EXECUTIVE SUMMARY

River Bend Station

NRC Inspection Report 50-458/97-01

i

!

This inspection evaluated the competency of a senior operator license applicant for '

issuance of an operating license at the River Bend Station facility. -The initial license

examination was developed by the facility using the pilot process program guidance  !

contained in Generic Letter 95-06 and NUREG-1021, Revision 7 and Supplement 1, .  !

" Operating Licensing Examiners Standards." An NRC examiner reviewed, approved, and I

administered the examination. The initial written examination was administered to the

applicant on January 27,1997 by both facility and NRC proctors. The operating test was

administered on January 31,1997 and March 12,1997. The senior operator applicant  ;

'

displayed the requisite knowledge and skills to satisfy the requirements of 10 CFR 55 and

was issued the appropriate license, j

l

Ooerations

• The draft examination outlines as submitted were not adequate for administration. -

The operating test control room systems proposed were of narrower scope than t

allowed by NUREG-1021 (Section 05.1.1).

!

• Two potential examination compromises occurred, which were contrary to

examination security practices agreed to by licensee staff (Section 05.1.2).

• The applicant passed all portions of the initiallicense examination which satisfied i

the requirements of 10 CFR 55.33(a)(2), and was issued the appropriate license in

accordance with 10 CFR 55.51. However, the applicant performed marginally on

the written examination (Sections 04.1,04.2).

• The licensed operator requalification program performance was reviewed to

ascertain operator performance. The licensee's licensed operators performed

acceptably during recent licensed operator training cycle examinations

(Section 05.3).

04 Operator Knowledge and Performance

04.1 Initial Written Examination

a. Inspection Scope

The written examination was co-administered by the licensee training representative

and the NRC examiner onsite on January 27,1997, in accordance with guidance

provided by the chief examiner. This action was taken because of a potential

compromise of examination securits/ which occurred the week prior to the written

examination week. The NRC examiner graded the written examination and the

licensee staff performed a postexamination analysis. As a result of the licensee's

post examination analysis, postexamination comments were submitted to the NRC

on March 3,1997.

b. Observations and Findinas

The applicant passed the written examination with a score of 80.4 percent. After

final NRC review it was determined that the applicant missed 19 out of 97 l

questions. The missed questions were reviewed by both the licensee and the NRC '

,

to ascertain whether a generic weakness or training deficiency existed. No specific

l generic weakness was identified. However, the postexamination review determined

that the applicant demonstrated a potentially weak overall system knowledge in that i

questions related to detailed systems knowledge were typically missed. As such,  !

the applicant performed marginally on the examination.

,

l

'

c. Conclusions

The applicant passed the written examination portion of the license evaluation.

Evaluation of the applicant's performance indicated a potential weakness in the

depth of the applicants overall system knowledge, i

04.2 Initial Ooeratina Test

a. Inspection Scoce

The NRC examiner administered the various portions of the operating test to the  !

applicant on January 31 and February 12,1997. The applicant participated in two

dynamic simulator scenarios; one while acting as the reactor operator at-the- 1

controls and acting as the control room supervisor in the second. The applicant ]

also received a walkthrcugh test which consisted of ten system and four ]

administrative area tasks and questions. I

b. Observations and Findinas

l

During the simulator portion of the examination, communications practices observed

in the simulator were good. Operator performance in the simulator was also good.

The applicant passed this portion of the examination and demonstrated good

command and control skills.

During the job performance measure portion of the examination, the applicant

demonstrated good plant knowledge and a familiarity in locating components,  !

support items, and reference material. The administrative portion of the I

I

examination was also administered during the plant walkthroughs. The applicant

demonstrated a high degree of familiarity with the plant's administrative functions

and requirements. The applicant passed these portions of the examination.

c. Conclusion

The applicant passed the operating test portion of the examination. Good

communication skills as well as command and control skills were observed. The

applicant demonstrated a high degree of familiarity with plant procedures and in

locating components in the plant.

05 Operator Training and Qualification

05.1 initial Licensina Examination Development

The facility licensee developed the initiallicensing examination in accordance with

guidance provided in Generic Letter 95-06, " Changes in the Operator Licensing

Program."

05.1.1 Examination Outline

a. Scoce

The licensee submitted the initial examination outlines on November 21 and

December 10,1996. The chief examiner reviewed the submittats against the

_ _ - -. . _ _ __ _ __ _ _ _ _ _ _ _ . - _

l

.5

requirements of NUREG-1021, " Licensed Operator Examiner Standards" Revision 7,  !

Supplement 1, and NUREG/BR-0122, " Examiner's Handbook for Developing

Operator Licensing Written Examinations." Revision 5.

b. Observations and Findinos

The chief examiner determined that the initial examination outlines generally

satisfied the above requirements. However, minor changes to the written l

examination outline were made by revising a knowledge / ability designator. The

chief examiner also noted that the job performance measures outline did not meet

the requirements of Examiner Standard 201-3, item 3b, in that safety functions for

Job Performance Measures 4 and 8 were repeated which resulted in the job

performance measures not covering at least seven different safety functions. Other

observations by the examiner were minor. The comments on the outlines were

discussed with the licensee author and revisions were made and submitted along

with the draft initial examination.

c. Conclusion

The draft examination outlines as submitted were not adequate for administration

The operating test controt room systems proposed were of narrower scope than  ;

allowed by NUREG-1021.  ;

i

05.1.2 Examination Packaae

a. Inspection Scope

The licensee submitted the completed draft examination package between

December 10,1996 and January 6,1997. The chief examiner reviewed the

submittal against the requirements of NUREG-1021, " Licensed Operator Examiner

Standards" Revision 7, Supplement 1 and NUREG/BR-0122, " Examiner's Handbook

for Developing Operator Licensing Written Examinations," Revision 5.

b. Observations and Findinas

l

The draft written examination was transmitted by the licensee to the NRC in a letter

l

dated December 10,1996. The draft written examination was considered properly

l

discriminating. It was responsive to a knowledge and abilities sample plan

l submitted by a letter dated November 21,1996, which was approved by the chief

l examiner. The chief examiner approved the draft examination based upon a review

i

'

of reference material provided with each question. Few substantive comments

were made with most comments of an editorial nature. The written examination

-

was considered adequate as submitted. In response to chief examiner comments,

the licensee enhanced questions 35,43,55,56,62,69,70,76,77,78,81,88,

90, 94, and 97.

i

l

. _ . _ - .- . - . .

Additionally, due to a potential examination compromise, other questions were

replaced. The compromise occurred when a licensed operator, with examination

content knowledge and on the security agreement, interacted with the applicant to

complete systems qualification the week before the examination. The control room

supervisor who was also on the examination security agreement observed the

operator and applicant and halted the activity in progress. The licensee initiated a

condition report, conducted investigations and evaluated the draft examination for

possible overlap with the system qualification job task evaluations. As a result, the i

licensee replaced questions 19 and 33 on the written examination. There was no

indication of an actual compromise to the examination.

The licensee provided postexamination comments on seven written questions which

are attached to this report (Attachment 3). Review of the licensee's submitted post

examination comments resulted in accepting licensee recommendations in deleting

three questions (34,41, 59); a change in the correct answer to one question (15);

and the acceptance of two correct answers for another question (46). The review

also determined that the licensee's recommendations for questions 80 and 89 were

not valid and the questions were retained. Additionally, the NRC reviewed other

questions and determined that question 27 had two possible correct answers. As a

result, after incorporating these changes, the applicant received a score of 78 out of

97, equivalent to 80.4 percent. The as-given written examination and answer key

are attached to this report (Attachment 4).

Because postexamination reviews identified changes based on technical accuracy of

over 5 percent of the written examination, the licensee was asked to explain why

their staff had failed to identify these issues before the examination administration

and to describe corrective actions planned to assure that the next licensed operator

written examination is of higher quality. 1

The licensee submitted three dynamic scenarios, including one backup scenario

which was not used during the examination. The chief examiner had few

comments related to the proposed scenarios. Some general comments related to

statements for operator actions being explicit were made. The second scenario did

not meet the criteria of Examiner Standard 604-1 for contingency actions after

emergency operator performance entry. Other minor spelling errors were also

noted. The licensee reviewed the comments and made the necessary revisions prior

to onsite validation the week of January 27,1997.

During the week of January 27,1997, a second potential examination compromise

occurred when a licensed operator involved in simulator scenario validation

inadvertently left some rough notes related to the first scenario in the simulator, j

The notes were disenvered immediately afterward by the requalification crew i

entering the simu;ator er requalifi:ation training. The licensee took prompt actions

to enter the requalification New c 1 the security agreement, brief all individuals on

the security agreement about . ,ncident and the need for continued vigilance since

the examination was postponed. Wnile the second incident was unrelated, the two

l' events caused the licensee staff to reevaluate the adequacy of their security l

1

measures and to take both short and long-term corrective actions. The licensee

[ replaced the entire set of simulator scenarios, including the backup scenario, to

] ensure that no overlap existed with the potentially compromised scenario. The

j dynamic simulator portion of the examination was postponed until the week of

l February 10,1997.

i

! The chief examiner validated the replacement scenarios during the week of

l February 10,1997. The examiner verified that the replacement scenarios contained

j no overlap with any of the removed scenarios. The examiner also noted that the

, replacement scenarios required modification before administering to ensure the

i examiner standard guidances were fully met with regard to Examiner Standard 301-

5, " Transient and Event Checklist."

1

l The licensee also submitted both job performance measures and questions to cover

] the administrative section of the walkthrough test. The chief examiner reviewed the

i job performance measures and noted a number of comments which were discussed

j informally with the licensee examination author. Most of the comments related to

i the adequacy of the followup questions (e.g., multipart answers required, whether

) question is open or closed reference). Some other com_ments resulted in the job

4 performance measure being replaced. For example, job performance measure

" Manually Startup Standby Gas Treatment Train A taking a suction on Outside Air"

I was considered too simplistic in that the entire jo'o task only had two active steps

! performed by the applicant. In another instance, a job performance measure had

'

potential overlap with an event in one of the scenarios. The licensee was very i

responsive in reviewing the comments and making the necessary revisions. l

e

l c. Conclusions

t

i

Overall, the written examination and operating test materials submitted were of fair

quality and discriminated at the appropriate license level. However, because of NRC

,

comments on the initial draft examinations and potential security compromises, a

4 number of revisions and revalidations prior to examination administration were

required. Additionally, because the licensee submitted over 5 percent of the written

examination for postexamination comment, the licensee's written examination

prereview was not of sufficient quality.

05.3 Licensed Operator Reaualification Procram Status (IP 71001)

a. Scope

This portion of the inspection reviewed results from the past two licensed operator j

requalification training cycle examinations and conducted discussions with key i

operations training managers,

b. Observations and Findinas

i

The inspector noted that no operating crew failures occurred during the

. September 2 through October 11,1997, requalification training cycle. Further,

during the annual requalification examinations conducted between October 14 and

December 13,1996, one crew out of nine failed the examination. It was noted that

the crew failure during the annual examination was not one of the same two

operating crews which had difficulty in the simulator during the past August 1996

cycle training. Additionally, the inspector discussed requalification training status

with a key training manager and was informed that crews were taking greater

a

ownership responsibility for their training to include better feedback and self-

critiques of their simulator sessions.

c. Conclusion

The inspector concluded that operator performance based upon recent

4

requalification cycle training and the annual requalification examination had been

,

acceptable.

E2 Engineering Support of Facilities & Equipment j

E2.1 Review of the Uodated Final Safety Analysis Reoort Commitments  !

A recent discovery of a licensee operating their facility in a manner contrary to the

Updated Final Safety Analysis Report description highlighted the need for a special  ;

focused review that compares plant practices, procedures, and/or parameters to the l

Updated Final Safety Analysis Report descriptions. While preparing for the l

inspection discussed in this report, the inspector and the licensee reviewed the I

applicable portions of the Updated Final Safety Analysis Report that related to the  !

areas inspected. The inspector noted that the Updated Final Safety Analysis Report )

training commitment was inconsistent with the observed plant practices,  ;

procedures, and/or parameters in that commitments stated in the licensee's l

Technical Specification. Specifically, Section TR 5.3, " Licensed Operator

qualifications," of the Technical Specifications committed to the minimum

qualifications of the supplemental requirements of NRC letter dated March 28,

1980. The Updated Safety Analysis Report, Section 13.2.1 commits individual I

training programs to comply with Regulatory Guide 1.8 and ANSI /ANS 3.1-1978. l

The licensee has implemented a systems approach to training program in

accordance with Generic Letter 87-07. Further, the licensee's

Procedure TPP-7-009, " Hot License Operator Training and Qualification Program," is

designed to meet the requirements of ANS-3.1-1981 and Regulatory Guide 1.8.

The licensee committed to revise the Final Updated Safety Analysis Report and

Tc, L dcal Specification to reflect their current training program commitments and

reve.nents.

Question #59; NRC agrees, delete question.

Question #80; NRC disagrees. Keep as is. The question discriminates whether or not the

! applicant knows that with a loss of the "A" RPS Bus, the condenser air removal pumps are

,

lost. As a result, main condenser vacuum will begin to decrease. The selection of (d) as

j an answer requires presumption that other leaks occur. While instrument air pressure will

decrease in time, the plant response is protracted; the decrease in condenser vacuum

begins almost immediately. Therefore, answer (b) is the most plausible answer based upon )

the conditions provided in the stem of the question.  !

Question #89; NRC disagrees. Keep as is. The question does not require the applicant to

. know the test criteria, but does require the applicant to understand where to look in order I

to call the rod "sdow" or " inoperable". This question was accepted during the licensee's

i prereview process. Further, the training learning objective requires the student to identify

} the TS operability requirements for the CRD Hydraulic and CRD Mechanism systems.

Question 15 Comments Recommendations !

$

l

The use of the term " Normal Service Water" implies the

manipulation of Non Safety-Related components which

could be documented per ADM-0022," Conduct of

Operations." The use of the term " surveillance testing"

implies the manipulation of Safety-Related components

during surveillance testing which are documented per

ADM-0015," Surveillance Testing." Given the disparity

in the stem of the question, ADM-0015 is no longer the

ONLY reference to govern this unusual operation.

ADM-0022," Conduct of Operations" provides guidance

for operational activities and therefore becomes an

expected response.

. ADM-0022, Section 6.3 " System Check Lists," could

provide guidance,

" . system checklists are used for establishing and

confirming the status of equipment and systems.

proper system configuration is assured and

maintained by use of administrative controls

(i.e., SOP, MDL, OSP-0014, Temp. Alt.) "

. ADM-0015, Step 7.11.5 would provide guidance for

repositioning valves required to be manipulated as

part of the surveillance test package.

6.2.2. Routine procedural actions that are frequently perfonned may

not necessitate the use of a procedure. If there is any doubt as

to the procedural action by the individual performing the job,

the procedure must be in hand.

6.2.3. Entry conditions of emergency procedures shall be committed

reverification of the initial conditions is required as

determined by the OSS/CRS.

6.2.6. In the event that an original procedure checklist, STP or

tagging order becomes contammated the information should

Question 34

Second case, although an automatic start signal has

been received, the statement in the stem "It has been

determined that NO VALID start signal condition

exists" implies no start signal or condition is

currently present. In this case, use of the emergency

trip button is not appropriate (see SOP-0052

precaution 2.1.22) and not required to stop the

machine. Both "c" and "d" would stop the diesel

under the circumstances described.

Note: The Diesel Generator mode switch positions

on the panel are " REMOTE" and " LOCAL" instead

of" REMOTE MANUAL" and " LOCAL

MANUAL". However, since both positions simply

set up the manual control functions, this level of

discrimination is not appropriate for determining the

i

distracters are incorrect. (i.e. to eliminate "c" and

"d" the candidate would need to know the exact

switch nomenclature).

to depress the "STOP" pushbutton on IE22*PNLS001 engine panel or by

using the control switch on lH13*P601, (depending on where control is).

This will drop out the K1 relay which seals in upon a start. Failure to do so

1.3.2.7 Drive Water Header (Figure 1)  !

1. Description *

,

There are 4 drive water headers each is equipped with a stabilizing unit. The stabilizing

valves are controlled automatically by RCalS. They will close during control rod

movement to divert water from the cooling water header to the drive water header. This

is done to maintain a constant system pressure during rod movement.- The stabilizing

valve units consist of two normally open parallel solenoid operated valves. Needle valves

down stream of each stabilizing valve are set such that each valve passes 2 gpm. On a  ;

control rod insert both stabilizing valves close which provides a 4 gpm flow to the bottom  !

of the drive piston. On a control rod withdraw one stabilizing valve closes which

provides a 2 gpm flow to the top of the drive piston.

t Drive water pressure is manually controlled by Pressure Control Valve Cl1-MOVF003 at

reactor pressure plus 250 psig. Drive water pressure may also be controlled by a manual

bypass around the Pressure Control Valve. Should drive water exceed 550 psid a relief

valve opens relieving to the cooling water header. This feature avoids the possibility of

excess water pressure causing excessive control rod drive speeds.

Question 41 Comments Recommendations

SOP-0002," Control Rod Drive System" 4.1 Section

" Placing the CPS System in Operation," states that

system flow and drive pressure will need to be

adjusted to obtain a d/p of 250 psid. Throughout this

procedure, during normal system operations and

evolutions, drive pressure will need to be adjusted

to obtain and maintain a d/p of 250 psid. STM-

A0052.00 states that," Drive water pressuce is

manually controlled by PCV at reactor pressure plus

1.3.5.3 Remote Controls and Indications

The indicators on H13-PNLP680 show the pressure drop across each seal during

normal operation (see Figure 5). During normal operation, No. I seal cavity pressure

should read approximately 10-15 psig greater than RPV pressure, and No. 2 Seal

Cavity pressure should read approximately 1/2 the value of seal cavity No.1. If the

No. I seal has a gross failure, seal cavity No. 2 pressure increases to the value of seal

cavity No. I and RECIRC PUMP A(B) SEAL STAGING HIGH/ LOW FLOW (H13-

PNLP680) alarms. Should seal No. 2 fail, the RECIRC PUMP A (B) OUTER SEAL

HIGH LEAKAGE annunciator (H13-PNLP680) alarms, the No. 2 Seal Cavity

pressure lowers, and the RECIRC PUMP A(B) SEAL STAGE HIGH/ LOW FLOW

(H13-PNLP680) alarms.

If both seals fail, the pressure in cavity #1 remains about the same. The pressure of

cavity #2 may go higher or lower depending on which seal is worse. Additionally, at

this point, there is significant seal leakage, which is indicated by a rise in

unidentified leakage. Both the RECIRC PUMP A(B) SEAL STAGING HIGH/ LOW

FLOW annunciator (H13-PNLP680) and the RECIRC PUMP A(B) OUTER SEAL

HIGH LEAKAGE annunciator (H13-PNLP680) alarm.

It is also possible to have a partial seal failure which would cause pressure

indications to respond as described above but not cause an alarm actuation.

1.3.5.4 Automatic Functions

The Reactor Recirculation Pump A(B) Seal Flow Outlet Isolation Valve (B33-

FVF075A(B)) is now operable. The valves are OPEN regardless of switch position if

the respective recire pump is on line. The valves open if OPEN switch is depressed

and the respective pump is off-line. The valves closes when AUTO switch is

depressed and the respective pump is off-line.

Key Answer / Comments Recommendations

Question 59

Following a normal reactor scram, at what point must the Answer: d Throw out question

At-The-Controls Operator be alert for narrow range reactor since there are 3 possible

water Icvel indication " outgassing" or " notching"? (Assume Reference: GOP-0002 correct answers.

the Reference Leg Backfill system is NOT in service.)

a. If the cooldown rates exceed the Technical Comments:

Specification limits.

Response (a) and (b) are also correct.

b. If the MSIVs close and pressure control is on the

Safety Relief Valves. GOP-0002, P&L 1.29,"If the Reft.rence Backfill

System is not in service, then notching ... may occur

c. When the last Feed Pump is removed from as reactor pressure is lowered. A slow cooldown

service. rate will decrease the effect of degassing the

reference leg."

d. As reactor pressure decreases below 450 psig.

a. To exceed Tech. Spec. limit of 100 F/hr,

pressure would have to decrease rapidly

from 1000psig to below 400psig, and

therefore outgassing could occor.

b. Opening SRVs without EHC system

compensation (MSIVs closed) is also rapid

depressurization (a condition that also

promotes outgassing).

d. industry experience indicates that notching

may occur- 450 psig and the ATC must be

alert.

mdication may occur as reactor pressure is lowered. A slow cooldown rate will decrease

the effect of degassing the reference leg.

1.30 if the Reference Leg Backfill System is not in service, then a reactor level bias could

develop from degassing of the level reference leg large enough to effect reactor level

1.31 Reactivity Controls During Reactor Shutdowns

'

All control rod insertions shall be done using the Shutdown Control Rod

j 1.

Sequence Package unless otherwise recommended by the on-duty reactor

engineer.

2. Reactor power should be reduced with core flow prior to control rod insertions to

minimize fuel duty.

3. If substitute values are entered into the process computer that affect thermal l

limits, the on-duty reactor engineer should update these values as necessary

during power reductions to ensure accurate thermal limit monitoring.

4. Prior to reducing power below the low power setpoint, the on-duty reactor

engineering should verify that all control rods are properly aligned per the BPWS

constraints.

5. The reactor should be scrammed from e power level at which normal pressure

control is available (i.e., turbine control valves open) to preclude inadvertent or

uncontrolled reactivity changes due to reactor cooldown and depressurization.

6. A reactor shutdown by manual control red insertion of all control rods shall not be

pennitted unless specifically authorized by the Operations Superintendent.
