Addition Throttb Valve Found Hispositioned. As part of the assessnent of the irrpact of this event th evaluation by Sargent & Lundy Engineering.e licensee requested an

!

!

The concerns evaluated were if the systen: had been called upon under this condition, what l

.

would the affect be on containment hydrogen generation and what

,

would be the corrosive affect on the environrent qualification of l

i

'

theequipment(EQ). The licensee contractor developed a CS flow l

model and calculated that the caustic concentration would have a i

'

pH of 12.9 (confirned by NRR) for about 30 minutes or until dilution would occur from the refueling water storage tank by continued

,

operation of the CS system.

The analysis also developed projected i

'

hydrogen buildup under this ccodition based on the presence of aluminum and zine (most affected) in the containment. Although

,

l the technique seemed appropriate, the evaluations were performed i

at 10% and 50f greater than the original data at pH of 11.0 rather

,

l than at 100% greater which would correspond to the pH of 12.9.

j The results showed that the dangerous explosive concentration of

4% hydrogen would not be exceeded until in excess of 260 hours0.00301 days <br />0.0722 hours <br />4.298942e-4 weeks <br />9.893e-5 months <br /> after the LOCA, giving reasor.able time to make use of the hydrogen i

'

l recontiners.

With respect to the EQ issue, the licensee noted that most equipnent

!

operates instantaneously and prior to serious corrosive oegradation

'

and that most EQ equipnent is shielded by other equipment and

structural materials, and that the duration of exposure to the i

high pH would be about 30 minutes. This confirmed the resident f

inspectors previous calculation and knowledge of the LOCA procedures.

The licensee representatives confided that the EQ equipment was

!

,

t not qualified for a pH exposure of this ma In addition,

!

the licensee acknowledges the inspectors' gnitude.

conscent that this matter is requiring an unacceptable amount of time to eyeluate. This was i

primarily due to the recognition that this should have had a

,

priority consideration. The Office of Nuclear Reactor Regulation is assisting the resident staff in evaluating this isst.e.

Licenseo Event Report (LER) (92700)

l

j Through direct observations, discussions with licensee personnel, and I

review of records, the following event reports were reviewed to determine that reportability requirements were fulfilled, that innediate corrective

'

action was accomplished, and that corrective action to prevent recurrence had been or would be accomplished in accordance with Technical l

Specifications (TS):

I a.

{ Closed) 456/89020.LL: Failure to verify safety injection accTnuletor (5IA) boron concentration within specified time interval due to programmatic deficiency. At 8:28 a.m., on December 23, 1989,

!

two SIA levels were raised with addition of 105 gallons to one, and 189 gallons to the other. Boron concentration is required to be

'

verified within six hours after each volume increase of 70 gallons.

l At8:36a.m.,theControlpoomSupervisor(SCRE)telephonedthe

Chemistry Supervisor (CS) and requested the samples.

The CS entered the request in the logbook intending to assign the task when personnel became available.

The CS was not aware of the six hour l

requirement. When the CS was relieved at 11:00 a.m. by the after-

noon shift CS, the tample was not mentioned. At 3:30 p.m., the i

l SCRE contacted the CS and after checking the logbook, the CS

'

concluded that the samples had not been taken. A technician was

innediately dispatched to sample the SIAs, they were within I

acceptable limits.

The cause of this event was the failuro of the l

SCRE to assure timely com)letion of the required analysis and the l

i CS not being aware that t1ere was a six hour time limit on the l

samples. A contributing factor was that there was no program to monitor routine Technical Specifications samples being performed on a non-routine basis which do not require action statement entry.

Corrective actions included:

the CS issuing a memo to all chemistry

,

department personnel regarding sample time requirements for SIAst Operating Procedure, Bw0P SI 5, will he revised to include an Action Requirenent sheet for sampling; a review of Chemistry Surveillance

cover sheets will be performed to insure that time requirements for

ResponsetoinspectorInouiries(71707{

During the inspection period, the inspectors identified a number of

[

issues requiring followup by the licensee.

These are referred to as

!

  • Blue Sheets" and the following is a summary of the issues and responses:

a.

Inquiry 90-004 - Unusual Oder in a Cable Spreading Room l

On about February 21, 1990, an ocor similar to ozone was noted in the Unit I lower cable spreading room.

This is an OSHA concern.

The licensee hazardous materials representative and the Industrial

Hygiene and Safety Advisor monitored the area with an ozone detector and none was detected. An odor was detected that may have been from

,

t cable pulling compound, paint epoxy, or residual material from the fire protection system.

This was not considered to be a hazard.

b.

Inquiry 90 005 - ECCS Room Cooler Dirt on Fins and Fin Damace

.

During a plant tour, on February 6,1990, the inspectors noted dirt accumulated on the fins (potential blockage) and some fin damage i

on several ECCS room coolers.

These were cleaned and the fins

,

repaired.

It was noted that this was an inspection sattple and only

t. hose coolers identified were checked by the licensee.

This lack of

I follewup or narrow span of correction was discussed with station management during orie of the routine exit briefings, c.

Inquiry 90-006 - Unsecured Spare Circuit Breakers and Ground Test j

Device During a routine plant tour on February 6,1990, the inspectors noted spare circuit breakers outside of the switchgear cabinet damagingtheClass.e.freetorollabout,creatingapotentialfor were unsecured 1 2E power supplies. These were in the 4.1 and

.

6.9 KV switchgear rooms. The licensee promptly placed the spare breakers in the spare switchgear cubicles.

However, about one week

later, ground test devices were found in the same condition. These were chained to stanchions to prevent riovement.

l d.

Inquiry 90-009 - NWR Labels on control Room Annunciators and Ins tr.lments The inspectors noted what appeared to be on excessive number of control room annunciators and instruments with Nuclear Work Request (NWR) stickers indicating a problem or potential problem. The inspector inquired as to whether there was a mechanism to remove these when the NWR was completed. This was in the interest of the control room operators and their confidence in the validity of the alarms and instrument indications. An operating engineer conducted

'

a study of backlog NWRs to verify the appropriateness of the NWR stickers and assure those present were valid.

In addition, the inspectors were provided a copy of Special Operating Order

,

50-ST-0009, Rev.1, dated July 3,1989, giving instructions to

!

assure that the NWR stickers are removed upon completion of the work. This response was found to be acceptable and the effectiveness will be monitored during future inspections.

Other issues raised were minor end responses were acceptable, i

No violations or deviations were identified.

8.

Monthly Maintenance Observation (62703)

Station naintenance activities affecting the safety-related systems and con.ponents listed below were observed / reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides and industry codes or standards, and in conformance with Technical Specifications.

The following items were' considered during this review:

the limiting conditions for operation were met while components or systems were i

During the periodic maintenance work, the licensee identified a problem with water intrusion in the motor grease compartment, which was evaluated and repaired.

2A RHR pump seal and bearing replacenent.

'

The inspectors monitored the licensee's work in progress and verified thet it was being performed in accordance with proper procedures, and approved work packages, that 10 CFR 50.59 reviews and applicable drawing updates were made end/or planned, and that operator training was conducted in a reasonable period of time.

No violations or deviations were identified.

9.

Monthly Surveillance Observation (61726)

The inspectors observed surveillance testing required by Technical Specifications during the inspection period and verified that testing was performed in accordance with adequate procedures, that test instrumentation was calibrated, that limiting conditions for operation were met, that removal and restoration of the affected components were accompitsbed, that results conforrad with Technical Specifications and procedure requirements and were reviewed by personnel other than the ir<dividual directing the test and that any deficiencies identified during the testing were proper,ly reviewed and resolved by appropriate m6nagement personnel.

10.

Preparation for Refueling and Initiation of a Refuel Outage (60705. 60710)

During the inspection period, the inspectors monitored the licensee's

<

> reparation for the first refueling outage on Unit 2.

This involved.

l aut was not limited to, final receipt, opening, inspection, storage of I

new fuel as described in inspection report 456/89032(DRP);457/89030(DRP),

end inanagement and coordination of planned work group activities, i

,

On March 16 1990 Unit 2 was shut down comencing its first refuel

!

outt.ge. This cullnineted a first fuel cycle run of 168 days.

l No violations or deviations were identified.

I 11. Containinent Air Sampling Panel (CASP) (93702)

l Operability / Availability Challenged i

On March 9,1990, licensee staff members informed the resident inspectors l

of a problem identified with the portion of the Post Accident Sampling

'

system where the Unit 1 CASP would not operate as designed.

The CASP is

!

for sampling the contairment atniosphere to menitor radioactivity levels

!

'

following an accident. During a drill on February 23, 1990, the key

!

lock switch that initiates the sampling sequence would not operate.

Investigation revealed that the wires to the switch were not properly

,

terminated to terminals in the back of the CASP. Evidence indicated that i

the wires were disconnected intentionally and there was no sign of

{

maliciousness in that the wires showed no insulation damage and lugs for

~

connection to terminal screws were undamaged and intact. A histor< cal

review revealed that both Unit I and 2 CASPs were proven operable during

,

preoperational test in March 1987.

Subsequently, during a drill on Jnit 2, apparently in March 1988, a similar f611ure occurred. The prompt i

corrective action at the tine to meet the urgency of the drill was to i

swap the lock switches between units.

The inferior lock switch was

.

placed in the Unit 1 panelt however, there was no record of this and no

!

Nuclear Work Request was generated for final repair.

This is based on

recollection of chemistry department personnel.

However no one could

!

recall or would confide specifically low or when the swap, occurred.

t At the tire of the discovery, the licensee was developing a surveillance for periodic testing of the CASP and is presently committed to have the surveillance implenented by November 1990.

The Unit 1 CASP lock switch was replaced and satisfactorily tested on

'

March 13, 1990.

!

This issue has been the subject of a review by Region III radiation I

specialist and is addressed in Inspection Report 50-450/90009(DRSS);

50-457/90009(DRSS).

!

No violations or deviations were identified.

personnel was reviewed by the inspectors during the witnessing of the licensee's performance of routine surveillance maintenante, and operationelactivitiesandduringthereviewofthelicensee'sresponse l

to events which occurred during the intpection period.
