EXECUTIVE SUMMARY

IIADDAM NECK PLANT INSPECTION 93-03

Plant Operations

The inspectors noted safe plant operation during the report period and determined that

,

operators performed routine duties very well. Operators also performed well to complete a

plant down power to 60% for a maintenance activity, and in completing a reactor startup.

The inspector noted that improvements in the operator requalification program contributed to

operator proficiency in the conduct of operations outside the control room for postulated fire

,

scenarios.

Operator response to a rod drive system malfunction was timely and appropriate in manually

scram the reactor. ' During the ensuing transient, the operators responded very well to isolate

the high pressure steam bypass system to minimize a plant cooldown and avert an unneces-

sary safety injection.

Licensee actions were timely and thorough to prepare for a potential job action by the plant

work force, and to assure adequate staffing and continued safe plant operation during a

blizzard.

,

The inspector reviewed the service water system and determined that the system was

properly aligned to provide the intended safety function, and that the system was properly

maintained and tested to assure continued operability.

Maintenance

The inspector determined that the performance by maintenance personnel to correct degraded

equipment conditions during the period was very good. In particular, licensee actions were

appropriate and thorough to troubleshoot and repair control rod position indication and

control problems.

Engineerine and Technical Supnort

CYAPCo identified leaks on the six inch service water supply header to the 'B' emergency

diesel generator. The inspector determined that engineering support was good to pmmptly

characterize the defect and assess the structural integrity of the safety class 3 piping. The

inspector further noted that the licensee provided an acceptable operability determination for

the system while processing a relief request from the ASME code requirement in accordance

with Gencric Letter 90-05.

.

The reactor loose parts monitoring system is used at Haddam Neck to monitor vessel noise

i

and to assess the potential for loose parts within the reactor. The system was installed as a

licensee initiative in 1987 and there are no regulatory commitments regarding the installation

or use of the system. However, NRC inspection determined that the licensee could improve

the operation and calibration procedures for the system, and the training provided to

instrumentation specialists.

Safety Assessment and Ouality Verification

The inspector reviewed licensee preparations for the refueling outage including: planning and

scheduling; the development of an administrative control procedure; the deferral of certain

l

modification and maintenance work; and, actions to address shutdown risk. The licensee's

creation of an outage safety assessment team, and the development of prescriptive shutdown

l

safety function requirements are a good initiative. Previously established milestones for

l

outage scheduling were delayed. The effectiveness of outage planning and scheduling

!

changes will be reviewed during of the upcoming outage starting on May 15,1993. The

inspector determined, based on a review of selected plant modifications that will be deferred,

that reasonable engineering justification exists for postponing the work.

SUMMARY OF FACILITY ACTIVITIES

The unit operated at full rated power from the start of the inspection period until March 15,

when load was reduced to 60% to remove from service and inspect the 'B' main feedwater

pump motor. A loose motor shroud gasket was identified and removed on March 15. The

plant returned to full power on March 17 following cleaning of main condenser tubes. Full

power operations continued until March 23, when the operator manually scrammed the

reactor in response to a malfunction in the rod control system. The plant shutdown ended a

370 day operation run for Haddam Neck.

After repair of the rod control system and other maintenance work, the reactor was restarted

on March 24 and full power operation resumed on March 26,1993. The plant remained at

full power for the remainder of the period. On March 27, the licensee conducted an

Emergency Plan exercise that involved partial participation by offsite authorities. NRC

review of the exercise is documented in inspection report 50-213/93-02.

!

On March 5,1993, CYAPCo management announced the following plant organization

changes, effective March 28,1993: Mr. G. H. Bouchard, Haddam Neck Unit Director was

appointed Northeast Utilities Service Company (NUSCo) Director of Quality Services;

Mr. D. J. Ray, Haddam Neck Nuclear Services Director,was be appointed Unit Director;

Mr. J. J. LaPlatney, Haddam Neck Operations Manager will be promoted to Nuclear

Services Director. CYAPCo cited its continuing efforts to maintain and assure safe and cost

effective operation of the unit, and to provide personnel development opportunities, as the

reasons for the changes.

2.0

PLANT OPERATIONS (71707,93702,92709 and 71710)

The inspectors routinely reviewed plant operations during normal utility working hours, and

portions of backshifts (evening shifts) and deep backshifts (weekend and night shifts).

Inspection coverage was provided for forty hours during backshifts and thirty-two hours

during deep backshifts.

2.1

Operational Safety Verification

This inspection consisted of selective examinations of control room activities, operability

reviews of engineered safety feature systems, plant tours, review of the problem identifica-

I

tion systems, and attendance at periodic planning meetings. Control room reviews consisted

of verification of staffing, operator procedural adherence, operator cognizance of control

room alarms, control of technical specification limiting conditions of operation, and electrical

distribution verifications. Administrative control procedure (ACP) 1.0-23, " Operations

Department Shift Staffing Requirements," identifies the minimum staffing requirements.

.

During this period, the inspectors noted that the control room staffing during power opera-

tions met these requirements.

i

l

!-

.

' .

2

The inspectors reviewed the onsite electrical distribution system to verify proper electrical

lineup of the emergency core cooling pumps and valves, the emergency diesel generators,

i

radiation monitors, and various engineered safety feature equipment. The inspectors also

verified valve lineups, position of locked manual valves, power supplies, and flow paths for

l

the high pressure safety injection system, the low pressure safety injection system, the

containment air recirculation system, the service water system, and the emergency diesel

j

generators. The inspector observed no deficient conditions.

l

Log-Keeping and Turnovers

!

.

The inspectors reviewed control room logs, night order logs, plant incident report logs, and

j

!

crew turnover sheets. No discrepancies or unsatisfactory conditions were noted. The

l

inspectors observed crew shift turnovers and determined they were satisfactory, with the shift

supervisor controlling the turnover. All members of the crew discussed plant conditions and

evolutions in progress. The information exchanged was accurate. The inspectors also

reviewed control room trouble reports for age, planned action, and operator awareness for

the reason for the trouble report. Most trouble reports reviewed were recent, with few

longstanding items.

At daily planning meetings, the inspector noted discussion on maintenance and surveillance

activities in progress and planned work authorizations. The inspectors conducted periodic

plant tours in the primary auxiliary building, turbine building, and intake structures. Plant

housekeeping was satisfactory.

2.2

Radiological Controls

During routine inspections of the accessible plant areas, the inspectors observed the imple-

mentation of selected portions of the licensee's radiological controls program. The inspector

reviewed utilization and compliance with radiation work permits (RWPs) to ensure that

detailed descriptions of radiological conditions were provided and that personnel adhered to

RWP requirements. The inspectors observed control of access to various radiologically

controlled areas and the use of personnel monitors and frisking methods upon exit from those

areas. The inspector noted posting and control of radiation areas, contaminated areas and hot

spots, and labelling and control of containers holding radioactive materials were in accor-

dance with licensee procedures. The inspector determined that health physics technician

control and monitoring of these activities were good.

2.3

Plant Operations Outside the Control Room

NRC inspection report 50-213/92-80 reviewed the CYAPCo program to meet Appendix R

fire protection requirements. The report expressed a concern that the 10CFR50 Appendix R

operator training program is based not on entire procedures, but rather on specific job

performance measures (JPM's). The JPM's are critical tasks within the procedure. The

NRC's concern was that this form of training does not train operators on an integrated

.

\\

.

.

i

.

response to a particular scenario. CYAPCo responded to this concern by revising the

operator requalification training program to train on the entire abnormal operating procedure

(AOP).

On March 5, the inspector observed operator requalification on AOP 3.2-50, " Plant Opera-

i

tions Outside the Control Room." The training simulated operator actions taken in the event

the control room is uninhabitable due to a fire. Three operators are designated to accomplish

actions within AOP 3.2-50, since the remaining portion of the crew is involved with the fire

,

brigade to combat the fire. The inspector observed appropriate use of radio communication,

adherence to the procedure, and operator awareness of essential equipment within the

" Operations Outside the Control Room" locker. The post-training critique was frank and

open in discussing the potential procedural deficiencies, and areas for improvement in

l

communications and coordination of the operations team. The inspector determined that the

training accomplished the objective to have a coordinated operator response to a particular

simulated fire scenario.

2.4

Engineered Safety Features System Walkdown

The objective of the inspection was to evaluate licensee control of the service water system.

The inspector evaluated maintenance and surveillance programs and practices for the service

l

water system. The inspector also completed a plant walkdown, reviewed applicable plant

information reports, and assessed the adequacy of engineering support for the system.

Surveillance and Maintenance

The inspector reviewed service water system surveillance procedures to verify that technical

specification (TS) surveillance requirements were met. The inspector used the control room

'

and auxiliary operator logs during a plant walkdown to verify that system parameters met the

'

conditions and values specified in the logs. The inspector also reviewed the calibration of

service water instrumentation, and the outstanding trouble reports and corrective maintenance

requests for the system. The inspector verified that the last completed surveillances were

within the interval for TS surveillance requirements 4.7.3.a.,4.7.3.b.l., and 4.7.3.b.2.

TS 4.7.3.a requires that the licensee verify that manual, power-operated, or automatic valves

servicing safety-related equipment are in the correct position. This must be done once per

month for valves that are not locked or otherwise secured in position. Based on review of

applicable drawings and licensee procedure SUR 5.1-152, " Service Water System Align-

ment," the inspector noted that all major flowpath valves servicing safety-related equipment

are not periodically verified. The licensee stated that his method for meeting the TS was as

described in Section 9.2.1.5 of the Updated Safety Analysis Report (UFSAR), which states

that the service water design basis assumes specific valve positions for a number of valves in

the safety-related portion of the system. UFSAR table 9.2-3 provides a list of valves subject

to periodic verification to meet the TS 4.7.3.a requirement. The inspector verified that SUR

5.1-152 agreed with UFSAR table 9.2-3. CYAPCo's stated that verifying the correct

i

.

<.

.

4

positioning of the valves listed in the UFSAR was sufficient to assure the service water

system design basis analyses remained valid. CYAPCo stated that valve positions not

checked were controlled by normal operating procedures. Further, operator actions each

l

shift to balance heat exchanger flows provided a functional verification of proper valve

positioning. The inspector concluded that this was acceptable.

,

The inspector reviewed shift log entries recorded by the auxiliary and control room opera-

tors. Maintaining the logs satisfies two TS surveillances: monitoring the flowrate for the

,

service water effluent radiation monitor; and, recording the number of operating service

'

water pumps for use in calculating flow rates for discharge permits. Routine log entries also

verify service water system operability based on requirements beyond those identified in the

TS, such as: service water design temperature (90 degrees Fahrenheit (F)); service water

flow rates to component cooling water heat exchangers; acceptable Adams filter operation;

and, the minimum Connecticut River level needed for service water pump operation.

The inspector reviewed outstanding trouble reports (TRs) and corrective maintenance

requests to determine whether service water system operability was jeopardized due to the

discrepant conditions. Eight TRs and twenty-two corrective maintenance requests were

outstanding on March 16. The oldest TR was approximately one and one half years old.

None of the conditions documented in the TRs jeopardized system operability. The discrep-

ancies included a misaligned spring can, corroded non-safety grade anchor supports, check

valve seat leakage, and a misaligned pin for the pump discharge strainer cover. The licensee

plans to work a majority of the corrective maintenance requests during the next refueling

outage. The planned maintenance includes valve inspections, repairing seat leak-by and

packing leaks, and repairing a motor-operated valve for the residual heat removal heat

exchanger.

l

The inspector verified that the licensee performed periodic calibration of selected instrumen-

tation within the system, and that results were satisfactory. The instrumentation selected for

this verification included those used for control room annunciators, and in normal operating

procedures, and abnormal operating procedures. The review included nine instruments that

monitor the following: containment air recirculation outlet temperatures and flowrate, service

water discharge header pressure, auxiliary building service water header pressure, service

water flow to the residual heat removal heat exchangers, and service water pump flow. The

inspector verified the instruments were periodically calibrated with satisfactory results.

1

System Walkdown

The inspector walked down accessible areas of the service water system. During the

walkdown, the inspector verified the accuracy of plant drawings against in-plant equipment,

,

l

and noted the condition of valves, instrumentation, and support systems. The inspector

(

verified system parameters using auxiliary and control room operator logs, and the installa-

'

tion of temporary modifications.

Various valve label tags were missing. The inspector notified the licensee of the location and

valve number of each discrepancy. The inspector reviewed administrative control procedure

(ACP) 1.0-57, " Plant Labeling Procedure," to evaluate the licensee's program. The program

provides a mechanism for workers to identify labeling deficiencies. The operations depart-

ment is responsible for administration of the program. CYAPCo was in the process of

correcting the valve label deficiencies at the end of the inspection period.

The inspector also noted poor equipment condition on the service water header "Annubar"

.

flow instrument lines (FE-433, 435, 437, and 439). The instrument lines were bent and

poorly supported. The licensee was informed by the inspector of this condition, and plans to

!

address the deficiencies.

!

!

The inspector did not identify any drawing errors. System parameters were within the

expected range, and good housekeeping was noted around service water components and

support systems.

-

l

Plant Information Reports

The inspector reviewed licensee root cause determinations and corrective actions associated

!

with 1992 plant information reports (PIRs) concerning the service water system. Approxi-

mately eight percent of all PIR's issued were related to the service water system. The causes

of the problems documented in the PIRs included design discrepancies, the failure to update

operating curves following a modification, check valve internal wear, fouling of service

l

water components, and improper clearance of equipment tags. Corrective actions for these

events included implementing plant design changes, revising operating curves, and revising

administrative control procedures. Two of the events were documented in licensee event

reports (LERs)92-012 and 92-015. The inspector concluded the corrective actions were

acceptable.

Engineering Support

To assess engineering support for the service water system, the inspector reviewed: the

t

safety evaluation determinations for AOP 3.2-19, " Loss of All Service Water"; the technical

evaluations for installed temporary modifications; and, the technical basis for the lack of

service water header independence.

To validate the adequacy of safety evaluation determinations, the inspector considered 10

!

CFR 50.59, ACP 1.2-6.12, " Safety Evaluations for Station Procedures," ACP 1.2-6.9,

" Safety Evaluations - NEO 3.12," and past revisions to AOP 3.2-19. CYAPCo initiated

written safety evaluations for revisions two and seven of AOP 3.2-19. The basis for the

l

safety evaluation determinations was consistent with ACP 1.2-6.12 and ACP 1.2-6.9. The

i

inspector concluded that the licensee had an acceptable basis for not developing a full written

!

safety evaluation per ACP 1.2-6.12 for the remaining AOP revisions. The inspector

determined the technical evaluations for the four installed temporary modifications provided a

l

_

_ _ _ _

.

..

.

i

.

sufficient description of the change. Also, the safety evaluation conclusions for the tempo-

rary modification were appmpriate.

-

l

The inspector noted that the normal configuration for the service water system is to maintain

I

the header cross-connect valve SW-V-102 open, which does not provide for header indepen-

dence. This matter was discussed with CYAPCo engineering personnel. The licensee's

basis for not maintaining header independence was: no separation is provided to the service

water supply to the containment air recirculation fans; the design does not maintain electrical

independence for safety-related motor-operated valves; and, the probability of a pipe rupture

I

is low. Additionally, a complete loss of service water does not result in a potential core

melt scenarin, The system design approved by the NRC staff as described in Section 9.2 of

the UFSAR does not require independent service water headers. The TS bases state that the

'

service water headers may be tied together by an open service water cross-connect in the

intake structure. The inspector concluded that operation of the service water system without

>

header independence is in accordance with the licensing basis, and is appropriate based on a

consideration of the risk to plant safety.

'

Conclusion

.

The inspector concluded the licensee appropriately maintained the operable status of the

!

service water system. Maintenance and surveillance activities were acceptable to maintain

system operability. Minor housekeeping issues existed concerning plant labeling and

1

instrument line support. The inspector also determined engineering support was good to

.

'

provide an acceptable system design and to assure the safety function was maintained.

2.5

Licensee Actions During Blizzard Joshua

l

The inspector reviewed licensee actions during the period fmm March 12 -13 as Storm

Joshua moved into Southern New England. Licensee plans and actions to assure adequate

shift staffing and the supply of consumables necessary for safe plant operation were also

reviewed. This major snow storm was projected to have 60 mile-per-hour wind speeds at

Haddam Neck. An Unusual Event emergency classification would be declared for sustained

wind speeds in excess of 75 mph.

The licensee's preparations for the storm included around-the-clock staffing by building -

_

services personnel who ' worked on snow removal for the site and the plant access road. The

site area was canvassed to secure loose equipment and debris. Additional personnel

necessary to provide relief for security, operations, chemistry and health physics crews were--

called in to the site in advance of the arrival of the storm. Additional craft personnel were

. also called in to assure contingency staffing of the emergency organization. Meal and

.

sleeping accommodations were provided for site workers during rest periods. A management

representative was on site throughout the period in the position of the onsite director of site

'

- emergency operations (DSEO).

The inspector monitored weather and road conditions and plant actions during the period

from March 12 - 15 as Storm Joshua moved through Southern New England. Inspector

reviews during this period focused on the weather conditions experienced at the plant, the

status and implementation of contingency plans and whether any problems were encountered

,

i

meeting the contingencies. The eye of the storm passed through the site area at 3 a.m. on

March 14. Maximum sustained wind speeds reached about 40 mph. Access roads to the

station remained passable during the storm. As area conditions worsened during the evening

of March 13, site management elected to hold the normal midnight to 8 a.m. crew offsite and

to provide shift coverage with the augmented onsite staff. Normal shift staffing resumed

during the subsequent shifts on March 14. The plant remained operating at full power

l

throughout the period. Both offsite power and onsite emergency supplies remained available.

No operational problems were encountered,

j

No inadequacies were identified in the licensee's response to Storm Joshua. The inspector

l

concluded the licensee contingency planning and actions were timely, prudent and effective to

!

assure both plant and personnel safety.

2.6

Manual Reactor Trip

'

Event Description

On March 23, at approximately 8:44 a.m., with the unit at full power and while establishing

conditions to perform a flux map, the control room operators observed rod cluster control

l

assemblies (RCCAs) 31 and 32 partially insert into the reactor core by approximately 45

steps. RCCA 31 and 32 are in control Bank B (group 8), and are located at the periphery of

'

the core. At approximately 9:15 a.m., the licensee initiated actions required by the technical

specifications to align the Bank B RCCA's. During the alignment, RCCA 31 and 32 again

inadvertently inserted into the core by an additional 100 steps. Based on the improper

control rod operation, the operators initiated a manual reactor trip. All safety systems

responded as designed after the reactor trip. However, the high pressure steam dump

(HPSD) control system malfunctioned, resulting in a small unexpected plant cooldown. The

secondary reactor operator took prompt action to isolate the HPSD system and stop plant

cooldown. At 9:55 a.m., CYAPCo informed the NRC Operations Center pursuant to 10 CFR 50.72(b)(2)(ii) of a condition resulting in a manual actuation of the reactor protection

'

system.

Operator Response

The inspector was in the control room at approximately 9:00 a.m. At that time, the control

room operators were performing actions within AOP 3.2-23, " Malfunction of the Rod

Control System," and annunciator procedure (ANN) 4.20-20, "NIs PR Channel Deviation."

The specific actions were to place the rod disconnect switch in disconnect for RCCA's 31

and 32, and to adjust the nuclear instrument gains. The operators also appropriately entered

into TS action statement 3.1.3.c.1, which requires the operator to either align all RCCAs

.

-.

c

.

.

.

within the bank to within 24 steps within one hour, or be in a HOT STANDBY condition

within six hours. At 9:15 a.m., the primary operator began to align the unaffected Bank B

RCCA's to within 24 steps of rods 31 and 32. As soon as the operator initiated rod motion,

RCCA 31 and 32 inserted an additional 100 steps into the core.

The senior control operator (SCO) immediately recommended to the shift supervisor that the

reactor be tripped. The shift supervisor acknowledged the recommendation, and ordered a

j

reactor trip. Non-involved personnel either left the control room, or did not distract the

control room operators as they implemented the emergency operating procedures. The

j

communication between the SCO and the reactor operators (ROs) was precise, and very well

l

controlled. The inspector observed excellent implementation of procedures E-0, " Reactor

Trip or Safety Injection," and ES-O.1, " Reactor Trip Response." All RCCA's fully inserted

into the core, and safety systems functioned as required.

The inspector observed very good actions by the secondary plant RO following the trip. The

RO quickly recognized from board indications that an abnormal cooldown was in progress.

l

Specifically, pressurizer pressure and level were low at 1820 psig and 25%, respectively,

j

and, reactor coolant system average temperature was below the expected post-trip value of

535 degrees F. The RO recognized that no main steam or pressurizer code safeties had

lifted, and that the HPSD was controlling reactor coolant system Tave. The operator isolated

the HPSD by shutting motor-operated valves MS-MOV-520 and MS-MOV-553. The

l

cooldown stopped at a RCS Tave of 525 degrees F, and with pressurizer pressure at 1780

psig, and pressurizer level of 17%. The secondary RO's prompt actions stabilized the plant

and avoided the potential complications of a safety injection (pressurizer pressure at 1700

psig) in this case. The plant was stabilized at normal post-trip conditions.

j

Corrective Actions

CYAPCo work planners, the outage coordinator, and representatives from each department

j

met at 10:30 a.m. to discuss the scope of necessary work activities, and the duration of the

forced outage. The inspector observed good discussions by the group to identify the

cerrective maintenance, preventative maintenance, and surveillances that should be done

l

during the outage, beyond that needed to identify the cause for the HPSD and the rod control

system malfunctions.

,

The licensee identified on March 23 that the cause the RCCA insertion was a loose mechani-

l

cal arm on the contactor in the power supply to the stationary coils. The details regarding

j

this failure and the licensee's corrective actions are documented in Section 3.1 of this report.

No specific cause was identified for the HPSD control system malfunction. Shortly after the

'

trip operators identified that steam dump temperature control valve TCV-417-B4 was

partially open. However, troubleshooting and calibration of this temperature control valve

and the seven other valves did not identify a circuit malfunction. The valves were stroke

tested and subsequently operated properly.

The Plant Operations Review Committee (PORC) reviewed the post-trip documentation, root

cause determinations, operator actions, and plant response. Engineering personnel confirmed

that the plant responded as expected. The PORC recommended re-start of the unit based on

identification of the cause of the rod control problem, and will continue to evaluate the

HPSD malfunction by keeping the issue open in a control routing.

The inspector compared the plant response with two partially inserted RCCA's to the

dropped rod analysis described in Section 15.2.6 of the Updated Final Safety Analysis Report

(UFSAR). The review was performed to determine whether the unit response was bounded

by the assumptions in the UFSAR analysis. The analysis assumes only one RCCA fully

inserts into the reactor core, whereas on March 23 two RCCA's partially inserted into the

core. The plant conditions and response were bounded by the seven assumptions in UFSAR

section 15.2.6. No unsafe condition existed, nor were there any challenges to the safety

limits. The inspector did note that AOP 3.2-23 requires the operator to manually trip the

reactor if more than one RCCA fully inserts into the core. The principal reason for this

requirement is to ensure that plant conditions remain bounded by the UFSAR analysis.

Conclusions

The inspector observed the event from the control room and noted that the communication

between control room operators was precise, and well controlled while implementing the

emergency operating procedures. The root cause of the rod control system malfunction was

appropriately identified prior to a plant restart. The plant responded as expected to the

dropped RCCAs, and safety limits were not challenged.

2.7

Strike Contingency Plan

Plant workers are represented by the International Brotherhood of Electrical Workers (IBEW)

Union, Local 457. The three year union contract expired on March 1,1993. Plant workers

continued to work without a contract as negotiations continued. The inspector reviewed the

licensee's plans and actions for responding to a work stoppage in the event of a job action.

j

Licensee planning was formalized six weeks before the expiration date.

The inspector focused on the licensee's plans to meet the minimum shift staffing require-

ments specified in Technical Specification 6.2.2 for operators, fire brigade members, and for

personnel experienced in radiation protection procedures. The inspector also reviewed the

licensee's staffing plan to assure continued performance of surveillance and testing activities

as required by the technical specifications.

The inspector determined that the licensee could staff three operating shifts with exempt

personnel who possessed either senior reactor operator (SRO) licenses or operator licenses,

as required. The licensee also identified those licensed personnel who would first have to

stand watch for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> to activate their licenses. These personnel would stand watch in a

training status under the supervision of the operating shift prior to crediting use of their

l'

.

.

I

l

10

,

licenses to meet the minimum staffing requirements for the watch bill. The shifts would be

l

staffed with members of the training department or former operators who had plant specific

knowledge. The licensee also planned to use at least one supervisory control room operator

(with an SRO license) on each shift in auxiliary operator position. This was a good licensee

initiative to assure that in-plant activities would be directed by a supervisor having good

,

familiarity with present plant operating conditions.

.

t

To meet fire protection program requirements, the licensee planned to use a four-person

complement of security shift supervisors, who were fully qualified fire brigade members at

<

l

Haddam Neck. The four-person guard contingent together with the duty SCO would staff the

required five-person fire brigade. This brigade would be implemented immediately to staff

the first shift. Arrangements were also made to bring 12 fully qualified fire brigade

personnel from Millstone to the Haddam site during the first shift of contingency staffing.

After completing a 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> training session on CY site specific fire protection features, these

personnel would be available to join the three operating shifts. The licensee had further

,

j

plans to qualify additional personnel for fire brigade duty.

l

l

No inadequacies were identified regarding the licensee's plans to staff the operating shift with

i

l

operations, maintenance and I&C personnel. The licensee plans assured an adequate number

l

of workers on each shift to safely operate the plant and to meet license conditions. The

licensee's contingency plans also assured adequate numbers of personnel were available to

j

implement the emergency plan. A new three year contract was accepted by the union on

'

March 12,1993. The inspector identified no inadequacies in the licensee's contingency

!

plans.

2.8

Plant Startup

The inspector observed control room activities on March 24 to restart the plant in accordance

with procedure NOP 2.1-2, " Reactor Startup " The review was conducted to assure, by

direct observation, that the plant was ready to be restarted in accordance with the technical

specification requirements, and that the approach to criticality was conducted in accordance

with licensee administrative controls. The following observations were made:

Shift staffing met requirements and activities within the control room were well

e

controlled by the shift supervisor. Only personnel directly involved with the restart

were present. Management personnel monitored the restart.

Plant staff provided timely support to the operators as needed to address operational

needs. This included actions by I & C personnel to adjust control rod position

indication. Reactor engineering provided good assistance to complete inverse

multiplication plots during the approach to criticality and by providing prompt updates

to the estimated critical rod position during a period of rapid change in xenon

reactivity worth.

during the restart: - TS 3.1.3 - shutdown margin and control rod position; TS 3.1.1 -

l

moderate temperature; TS 3.4.1 - reactor coolant system and pressurizer operation;

and, TS 3.8 operable normal and emergency power systems.

l

I

j

The primary plant reactor operator declared the reactor critical at 3:08 p.m. with cor. trol rod

bank 'B' at 70 steps withdrawn. This agreed favorably with the estimated critical position of

97 steps on bank 'B'. The approach to critical was completed in a safe and orderly manner.

The shift supervisor and the supervisory contml room operator maintained good control over

plant staff and operator activities. The main generator was phased to the grid at 7:45 p.m.

l

The unit returned to full rated power on March 25 at approximately 6:45 a.m. No inadequa -

l

cies were identified by the inspector during the startup. ,

l

2.9

Plant Downpower Due to Noise in 'B' Main Feed Pump

l

On March 15 at 11:10 a.m., CYAPCo commenced a plant load decrease after operators

noted noise from the 'B' main feed pump motor. Plant power was reduced to 60% of rated

to shutdown and inspect the feed pump motor. CYAPCo identified a piece of shroud gasket

material lodged in the feed pump motor air vents. Although most of the gasket material had

.

been removed prior to initial motor operation at the facility as recommended by the vendor,

a small piece had remained undetected until it became loose on March 15.

.

Licensee mechanics removed the gasket material and engineering personnel inspected the

motor for damage. No motor damage occurred and the pump was restarted satisfactorily.

CYAPCo returned the pump to service and the plant reached full rated power on March 17.

,

2.10 Entry into Technical Specification Limiting Conditlom for Operation During

-

Performance of Surveillances

NRC Generic Letter 91-18, "Information to Licensees Regarding Two NRC Inspection

Manual Sections on Resolution of Degraded and Nonconforming Conditions and Operabili-

ty," was issued to ensure consistency in the application of operability guidance by NRC

personnel. No specific action was required by the licensee in response to the generic letter.

Inspector review of the guidance determined that if the technical specifications (TS) required

that safety equipment be removed from service and rendered incapable of performing its -

intended function, the equipment is inoperable and the limiting conditions for operation

(LCO) must be entered unless the TS explicitly directs otherwise. The inspector noted that

CYAPCo actions do not always conform with the NRC guidance. Specifically, the licensee

does not consistently enter TS LCO's during the performance of operability surveillances that

render the equipment inoperable. An example of this practice was on March 16,1993 when

the shift supervisor logged completion of TS surveillance SUR 5.1-13B, " Auxiliary Feed

Pump P-32-1B Functional Test," at 10:10 a.m. The system was rendered incapable of

The licensee historically has recorded the performance of surveillances in the station log and -

has noted the completion time of the test. CYAPCo credits TS LCO references within the

i

surveillance as a measure to ensure operator awareness of TS applicability and allowed

'

outage times. Further, CYAPCo stated that periodic Plant Operations Review Committee

'

i

i

(PORC) review of surveillance procedures assures that the test can be completed safely and

i

in accordance with the TS allowed outage times. ' Routine resident inspection has not

1

identified a condition where performance of a TS surveillance has exceeded the allowed

j

outage time.

I

This general topic was discussed on March 23,1993 during a meeting between the licensee

and the NRC staff. In accordance with the guidance in Generic letter 91-18, the NRC staff

i

will allow the licensee time to review its practices and to make improvements to its proce-

l

t

dures and technical specifications, as needed, to assure that adherence to the guidance will

,

not cause undue disruption to stable plant operation. The licensee agreed to improve

i

operator sensitivity to this issue. The licensee further agreed to inform the staff how plant

procedures will be revised to assure better conformance with the guidance in the future. The

>

!

schedule for this effort is under development. Additionally, the licensee intends to partici-

'

pate in the industry initiative to address the intent of the NRC's guidance. -The inspector had

no further questions regarding this matter at this time. Licensee actions to meet technical

' specification LCOs during surveillance testing is routinely reviewed during resident inspec-

CY 93-3264, Control Rod 31 & 32 Contactor Replacement

l

The inspector reviewed licensee actions under CY 93-3264 to investigate and repair a

l

malfunction in the rod control system on March 23. While establishing conditions to

perform a flux map, the operator manually inserted control bank 'B' at 8:45 a.m. This

action resulted in the partial insertion of group 6 rods 31 and 32, causing them to be 45 steps

below the remaining 6 rods in bank 'B'.

After preparing to realign the rods with the bank,

!

the operator attempted to manually insert rods at 9:15 a.m. This action resulted in further

insertion of rods 31 and 32 by another 100 steps. The operator immediately scrammed the

reactor after the second uncontrolled rod motion.

l

Licensee inspection of the rod control system components identified a faulty contactor that

I

was in series with the common power supply to the stationary coils of rods 31 and 32. The

contactor is a Westinghouse Type MM 310, Style 1502677 direct current, single pole,

magnetic contactor. Specifically, two fasteners were loose which allowed the moveable

portion of the main contact to become misaligned with the stationary contact and thereby

interrupt the 125 Vdc power supply to the stationary coils (reference drawing 16103-32121

sheet 16, " Control Rod Sequencing Circuitry VII"). The fasteners were loose in spite of the

,

l

presence of lock washers provided to assure the connection remained secure. The fasteners

were re-tightened after replacing the lock washers as a precautionary measure. Additionally,

i

the licensee inspected the remaining contactors used for other coils (stationary, moveable and

,

lift) in the rod control system to assure they were tight. No other loose fasteners were

found. Finally, the licensee intends to add a requirement'to the procedure PMP9.5-2, " Rod

j

i

Control System Preventive Maintenance," to check the fasteners once per operating cycle.

Inspection of this area also included a review of rod control system electrical drawings,

discussions with maintenance personnel, and a review of the components in the rod control

cabinets in the 'A' switchgear room. The inspector verified the licensee's root cause

determination for the control rod malfunction. The failure of the stationary coil contactor to

close as required would allow the control rod to free fall into the reactor until the moveable

coil is energized in the next step of the sequence to move (insert or withdraw) a control rod.

The inspector also reviewed the preventive maintenance performed on the rod control system

per PMP 9.5-2. This review considered the number of components in the rod control

system; the number of checks included in the PM procedure; the recommendations for PM

described in Westinghouse Instruction I.L.10245A for Type MM Contactors; and, the

failure history of control rods and contactors at Haddam Neck, and in the industry.

Although control rod failures have occurred in the past, none were attributable to loose

fasteners. The stationary coil contactor for rods 31 and 32 has not been replaced recently,

and is most likely original equipment for the plant. Based on this review, the inspector

concluded the PMP 9.5-2 was reasonably complete in view of the complexity of the rod

-

,

!

.

.

.

.

14

control system. Further, the control rod malfunction on March 23 would not have reason-

ably been prevented. The proposed revision to PMP 9.52 to include a check of the fasteners

4

is a good enhancement to the PM program.

'

The inspector concluded the licensee actions to investigate and repair the rod control system

malfunction were thorough. No inadequacies were identified.

CY 93-3308, Reactor Trip Breaker Closing

The inspector reviewed licensee actions under CY 93-3308 to investigate the 'B' reactor trip

breaker. The breaker would not close reliably during the conduct of routine surveillance

testing on March 24 with the reactor shutdown in operational Mode 3. The licensee

identified the need to adjust the actuating arm for an interlock that prevented latching the

4

main breaker coil in the "after-trip" position. The inspector interviewed maintenance

,

personnel and reviewed the operation of the breaker to verify that the problem could not

prevent the breaker from opening in response to a manual or automatic trip signal. The

inspector noted that the maintenance personnel were very knowledgeable of the breaker and

its operation. No inadequacies were identified regarding the licensee's corrective actions.

'

3.2

Individual Rod Position Indication

On March 7, CYAPCo identified that the individual rod position indication (RPI) for RCCA

30 deviated from the average RPI for the group, and deviated from the group position

4

indication system (group step counters). The position deviation exceeded the TS 3.1.3.2

'

requirement. Spurious RPI deviations occurred six times between March 7 and March 9.

The control room operators entered action statement 3.1.3.2.a. during each occurrence. The

operators either logged out of the TS when the control room annunciator cleared (the RPI

returned to within the allowed band), or requested I&C specialists to perform a rod calibra-

tion pursuant to CMP 8.2-70, " Rod Position Indication System Adjustments at Power." On

March 10, CYAPCo initiated a plant downpower to less than 90% rated to perform trouble-

shooting on control rod 30 circuitry. PIR 93-032 was written to document this issue. The

power reduction was performed as a precaution since the proposed troubleshooting would

remove the main turbine runback feature on a rod drop for five of the RCCA's. The turbine

runback feature is not applicable at less than 90% power. The troubleshooting did not

identify a cause for the periodic RPI deviation.

CYAPCo swapped the signal conditioner drawers for rods 30 and 31 as troubleshooting

'

activities continued on March 16. The inspector verified that the appropriate TS action

statement and troubleshooting precautions were adhered to. By swapping the conditioner

drawers, CYAPCo identified that capacitors and the span adjustment potentiometer had

degraded in the drawer for rod 30. The licensee repaired the components and restored the

rod 30 to an operable status.

l

NRC inspection report 50-213/88-08 documented deviations between individual RPI and the

average of GPI was a chronic problem. CYAPCo concluded, based on the operating

experiences, that temperature changes in containment, and the control room cause deviations

in the output of the linear variable differential transformers (LVDTs) from which the RPI is

derived. Additionally, secondary output signals are not linear during the course of full rod

motion. The plant process computer is used to adjust the LVDT output signal to reflect

I

expected motion of individual RPI. The correction factors used by the computer were

derived from test data.

The licensee has rebuilt the rod control system signal conditioning circuitry, developed

computer =cdeling to track expected rod position, maintained operator sensitivity, and

i

developed appropriate operability determinations as required. Future actions under consider-

ation to improve individual RPI performance include: an engineering evaluation by project

services engineering under project assignment 89-054; and, the development of a special test

,

l

by reactor engineering to quantify and characterize temperature effects on the LVDT and

j

signal conditioning circuitry. The inspector had no further questions regarding licensee

l

planned actions at this time.

In summary, the inspector identified no inadequacies in licensee activities to address RPI

deviations during this period. Corrective actions were thorough to address faulty components

l

in the signal conditioning drawer for rod 30. The licensee has taken significant actions in the

l

past to address RPI problems, and plans to address this problem further through special

testing are a good initiative.

ENGINEERING AND TECIINICAL SUPPORT (71707)

4.1

Loose Parts Monitoring System

The loose parts monitoring (LPM) system continuously monitors reactor vibration using

accelerometers on the reactor vessel. The monitored locations ace designed to detect metal-

like impacts in the reactor as they occur. The system is not listed in the technical specifica-

tions, nor is it described in the UFSAR as a required plant feature. The system was installed

as a licensee initiative in 1987 under plant design change (PDCR) 921, "Imose Parts Monitor

Installation." The LPM was installed following repairs to the reactor internals with the

primary purpose of monitoring performance of the thermal shield during subsequent plant

operations. However, the reactor thermal shield was permanently removed during a

subsequent plant outage. The licensee initially intended that the system design and installa-

tion nieet the requitements of NRC Regulatory Guide 1,133; the systen1 requirements were

subsequently changed to ASME OM 12.

The inspection included a review of the controls for, and the past performance of the LPM

l

system. The inspector reviewed plant information reports (PIRs) and LPM procedures, and

walked down portions of the system. There have been four PIRs issued against the LPM

l

t

. .

e

'

16

system since 1989. The PIRs described problems with rebooting the software after an alarm,

4

damage to the system due to lightening, and, response to " impact-events."

NUSCo Component Test Services (CTS) provides significant support for the system during

routine system operations and testing. ACP 1.0-58, " Loose Parts Monitoring System,"

provides the CYAPCo controls for use of the system. No specific procedure exists at

Haddam Neck to perform functional tests of the LPM system.

NUSCo CTS provided assistance to CYAPCo in start-up and testing of the LPM system in

February,1992, following the refueling outage. The testing demonstrated that 4 out of 6

accelerometers could detect and record mechanical impacts. Two sensors (#4 and #5) are

considered inoperable by CYAPCo due to unresolved cable penetration deficiencies. The

most recent ' impact-like' event (January 21, 1992) was evaluated by CTS. The event was

registered at channel #3 (upper reactor vessel head). The NUSCo evaluation concluded that

the ' impact' was mechanical noise associated with routine control rod movements.

As part of PDCR 921, CYAPCo intended to update the UFSAR, and to provide on-going

technical training to plant personnel on the LPM system. As of this inspection period, the

LPM system is not described in the UFSAR. The last technical training provided on the

system was in June,1991. No on-going training has been provided to instrumentation and

control (I&C) specialists. When questioned regarding the system status, licensee engineering

acknowledged that the PDCR package was still open and its completion had been given a low

priority.

Conclusion

The inspector noted the LPM system at Haddam Neck is operational and is used to monitor

reactor conditions. NUSCo CTS personnel support calibration, testing and maintenance of

the system. No formal procedure exists to document reproducible calibrations. The PDCR

installing the system is still open and action to update the UFSAR and to train site staff are

'

incomplete. Although there are no regulatory requirements or commitments regarding use of

_

the system, the inspector determined that the licensee could improve the calibration proce-

dures for the LPM, as well as the training provided to instrumenta' ion specialists.

4.2

Service Leak Water

On March 8, CYAPCo identified two pinhole leaks in the six inch service water supply to

the 'B' emergency diesel generator (EG-2B). Leakage points were located at a butt weld

joint approximately ninety degrees apart. CYAPCo identified the leaks while preparing the

surface for ultrasonic wall measurements pursuant to work request CY-92-12463.

CYAPCo initiated non-conformance report 93-016, PIR 93-027, and actions prescribed in

NRC Generic Letter 90-05, " Guidance For Preforming Temporary Non-code Repair of

ASME Code Class 1,2, and 3 Piping." CYAPCo immediately characterized the flaw, and

.

i

measured the leakage at approximately fifteen drops per minute. NUSCo engineering

j

supported CYAPCo engineering by providing an operability assessment. The assessment

'

concluded that the structural integrity of the piping was acceptable, since: the pin holes were

less than 1/32 of an inch; ultrasonic test results concluded the wall thickness was within

]

87.5% of nominal wall, and estimated wall loss until the refueling outage (starting May 15)

is not expected to reach minimum wall. The inspector noted that isolation of the service

j

water leak would require isolation of one of the two service water headers, resulting in

!

entrance into a 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> action statement.

and reviewed administrative control procedure (ACP) 1.0-78, " Outage Planning, Scheduling,

and Implementation." The review focused on CYAPCo shutdown risk initiatives, plant

modifications and the work order deferral processes.

Results

In November,1992 CYAPCo prepared the first administrative procedure to outline methods

for preparation and conduct of scheduled outage. The inspector noted that various terms and

job responsibilities that existed in past outages were now proceduralized. One major change

to the method of outage planning is the ongoing work of shutdown risk management by .

- CYAPCo. At the end of the inspection period, an outage schedule safety num< ment team

was formed. The team consisted of the engineering manager, Instrument & Controls .

Manager, representative from the operations department, the maintenance electrical supervi-

sor, and a NUSCo individual knowledgeable in probabilistic risk assessment.' A major task

of the group was to evaluate all systems out of service (SOS) work activities to verify that

safety function requirements (of ACP 1.0-78, Attachment 12.1) were maintained. The safety

function requirements are for decay heat removal, electrical power availability, reactivity

control, reactor coolant inventory, and containment control. ACP.I.0-78 also details a

process to evaluate emergent work activities during the outage. Each of the emergent .

activities will be evaluated to ensure the safety function requirements are preserved; this

safety assessment will have concurrence from the outage manager.

During the inspection period, the outage manager position was permanently filled by an

experienced senior reactor operator with previous experience in daily planning activities.

The outage manager is a new full-time position within CYAPCo's organization.

On March 25, the inspector observed a monthly outage planning meeting. During the

meeting, the licensee listed the status of action items to resolve prior to the outage. The

licensee also solicited any comments or issues yet to be resolved. Examples of action items

discussed were working hours, impact of changes to administrative control procedures on

retest requirements and station tagging, status of engineering project assignments, and -

various safety equipment outage schedules. Each action item was assigned a responsible

individual for resolution, and provided a commitment date for completion. - It was apparent

to the inspector that action items were over-due from the previously arranged completion

date. . In addition, it appeared that significant outage planning and scheduling milestones were

delayed. The meeting did provide a forum to discuss the delays, their reasons, and the

management expectation for completion of individual iten)s.

On March 10, the inspector observed a meeting to discuss engineering modifications planned

for the refueling outage. The meeting included all discipline organizations. The purpose of

the meeting was to evaluate modifications and determine which will be implemented,

deferred, or removed from consideration. Prior to the meeting, each of the eighty-six (86)

modifications was prioritized as "must do", "need to do", and "want _to do". The prioritiza-

tion was based on either NRC commitments, significant risk of a forced outage, correction of

_ _ _

j

'

.

.

19

plant equipment failure or deficiency that impacts plant operation, or improve the operability,

maintainability or design of plant equipment. Approximately twenty-five percent of the

modifications were deferred from implementation during the Cycle 17 refueling outage.

The inspector selected five modifications that had been deferred to understand the why the

change was initiated, the reasons for deferral, why plant safety is not impacted by the

,

deferral, and tracking of the deferral. The modifications specifically reviewed were plant

design change records (PDCRs) 1368, " Replacement In-Core Sump level Transmitter,"

i

1277, " Motor Operator Valve Overload Trip Indication Circuit Modification," and 1354,

" Containment Air Recirculation Fan Service Water Instrumentation," and replacement item

evaluations (RIES) CYOE 93-29 " Replacement of FW-CV-153/184," and CYOE 93-05,

" Loop Stop Valve Operator Replacement." The plant modifications were initiated for a

variety of reasons, including: consolidation of instrumentation; problems with transmitter

calibrations; replacement of a commercially-dedicated item with QA Category I item;

corrective actions proposed in response to a past NRC Information Notice and plant

information report (PIR); problems acquiring spare parts; and, on-going maintenance

,

'

corrective items. Generally, the reasons for deferral included removal of component safety

function due to another plant modification, acceptable component performance, procedural

changes, training awareness, or lack of importance of an instrument based on indication from

other safety-related instrumentation. The tracking of deferred modifications will be main-

tained by each respective system engineering supervisor. The deferred items may be

accomplished during non-outage operations, or scheduled for the next refueling outage.

The inspector concluded that CYAPCo provided reasonable justification to defer plant

modifications. For the specific modifications reviewed, deferral does not impact plant

safety, nor any previous NRC commitments. An appropriate level of oversight exists for the

final decision to perform or not perform the modification during the outage.

The inspector also reviewed CYAPCo's process to reschedule the performance of corrective

and preventive maintenance activities. Principally, licensee personnel determine if the

activity needs to be completed during an outage. Approximately 8 - 10% of previously

planned work activities will not be performed during the refueling cutage. For activities that

could be performed during power operation, CYAPCo has initiated a ' system of the month'

schedule to perform maintenance on systems during power operation. Recent examples

include work on the steam generator blowdown system, fire protection system, steam system

traps, and spent fuel pit heat exchangers. The inspector concluded that the system outages

during power operation were appropriately planned, and had no impact on safety-related

equipment or functions.

On March 15, the inspector reviewed seventeen work orders that have been deferred from

the outage. Based on the individual work scope and CYAPCo reasons, it was apparent that

appropriate justification existed for deferral.

Nuclear Review Board

..

The inspector observed the meeting of the Connecticut Yankee Nuclear Review Board (NRB)

on March 18. The inspector verified that requirements for a quorum,' discussion items, and-

the approval of the meeting minutes were all satisfied. The inspector noted good probing

i

discussions concerning a proposed technical specification amendment to remove fim

.

protection requirements from the technical specifications. The NRB approved the amend-

' j

ment request contingent upon maintaining the NRB audit role. Good discussion was noted

i

concerning the reporting of fire protection issues, as affected by revised. wording in the

i

license condition.

Three open items carried forward (ICF) were developed during the meeting. The items

concerned a programmatic review of valve operator environmental qualification issues as

'

.

l

described in NRC inspection report 50-213/92-22, verification of proper closure of the 1990

.1

Combined Utility Assessment Team audit findings, and issuance of a document informing the

Executive'Vice-President'- Nuclear of on-going welding practices and program deficiencies.

The deficiencies as highlighted in QSD audit 30201, " Field Welding Control."

t

The NRB chairperson announced to the board that effective May 1,1993, the Vice-President

Nuclear, Engineering Services will be the new board chairman. -The change is intended to

provide a higher level of management participation in the nuclear oversight group. The

current NRB chairperson will be assigned as vice-chairperson, and the current vice-chairper-

son will be assigned as a member.

Management Meeting

On March 17, 1993, from about 10:30 a.m. to 12:30 p.m., Messrs. John Opeka and

,

Richard Kacich of Northeast Utilities (NU) met with Mr. T. T. Martin, Regional Adminis-

'

trator, and five other NRC Region I managers at the NRC Region I office. The meeting was

held at NU's request to discuss the results of recent NU economic analyses related to

Haddam Neck. Although meetings between NRC and licensees are typically open for public

observation, NRC approved NU's request for a closed meeting, because the meeting

(1) included NU proprietary business information and (2) had no dimet substantive connec-

tion to any specific regulatory decision or action.

Attachment I provides the licensee's non-proprietary presentation materials. Attachment II is

the licensee's affidavit supporting their request for a closed meeting. At the meeting, the

licensee discussed the increasing influence of competitive forces and economic regulation on

the continued operation of nuclear units, briefed NRC management on preliminary results of

the economic analysis for Haddam Neck, and provided their views on associated regulatory

implications. No commitments were made by either NU or NRC, nor were any NRC

positions or decisions provided. In addition to Mr. Martin, NRC Region I attendees included

William Kane, M. Wayne Hodges, Susan Shankman, James Wiggins and Randolph Blough.

AFFIDAVIT

i

,

l

'

!

I, John F. Opeka, being duly sworn, depose and state as follows:

_

i

1.

I am currently the Executive Vice President with Connecticut. Yankee

!

Atomic Power Company (CYAPCO).

. I am filing this affidavit in -

support of NNECO's request that the meeting with members of the

. ,

!

j

Staff from Region 1 of the Nuclear Regulatory Commission ("NRC")

~

(Docket No. 50-213), scheduled for. March 17, 1993,.be closed to the

public.

-

i

2.

The purpose of the meeting with the -NRC' is ' to discuss CYAPCO's'

l

Economic Analysis for the Haddam Neck Plant.

3.

The Economic Analysis for the Haddam Neck Plant reflects CYAPCO's

!

. projections of costs and returns and the Company's budget estimates,.

i

as well: as other sensitive proprietary information related to the

operation of the power plant.

-

4.

The information contained in the Economic Analysis.is deemed to be

confidential proprietary business iinformation by CYAPC0.

This

!

information is customarily held in strict confidence by CYAPC0 and

is not, to the best of my knowledge and belief, 'available to the

public.

~

lu

5.

Disclosure of the information contained in the Economic Analysis

through the opening of_ the meeting with the NRC could have a severe

- i

detrimental financial impact on the. operationsjof CYAPCO. _ For

example, a member of the public or the press attending the meeting

.

would not have access to all the confidential proprietary business

_

records of CYAPC0; therefore, the observation of the discussion of

i

selected portions of these records could cause such an individual to

acquire an inaccurate' perception of ' the - financial condition of

CYAPC0 -- a perception that could be injurious'to the Company.

In

,

addition, allowing the public to be present for such discussions

could stifle the ability of CYAPCO to discuss fully the Economic

Analysis for fear of widely disseminating other related ' sensitive

financial data.

6.

The development of the proprietary financial information contained ~

L

in ' the Economic Analysis required -a significant expenditure of

resources. Permitting competitors'of CYAPCO to gain access to this

information could have a significant detrimental' impact. on the-

competitive position of the Company because 'others would not be

required to expend the same resou.rces for this information.

7.

The Economic Analysis is clearly confidential proprietary financial

information.

Accordingly, in order to protect this information,

CYAPC0 requests that the meeting with the NRC wherein these

financial matters will be discussed, be closed to the public.

The above seven paragraphs are true and accurate to the best of my knowledge,

information, and belief.

Executed this

/s day of March,1993.
