(Cl osed)

Infraction 50-335/80-14-01.

This item concerned failure to report to the NRC via Licensee Event Report the discrepancies identi-fied during the. Periodic Testing of Engineered Safety Features in 1979.

The'eport, has been submitted as LER 80-24.

Review of this LER and FPL letter L-80-181 indicate that'he matter is resolve (Closed)

Unresolved Item 50-335/80-35-08.

This item concerned the, power supply circuit for Power Operated Relief Valve(PORV)

1402 which was reported as being powered from a

vital source via Class 1-E components yet later was removed from a

non-class 1-E power panel.

Further investigation shows that the NRC requirement was to have the circuit breaker at the vital source be Class 1-E not the entire circuit from the vital source to the PORV.

In this case, the licensee originally met. the requireqent as reported and was taking additional action to further improve circuit reliability.

This item was not found to involve noncompliance.

Unresolved Items Unresolved items are matters about which more information is require to determine whether they are acceptable or may involve. noncompliance or deviations.

A new unresolve item identified during this inspection is discussed in Pa'ragraph 7.

LER 80-.52 Control Element Assembly Power Supplies The licensee-has'.

reported, during the Spring, and Summer of 1980 a

significant number of occasions

{20) where control element assemblies were

"dropped", i.e.,

automatically inserted into the core region, usually when the reactor was at power.

Investigation shows that this problem. was usually caused by a failed. power supply in the Rod Control Circuit Evidence:- of a heat correlation is strong..

With regard to the 1980'ccurances.,

the Ticensee had.

previously contracted because of power supply.: failures',

with, the Nucl'ear.

Steam Supply System.

{NSSS)

vendor Combustion: Engineering (CE), to provide. a more reliable. power supply system which. involved duality. of. power supplies The power supply vendor had also changed.

models of. power supply.

The licensee had changed to the..new power supply during the Spring 1980 refueling, installed the-hardware= to. allow dual power supplies, and returned the:

old power supplies to the vendor for modification; Upon modification

of the old power supplies, they were to have been installed as the dual units.

The new power supplies failed at such a rate that the old power supplies were re-installed singly and samples of failed new power supplies returned to both the NSSS vendor and the power supply vendor for evaluation.

No dropped CEAs have recently occured since this action was taken. 'hile no instances have occurred where CEA's have failed, to insert.

each dropped CEA is an unplanned transient both on core flux levels. and fuel'lad temperature.

Resolution of this problem will be followed up as Inspector Followup Item 50-335/80-36-03.

Timeliness of Licensee Event Reports.

During review of 1980 Licensee Event Reports, the inspector identified nine of 54-reports that were submitted to the NRC beyond the time limit of thirty days.

The majority of these reports, usually due on a

weekend, wire mailed the next working day.

The licensee indicated that their policy was to apply

CFR 2 criteria, which is used for licensing and enforcement correspondence.

No relief is mentioned in the Technical Specifications.

Region II Hanagement has ruled this practice acceptable for LERs,. but stated that. it did not apply to other Technical Specifica-tion time. limits the

day review of temporary procedure changes..

l No items of noncompliance or deviations were identified in the area. of LER submittal timeliness

Task. Action Plan. II,, E,. 4,. 1 Containment. Isolation Dependability.(NUREG.

0578 Item 2.1'.4)

The. inspector reviewed licensee action taken in accordance with the NRC positions.

Items: reviewed included.

NUREG, 0578 and amplifying letters; licensee responses dated January 11, and April 3, 1980; NRC staff.

evaluation dated April 1T,. 1980; and Plant Change/Modification package PQl565-79..

In addition to identification of all non-essential (in case of major accident)

containment penetrations, the licensee's action was to modify the control circuits for engineered safeguards.

such that actuation of each Safety Injection Actuation Group, in turn, actuates the correspondingly numbered.

Containment Isolation Group in the same train..

The design is such. that: a containment isolation signal does not.

initiate. safety injection.

SITE EMERGENCY DRILL A site emergency drill coordinated with Local and State Disaster Preparedness Agencies was conducted November 13, 1980 with a pre-drill conference among site monitors on November

and two post drill critiques-a public critrique conducted by the State of Florida on November 14 in Ft.. Pierce and a plant critique conducted by the plant emergency coordinator on-site on November 17, 1980.

The off site (State)

portion of the drill was a

major disaster preparedness drill exercising communications and coordination of radiation monitoring forces, County Sheriff and fire departments, State Police including airborne cabaility, and county disaster preparedness personnel.,

Communications monitored in the control room at the plant indicated no major problems with communications or coordination.

The site portion of the drill was conducted while the reactor remained at power.

This portion included control. room walk through of actions taken,

"drill" emergency reports notifying agencies and corporate offices in accordance with the.

emergency plan, a first aid drill involving a contaminated casualty and site evacuation..

The number of

'rill monitors appeared adequate and observation by the inspectors of drill monitor activities revealed'o-items of concern in this area.

The site evacuation was expeditious.

Observation by the inspectors of regrouping and dress-out of re-entry terms revealed no items of concern in this area.

The inspector will pursue.

as Inspector Followup Item 50-335/80-36-04-'eview of the written 'plant drill critique and any corrective actions identified therein by the licensee.

13.

Plant. Operations The inspector monitored control room operations frequently during the inspection.

Areas monitored included shift staffing, 'operational parameters, surveillance testing and alarm indications.

Discussions with the operating staff and plant; management.

were, held frequently.

Significant areas discussed included. planned. activities,. plant. status, and. technical'esponses to IE: Headquarters information requests.

The, inspector.

conducted several tours. of. plant areas.

Observations were.

made. of'ork in progress;, of'lant housekeeping-and vital area controls.,

No items. of noncompliance: or deviations were identified in this are ~ ~
