Examination Summary: Written examinations and operating tests were administered to nine Senior Reactor Operator candidates limited to fuel handling (LSR0).

All the nine candidates were previously licensed at Limerick Units 1 and 2 as LSR0s and received waivers that the written and operating portions of the examination will involve " differences" in procedure and design between Peach Bottom and Limerick units.

The written examination was prepared by the facility as previously agreed to by NRC, but was reviewed, administered, and graded by the facility and NRC in parallel.

Both grades were identical. The operating test was prepared, administered, and graded by NRC.

All nine candidates passed the examinations.

Within this report, individual strengths and deficiencies were listed as feedback to the licensed operator training program.

DETAILS

.

1.0 Introduction and Overview The NRC examiners administered written examinations and operating tests i

to nine LSRO candidates.

The examinations were administered in accord-

.

ance with NUREG 1021, Examiner Standards, Revision 6.

The draft standard l

ES-701, Administration of Senior Reactor Operators Limited to Fuel Handl-

!

ing Fuel Handling (LSRO) Examinations, Revision 6, was used as guidance to the extent possible.

Further, as approved.by the Of fice of Nuclear Reactor Regulation, Operator Licensing Branch, the NRC staff administered a " differences" examination since the candidates were already licensed as fuel handlers at Limerick, Because of similar procedures and designs in fuel handling

&

equipment between the two facilities, the examination primarily-tested'

differences between the facilities in the subject areas.

The differences examination also involved the licensee proposing the written portion, subject to approval by NRC staff.

The results of the examinations are summarized below.

l l-3.0 Pre-Examination Activities

,

i 3.1 Examination Scope Meeting l

A meeting between NRC and PECO was held'at the NRC Region I of fice at King I

of Prussia, Pennsylvania, on November 2, 1990, to discuss the scope of the

'

examination.

During this meeting, it was agreed that the' draft standard ES-701, Administration of Senior Reactor Operator Limited to Fuel Handling (LSRO) Examinations, be used as guidance for the' conduct of the-examination.

3.2 License Application Review The license applications were reviewed in accordance with NUREG 1021, Examiner Standards, Revision 6.

The applications contained sufficient

information to determine the eligibility of the applicants to appear for the examination or to grant the waivers as requested.

l 3.3 Examination Preparation The written examination and operating test were prepared in accordance with NUREG 1021, Examiner Standards, Revision 6. As noted in Section 1, the written examination was prepared by the facility and the operating test was prepared by NRC.

The reference material provided by the licensee was found adequate for the preparation, i

3.4 Pre-Examination Review Prior to edministration of the written exaniination, on December 6,1990, the NRC reviewed the examination at the Regional Of fice with the facility representative who prepared the examination. All NRC con.ments were discussed and resolved during the review session.

The examination was revised-to incorporate those changes.

The facility individual involved with preparation and the review of the examination materials signed-security

.

agreement to ensure that there was no compromise of the examination.

3.5 Entrance Meeting An entrance meeting with the licensee was held on December 18, 1990, at its training facility. The purpose of the meeting was to discuss the plan and schedule for the examination.

(

4.0 Examination - Related Findings and Conciusions The following is a summary of the strengths and deficiencies noted during the administration of the written examination and operating tests.

This information is being provided to aid the licensee-in upgrading the LSR0 training programs.

No licensee written response is required.

4.1 Written Examination Strengths The knowledge of the following topics-(the related question number in parathesis) was noted as strengths:

Refueling interlocks (Question 3)

Staff working hour restrictions (Question 4)

Diesel Generator automatic start signals (Question 11)

a Technical Specification requirements for -SRM (Question 12)

LSR0 overlap requirement during shif t turnover (Question 14)

>

e - ~

,

.

.

.

Limit on maximum number of fuel bundles that can be transferred per

day during initial core off-load or during a fuel reshuffle (Question 17)

The types of radiation that can be measured by DRD and TLD (Question

18)

Suction source for the Shutdown Cooling System (Question 19)

Response of Electrical Distribution System for a LOOP signal

(Question 22)

Locations of CCTAS and the official sign off copy (Question 27)

Methods to control contamination (Question 28)

Isolation signals for Reactor Building HVAC (Qrestion 30)

Access restrictions to Drywell during irradiated fuel movements

.

(Question 35)

Emergency exposure limits (Question 36)

-

SLC system controls and interlocks (Question 37)

i Normal cooling medium for the FPC system (Question 40)

Technical Specifications for inoperable LPRM (Question 46)

Reason for shaking the grapple while the fuel assembly is going into

the core (Question 49)

Technical Specification Safety Limit - bases concerning the 75 psig

RHR shutdown cooling mode isolation (Question 50)

Definition of TS Surveillance Frequency and its margin (Question 51)

Conditions for terminating fuel handling operations (Questicn 52)

Bases for Technical Specification requirement for minimum water

level in spent fuel pool (Question 53)

Deficiencies l

'

The knowledge of the following topics was noted as deficiencies:

HPSW pumps response to high drywell pressure (Question 1)

Purpose and operation of Core Spray Leak Detection system (Question 8)

_

.

.

'

Reasons to dis:ontinue the mcVement of fuel or other equipment

(Question 23)

Plant Housekeeping Zones end methods of cleanliness controls

(Question 39)

Effect of loss of instrument air on SLC storage tank level

indication (Question 42)

Service Water pump trip signals (Question 44)

4.2. Operating Test Strengths With respect to the applic'nts' training limited to the differences

between Limerick and Pear' Bottom, the applicants demonstrated good knowledge in administra' ive topics, systems, and procedures irnportant to fuel handling oper-lons at Peach Bottom, except those noted as deficiencies.

During the fuel handling portion of the operating test using dummy

fuel bundles, the applicants demonstrated their ability to transfer fuel from one location to another in the Spent Fuel Pool.

The applicants, in general, demonstrated their knowledge to interface

with maintenance crew and the control room operating crew for proper conduct of the interfacing activities during refueling operatiors.

Deficiencies During the performance of' Job Performance Measures (JPMs), the appli-a ants generally exhibited difficulty in locating certain system valves or instrumentation.

The systems were:

Reactor Building HVAC, Reactor Building Closed Cooling Water, and Fuel Pool Cooling. The root cause of this deficiency appears to be inadequate training in performing JPMs associated with systems important to fuel handling.

The licensee indicated that LSR0s are not normally responsible for these types of job functions.

However, the license plans '.o provide the required remedial training to conform to NRC expectations in the Examiner Standard (ES-701), prior to January 10, 1990.

5.0 Exit Meeting An exit meeting was conducted on December 20, 1990, following the admi-nistration of the examination.

The licensee representatives that attended the meeting are listed in Section 2. of this report.

-

_

. _ _

<

.

.

The generic strengths and deficiencies noted on the operating examinations were presented (see'Section 4.2 of this report).

General observations by the examiners while administering the operating tests were discussed.

The chief examiner stated that the results of the examinations would not be presented at the exit meeting, but would be contained in the examination report and that every effort would be made'to send the results in approxi-mately 30 working days.
