robin analysis program. A weakness in this area is the lack'of .

licensee participation in the cross check program for

radiochemical analyses.

Confirmatory measure.nent results during this assessment period

have declined in performance since the previous period in 1983.

The licensee had 33 agreements out of 40 comparisons. The

licensee, where possible, made timely and prompt corrections

during the analyses, such as correcting gamma spectroscopy

software to resolve one disagreement. However, the licensee

appears to have some difficulty in performing beta analyses

with disagreements for tritium, strontium-89, and gross beta

in two split samples and with disagreement for strontium-89 in

a spiked sample sent from the NRC Reference Laboratory.

Outside of the fact that in a few instances the licensee used

improper lower limits of detection (LLD) values during the first

quarter of 1983, when the new Radiological Effluent Technical

Specification became effective, implementation of the REMP has

been generally satisfactory. The licensee's contractor continues

to follow good quality control practices through participation

in the EPA cross check program and an international comparison

maintains trend plots of REMP sample dat'a indicating an' i

appropriate assessment for data review. No environm' ental

'

trends attributable to plant operation were identified.

The licensee is rated a Category 1 in this area. The licensee's l

performance in confirmatory measurements which has declined i

somewhat during this assessment period. l

C. Maintenance

1. Analysis

Portions of nine routine inspections were performed by the

resident inspector covering this area. The inspections included

reviews of normal maintenance and modification activities to

ensure that approvals were obtained prior to initiating work,

activities were accomplished using approved procedures, post

maintenance testing was completed prior to returning components or -

systems to service, parts and materials were properly certified.

In addition, four inspections by regional-based inspectors were

performed in this area. These inspections examined the functional

testing and maintenance of safety-related snubbers, resolution of

. IE Bulletins',-licensee actions related to previous inspection

findings, a'10 CFR 71 report, and the review of items of concern '

'

related to the replacement of Recirculation and Residual Heat

Removal system piping. In addition, work planning and scheduling

was reviewed as well as the effectiveness of administrative

controls to ensure proper priority is assigned. '

No violations were identified in this area. Equipnent problems

caused a small number of LERs which were promptly corrected.

The long continuous run after the extensive work on the  :

Recirculation and Residual Heat Removal system supports a

conclusion that maintenance is of a high quality. The low

number of forced outages is also an indication that maintenance

is of a high quality.

The regional-based inspectors concluded that several of the

contractor employee concerns related to the replacement of the

Recirculation and Residual Heat Removal system piping were

substantiated. The substantiated concerns were: (1) that soft

copper tubing was used to deliver argon gas to the weld area,

review *

of all the concerns concluded that the quality of the installed  ;

piping was not affected.

The visual inspection of snubbers and the evaluation of snubber i

testing were generally controlled through the use of well stated '

and defined procedures that were adhered to. The licensee's i

actions to resolve previous inspection findings were timely,

workable and technically sound. The approach used to evaluate '

and resolve IE Bulletins and a 10 CFR 21 report were conservative,

technically sound, and thorough. Deadlines were met and there

was timely resolution of issues.

Policies were well stated and understood, and decisionmaking

consistently was at an appropriate management level. When

problems arose, the licensee applied technically sound and

thorough analyses in solving them. They were responsive to

to NRC concerns and gomptly reported events that needed

reporting. In addition, the work reouest authorizations and

tagouts used by the licensee indicated that maintenance

activities were under strict control. For the areas examined,

the instector

i determined that the management control systems

met regulatory requirements, and that personnel, equipment,

and material certifications were current and complete.

.

Discussions with licensee and contractor personnel indicated

that they were knowledgeable in their job. Observations

indicate personnel had an adequate understanding of work

practices and adhered to procedures.

.

The number of systems tagged out for maintenance during the

15 month assessment period was extremely low. During power

operation, from routine control room panel surveys, typically

no systems were tagged out for maintenance. On occasions where

equipment was tagged out, it was promptly restored. The number

of work requests has been at a manageable level throughout power

operation.

Permanent maintenance staffing is adequate with low attrition.

This has provided experienced personnel who are knowledgeable in

the performance of their duties. This experience and ability has

contributed to the success of the maintenance program.

2. Conclusion

The licensee is rated Category 1 in this area which is the same

as the last assessment.  ;

D. Surveillance and Inservice Testing

1. Analysis 1

During the assessment period, the resident inspector routinely

inspected this area. These inspections included observations

of technical specification required surveillance testing to

verify adequate procedures were used, that instruments were

calibrated, and that test results conformed with technical

specification and procedure requirements. In addition three

regional inspections were conducted in this area. These

inspections included startup core performance and Containment

Integrated Leak Rate Tests (CILRT). Four violations were

identified as follows:

a. Severity Level V - Failure to develop, implement, and

maintain a program for the control and calibration of

. timing devices; i.e., stopwatches (263/85012).

b. Severity Level IV - The CILRT procedure was inadequate and

failed to meet the requirements of technical

'

specifications (263/84026).

c. Severity Level V - The licensee failed to correctly total

the isolation valve leakages as required by technical

specifications (263/84026).

d. Severity Level IV - The licensee failed to determine the

as-found containment leakage (263/85025).

Violations, Items b. through d. are evidence of a weakness

ident'. Tied in corporate management involvement in containment

leak rate testing activities. Specifically, a violation was

issued to the Monticello facility for failure to properly

incorporate local leak rate test results into the integrated

test result. This issue had been addressed appropriately at

.the utility's other nuclear plant, Prairie Island, since 1977.

This disparity in practices is indicative of a need on the part

of corporate management to become more involved in activities

common to both their facilities. l

The licensee has a well managed surveillance scheduling program.

Two LERs resulted from missed surveillances; one was due to a

missed sampling of fuel oil and the other was a missed fire l'

protection water header flush. No surveillances were missed

due to scheduling problems. The fixed surveillance schedule is i

evidence of management's dedication to performing surveillances

on a routine basis. Surveillance procedures are well written

and adhered to by the cognizant personnel. Management

involvement supports the surveillance program.

~

There were several personnel errors associated with surveillance

during the assessment period. One resulted in a scram during

Main Steam Line Low pressure instrument testing. Three LERs

involved testing of radiation monitors. The licensee is

installing test switches in several of the radiation monitor

circuits which will allow testing without the need of jumper

installation. This modification will allow testing in a manner

much less prone to error. More attention to detail could result

in a lower number of occurrences. The Instrument and Control

(I&C) personnel are well trained, and the I&C staff has a low

attrition rate resulting in an experienced complement of

technicians. The staff complement is adequate and continues

to improve by hiring additional personnel of a high technical

education level. These personnel are placed in an effective

on-the-job training program.

2. Conclusion

The licensee is rated Category 2 in this functional area which

is the same as the previous assessment period.

3. Board Recommendations

None.

E. Fire Protection

,

'

1. Analysis

During this assessment period, the resident inspector performed

routine inspections in this area, including evaluation of

potential fire hazards, plant housekeeping and cleanliness, and

compliance with the plant fire protection plan. The inspections

showed a significant improvement in housekeeping in the latter

part of the assessment period. The licensee has established a

three year painting and preservation plan for the reactor and

turbine buildings. This program will further improve the current

high standard of housekeeping and cleanliness.

Appendix R requirements haw bean completed with the exception of

the Alternate Shutdown Panel which is currently being installed

during the ongoing refueling outage. The plant will be awaiting

NRC inspection of its Appendix R modifications when this last

action is complete.

One LER as previously discussed in the Surveillance Section was

reported during the assessmant period regarding this area. It

involved missing a new technical specification surveillance

requirement to flush a turbine building fire suppression header.

This section of header always had an alternate source of water,

thus the significance of this event was minimal. No violations

or other LERs were identified during the inspection period.

13

._ _

. .

.

.

.

One minor fire occurred during the assessment period. This was

caused by welding sparks igniting a plastic bag lining a rubbish

barrel. The fire watch extinguished the fire, but failed to

inform the control room, After this event, the plant manager by

letter, required all contract laborers to receive additional

training on fire watch duties within one week. Procedures were

modified to more clearly define and establish fire protection and

fire watch training. This event identified an inadequacy in the

training of fire watches, and the corrective action was complete

and thorough. The strong corrective action taken is indicative

of the management's conservative attitude and approach toward

fire protection.

During the assessment period the licensee significantly

improved housekeeping. The Reactor and Turbine Buildings had

some areas which were cluttered by temporary storage. This

effort to clean out was hampered by contamination of some

material. The licensee allocated the necessary resources to

decontaminate and clear out these areas. Many areas which were

used as temporary storage for the life of the plant are now

uncluttered.

The licensee's actions in housekeeping were recognized by their

fire insurance carrier. This led to a significant reduction in

Monticello's insurance premium during the assessment period. .

Management has initiated action to hire a fire protection

engineer. This staffing will enhance the licensee's fire

protection program.

The inspector observed several fire drills during the assessment

period. The fire brigade response was timely and effective in

all cases. Fire brigade training is held annually at a fire

fighters training facility in the area and provides an excellent

training program for fire brigade members.

!

The licensee resolved technical issues with appropriate  !

justification and documentation and was enthusiastically '

cooperative with regard to concerns raised by the NRC.

Response time was appropriate and communications were

positive.

Visits to the plant by NRR representatives also concluded that

the plant had a clean, well ordered appearance. The workers

have been observed to behave in a disciplined manner in confor-

mance with good housekeeping practice.

2. Conclusion l

The licensee is rated Category 1 in this area. This is an

improvement over the last assessment period in which a Category 2

with an improving trend was received.

F. Emergency Preparedness

1. Analysis

Two inspections were performed during the assessment period, and

both of these were evaluations of annual emergency preparedness

(EP) exercises. One was conducted on December 5, 1984 and the

other on October 9, 1985. Two weaknesses were identified during

the 1984 exercise and one during the 1985 exercise.

The two 1984 weaknesses involved improper exercise controller

techniques in the Control Room and the Emergency Operations

Facility (E0F) and inadequate contamination control at the Access

Control Point and at the entrance to the E0F. Both of these items

were closed by successful demonstrations in the 1985 exercise as

evaluated by the inspectors.

The 1985 exercise weakness concerned improper removal of

protective clothing by an emergency worker when leaving a

radioactively contaminated area (simulated). This weakness

will be evaluated in the 1986 exercise.

'

The 1984 exercise included a successful demonstration of a shift

change and shift augmentation. This shift change demonstrated

that required emergency response personnel, after being notified

to report to the plant, could function as an operational unit in

the Control Room, Technical Support Center (TSC), Operational-

Support Center (OSC) and E0F within the required activation

times. The capability to calculate and evaluate dose assessment

projections using the Meteorological Information aiid Dose

Assessment System (MIDAS) was adequately demonhtrated in the E0F

in the 1984 exercise. This was in contrast to an inadequate

demonstration in the 1983 exercise. This improvement in dose

assessment capabilities indicated improved training and a sound

approach to resolve this technical issue through better

understanding of the MIDAS user.'s manual in conjunction with

the emergency implementing procedures.

Correction of prior exercise weaknesses and general improvement

in other emergency preparedness areas indicated the training

program is well defined, responsive to EP issues, and implemented

with dedicated resources to adjust and reemphasize certain facets

of the EP training program when required. Decision making

has been consistently at a level that ensures adequate maningement

review.

Since annual emergency exercises rarely result in violations,

there has been no means to judge enforcement history with I

routine inspections not scheduled in the SALP 6 period. Three

significant events occurred concerning the Public Alert and

-

Notification System which provides 58 warning sirens within the

10 mile Emergency Planning Zone (EPZ) around the Monticello site.

All 24 sirens in Sherboune County failed on the monthly testing

dates in March, April, and June 1985. All sirens were repaired

and made operable in each instance in a timely manner. To detect

circuitry failures on a more frequent basis, the licensee has

installed a receiver in the Technical Support Center which

receives a signal indicating whether the circuitry is functional

or not. This test is done weekly except for the one week each

month when a full alarm test is made on all sirens. There have

been no further instances of all 24 sirens failing at one time

since June 1985.

Overall, the licensee is continuing to improve the emergency

preparedness program through attention to quality and

responsiveness not only to NRC recommendations but also to their

own drill and exercise critique findings. The licensee has

maintained a positive and cooperative attitude towards improving

all phases of the EP program.

2. Conclusions

The licensee is rated Category 1 in this area. This is the same

rating as the previous SALP assessment.

G. Security

1. Analysis

One routine physical security inspection was performed early in

the assessment period by a regional based inspector. The

resident inspector also made periodic inspections of security

activities and assessed routine program implementation. No

violations were identified by region or resident inspector

relative to the security program. 1

Senior management continues to have an awareness of security  ;

issues and is effective and responsive to resolving security l

issues as demonstrated by the lack of violations reported or

identified during the previous and present SALP periods.

Excellent management support exists at both the site and

.

corporate management levels as demonstrated by the close

coordination between the corporate and site offices. Senior

-

security personnel have a high degree of expertise and have

been effective in identifying problem areas and recommending

solutions. Concerns and observations receive the same

exceptionally high. level of management attention normally

associated with violations, and management is responsive to all

findings that can strengthen their security program.

There were no technical security issues with respect to plant l

safety that required resolution during the assessment period, nor .

were there any regulatory issues identified which required a l

licensee response. I

Security events were properly and adequately reported under

10 CFR 73.71(c). There were 14 such events during the assessment

period. These events pertained to computer related problems and

bomb threats. The computer problems were adequately resolved and

the individual who made the bomb threats was identified,

arrested, and determined by police and hospital professionals not

to be a threat to the plant. Corporate and site security manage-

ment have been aggressive in resolving the computer problem and

the communicated threats to the plant.

, The licensee's staffing levels are adequate to fulfill security

plan commitments and the training and qualification program is

well defined and implemented with dedicated resources which make

a positive contribution to overall implementation of the security

program.

In summary, the licensee's security staff has been effective in

the operation and implementation of the security program. The

security staffing is adequate and departmental support for the

security program has been effective. Supervision of the security

force remains aggressive which results in a stable, well trained

security force.

2. Conclusion

The licensee is rated Category 1 in this area which is the same

rating given in the previous assessment period.

3. Board Recommendations

None.

H. Outages

1. Analysis

The resident inspector performed routine inspections during

>

outages. These inspections included observation of maintenance

activities, review of planning activities, refueling activities,

startup from a 11.5 month outage, review of various modifications

17

  • -

-

.

.

installation and post outage testing. tilso activities were

observed during four short outages for various maintenance

concerns. In these inspections no violations were identified.

Refueling activities were conducted in an excellent manner.

The core was off loaded and reloaded without difficulty.

Communication between the control room and refueling floor was

excellent. The licensee's use of experienced licensed operators

and senior operations personnel in refueling greatly contributes

to the plants traditionally successful operation in this area.

The use of three experienced full time schedulers has resulted in

good programmatic knowledgeable planning which accurately predicts

work requirements. This precision scheduling allows a well

orchestrated array of coordinated work activities. The effec-

tiveness of the schedulers is demonstrated by the cooperation

they receive from managers of all disciplines during daily outage

meetings. This results in cooperation and resolution to various

concerns. Delays due to lack of coordination are rarely

encountered. Corporate management is kept informed by frequent

plant visits and discussions with plant management.

The long continuous run after the extensive work on the

Recirculation and Residual Heat Removal system supports a

conclusion that post outage testing is of a high quality.

The licensee demonstrates a clear understanding of technical

issues, and conservatism is normally exhibited. This is

demonstrated by the licensee's response to concerns identified

by the NRC regarding the stub shaft assembly of the emergency

diesel generators. Although on short notice, the licensee chose

to replace the stub shafts of both emergency diesel generators

during the ongoing refueling outage.

'

Staffing is adequate with contractor support required during

outages and to support modification work. Key positions are

identified and responsibilities are defined. The licensee

utilizes an acceptable level of contractor work force and

integrates the contractor and utility work force in a controlled

manner.

2. Conclusion

The licensee is rated Category 1 in this area.

3. Board Recommendations

None.

I. Quafity Pro' gram and Administrative Controls Affecting Quality

-

1. Analysis

During the assessment period, the resident inspector routinely

inspected this area, which included administrative controls for

maintenance, operations, surveillances, and training. In

addition the Quality Assurance Plan was examined regarding'

the QA audit program at Northern States Power Company's

Corporate office by a regional specialist. Also a

regional inspection of procurement activities was performed.

The resident inspector periodically reviewed QA audits and any

associated findings. One violation was identified in this i

functional area as follows:  !

Severity Level IV - Failure to carryout procurement

activities in accordance with the QA manual.(263/85004).

>

The violation with nine examples was indicative of corporate

management's failure to adequately control site procurement

activities as evidenced by poorly understood policies and

procedures, incomp,lete records, and inadequate procedures.

While the procurement program was neither properly documented

nor implemented in accordance with the existing written program,

no examples were identified where the practices led to installa-

tion and use of substandard material. This item remains open

pending verification of the licensee's corrective actions during

a future inspection.

In regard to the corporate office visit, the inspector determined

that audits were being conducted on schedule, records were

complete, and management at both the site and corporate level

were frequently involved in this activity. Audit reports and

corrective action for audit findings were completed on a timely

basis. Personnel who participated as auditors were qualified.

During the 1986 refueling outage three events occurred which

resulted in NRC attention: inoperability of IRM trip functions

on one channel; squib valve detonator shortening; and LPCI loop

selection design problems. The three events resulted from design

deficiencies. The licensee did not have previous knowledge of

the IRM and LPCI loop select problems. The SBLC problems,

resulting from squib valve detonator shortening, was prenoticed

by the NRC and GE. The licensee did not adequately respond to

these notices.  ;

1

Administrative control procedures provide for effective l

management control, verification and oversight activities. The l

licensee has a well developed, effective plant staff. During the '

assessment period nine LERs were attributed to procedural ^ errors.

The most significant of these allowed flow through the Residual

.

Heat Removal (RHR) intertie line while at 100% power. During th.e

1986 refueling outage a high number of LERs occurred. Although

the outage extends into the next assessment period, it is ,

appropriate to identify'a concern regarding the number of LERs

attributed to procedural inadequacies which occurred during

'

the outage. The licensee has identified this area of concern

-

and has implemented preliminary corrective action in this area

to improve second level review. The licensee is developing this

second level review to be an independent walk-through of the

procedure. This corrective action should be adequate to correct

this concern.

The Operations Committee and Safety Review Committee review of

plant activities is detailed and effective. Control of the

design change process is generally good. Recent~ changes to the

process to improve control and documentation of the construction

work and drawings and procedure changes appear to be effective.

Corrective action systems are excellent in identifying and

documenting events / problems. The root cause and corrective

actions are well developed. Requirements for records are

adequate. No problems with incomplete or inaccurate records

were observed during the assessment period.

Decision making is usually at a level that ensures adequate

management review and corporate management has strong involvement

in site activities. -

During the SALP period, 51 licensing actions were completed

which consisted of 28 plant-specific actions, 13 multi plant

actions, and 10 TMI (NUREG-0737) actions.

b. Management nvolvement and Control in Assuring Quality

During the present rating period, the licensee's management

demonstrated active participation in licensing activities

and kept abreast of all current and anticipated licensing

actions. Licensee management actively participated in an

effort to work closely with the NRC staff to establish

realistic schedules for all modifications of the Monticello

facility. In addition, management's involvement in

licensing activities assured timely response to the

requirements of the commission's rules related to Fire

Protection and Environmental Qualification of Electrical

Equipment.

As presented above, there have been a significant number of

licensing actions processed, and for the most part, the

majority were completed requiring little or no additional

information or meetings. The refueling outage for Cycle 11

operation was for a long duration and overlapped the SALP 6

rating period. The major work completed during this outage

was the replacement of all recirculation system piping

susceptitile to intergranular stress corrosion cracking

(IGSCC) and completion of major Mark I containment

modifications. All modifications related to TMI action

items have been completed except for the installation of

an alternate shutdown panel, which is in the process of

being installed in the current outage. It will be operable

prior to restart. The licensee's management took an

aggressive part in assuring the satisfactory completion of

the above stated tasks and exercised good control over its

internal activities and its contractors to assure quality,

and maintained effective communication with the NRC staff.

22

. .

,

'

c. Approach to Resolution of Technical Issues from a

,

Safety Standpoint

The licensee's management and its staff have demonstrated

technical understanding of issues involving licensee

,

actions. Its approach to resolution of technical issues has

demonstrated adequate technical expertise in all technical

areas involving licensing actions. The decision related to

licensing issues have exhibited conservatism in relation to

significant safety matters, such as early replacement of all

piping susceptible to IGSCC, and completion of environmental

qualification of almost all electrical equipment important

to safety.

On occasions when the licensee deviated from the staff

guidance, the licensee has consistently provided good

technical justification for such deviations. The Fire

Protection Program and the deviation from shift staffing

rule are good examples illustrating the soundness of

technical justifications for deviations from staff

guidance. .

d. Responsiveness to NRC Initiatives

'

The licensee has been responsive to NRC initiatives. During

the rating period, it made reasonable efforts to meet or

exceed commitments. Responsiveness by the licensee facili-

tated timely completion of staff review of a large number of

licensing actions and thus substantially reducing the

licensing backlog. The licensee's quality of license

amendment requests, especially the "no significant hazards

consideration" improved significantly after the counterpart

meeting held on January 30, 1986 in Bethesda, where this

topic was discussed in detail. The licensee has responded

promptly and accurately to various surveys conducted during '

the reporting period. I

1

e. Staffing

The licensee has maintained adequate licensing staff to

assure timely response to the NRC needs.

)

During this period, the licensee's performance with regard to

licensing activities was found to be above average to excellent

overall. Management attention and involvement was generally

aggressive and disciplined. This was evident by the record run.

Staffing levels and quality were adequate. The licensee has

been, in most cases, effective in dealing with significant

problems and NRC initiatives. The licensee's efforts in the

functional area of Licensing Activities has significantly

improved during this evaluation period. This is reflected in

23

' '

the quality of wqrk, attention to NRR concerns, and involvement

of senior management. Monticello was an active carticipant at

the counterpart meeting of January 30, 1986, in Bethesda,

Maryland. This meeting was to discuss common concerns between

Mark I reactors in BWR Project Directorate 1.

2. Conclusion

The overall rating for this functional area is Category 1.

3. Board Recommandations

None.

K. Training and Qualification Effectiveness

1. Analysis

Resident and regional inspectors have evaluated training and

qualification effectiveness during inspection of specific

program areas. No violations were identified in this area.

During inspection of operations activities, non-licensed

operators, control room operators, senior control room operators

(shift supervisors and site superintendents), and shift technical

advisors were knowledgeable and effective in carrying out their

duties.

During the assessment period, NRC examinations were administered

to three Reactor Operator candidates and 14 Senior Reactor

Operator candidates. Two Reactor Operator candidates and

11 Senior Reactor Operator candidates. passed the examinat. ions.

This passing rate is equal to the overall national average

passing rate. Based on these results, the operator licensing

, training program at Monticello is considered satisfactory.

During inspection of maintenance and outage activities,

instrument and control technicians, electrical maintenance

personnel, and mechanical maintenance personnel were highly

knowledgeable of their responsibilities. The knowledge of the

. technical staff and managers remains at a high level. The

licensee sends as many of the technical staff to Senior Reactor

Operator training as possible. This takes knowledgeable

individuals away from the organization for long periods of

time, but in the long run this practice will retain the high

knowledge and experience level of the staff.

During inspection of the radiological protection area, a

regional inspector evaluated training and qualification

effectiveness. Licensee training and qualification programs

generally improved during this assessment period. A step

24

t

training program for new chemist and health physics radiation

protection specialists was implemented. The training program

consists of practical and academic tasks and represents the

management's commitment to provide well trained chemist and HP

radiation protection specialists for future needs.

Management's commitment to provide qualified competent

personnel to operate the facility is evidenced by the low

number of personnel errors during the assessment period. The

training staff provides an effective training program to all

disciplines which is implemented by experienced personnel. The

Monticello training staff has a good working relationship with

the plant staff. This has enhanced the training effort and is

a part of the effectiveness of the training program.

The licensee is making good progress towards INP0 accreditation

of training programs. Accreditation of the Senior Reactor

Operator, Reactor Operator, Requalification, Non-licensed

Operator, and Maintenance (Electrical and Mechanical) programs ,

was achieved on February 19, 1986; and the licensee is projecting

the remaining training programs will be ready for accreditation

-

by September 1986.

V. SUPPORTING DATA AND SUMMARIES

A. Licensee Activities .

The unit engaged in routine power operation throughout most of SALP 6.

A scheduled outage for plant Recirculation and Residual Heat Removal

system piping replacement and subsequent refueling was in progress

at the beginning of the assessment period and was completed on

January 20, 1985. The next refueling outage began on April 30, 1986

and was in progress at the ending of the assessment period.

The remaining outages throughout the period are summarized below:

January 26-27, 1985 Miscellaneous maintenance

May 3-8, 1985 Turbine and control rod drive

maintenance

May 15, 1985 Generator taken off-line to

investigate generator field

ground

July 30, 1985 . Repaired reactor building closed

cooling water leak

October 12-13, 1985 Replaced safety relief valve

top works and miscellaneous

maintenance

The plant scrammed three times during this assessment period. This

reactor trip frequency is much less than the national average. The

first one was caused by a failure to remove grounding cables after

completion of maintenance on an offsith substation transformer by a

non plant worker. The second scram was caused by a personnel error

during performance of a main steam line low pressure instrument

surveillance. The third scram was caused by inadequate procedures

for recirculation motor generator brush replacement.

B. Inspection Activities

No team inspections or planned emergency preparedness exercises were

conducted during this period.

Violation data for the Monticello plant is presented in Table 1,

which included Inspection Reports No. 84026, 84027, 84029-86003.

  • Proximate cause is the cause assigned by the licensee

according to NUREG-1022, " Licensee Event Report System."

    • NUREG-1022 only requires a cause code for component failures.

. In the SALP 5 period, the licensee issued 44 LERs in 17 months

for an issue rate of 2.6 per month. In the SALP 6 period the

licensee issued 37 LERs in 18 months for an issue rate of 2.1

per month. This reduction in issue rate is indicative of an

'

improving trend.

Twelve of the LER$ were submitted for various EFT actuations

due from problems with the Chlorine Monitors. The licensee has

visited the manufacturer's facility in an attempt to resolve the

tape quality problem. The licensee is also submitting a license

amendment request to remove these monitors. Ten of the reports

were due to SBGT initiation for various reasons. Three were

related to scrams. Three were due to component failures; two *

, relay failures and the HPCI flow controller. Two were caused by

missed surveillances. The remaining seven were due to various

causes; RPS actuation due to a spurious IRM spike during testing,

failure to test five TIP penetrations, flow through the RHR

intertie run, ESF bus transferred to auxiliary, both diesel

generators starting, UPS transfer to alternate power source,

,

and trip of shutdown cooling during the CILRT.

i

None of the reportable events were considered individually

significant enough to warrant detailed NRR staff followup.

None of the events included in this SALP evaluation were

discussed at the Operating Reactors Events Briefings.
