3. Exit Meeting

a. On August 29, 1986, an exit meeting was held. The following personnel were present at this meeting:

K. Gerlinri, PWR Operations Training- Supervisor, Production Training Center R. E. Querio, Ryron Station Manager T. K. Higgins, Byren Training . Supervisor R. Pleniewicz,- Production Superintendent T. Petelle, Simulator Instructor, Production Training Center S. Shankman, Operator Licensing. Branch, NRC Headquarters F. Jaggar, INEL - Chief Examiner B. Picker, INEL Examiner

b. The following generic weaknesses of the candidates were discussed by the Chief Examiner with the utility:

(1) Difficulty finding procedural requirements for sampling when blowdown or air ejector monitors are 00S.

(2) Need to supply logic diagrams for control room personnel.

(3). Noted uncertainty in locating power supplies for NI channels.

(4) When a candidate asks a question of the reactor operator on -

watch, (with examiner's approval) the reactor operator should give a complete and accurate answer.

', ATTACHMENT BYRON SENIOR REACTOR FACILITY REVIEW COMMENTS QUESTION 5.15 Explain why a dropped control rod is worth approximately 200 pcm and a stuck cod is worth 1000 pcm even though the same rod could be considered '

in both cases. (Assume no trip.)

NRC answer:' When a rod is stuck out with all other rods inserted, the flux profile is higher where the rod is out, therefore, that rod " sees" a much higher flux than average core flux.

(Because rod worth is a function of the relative flux difference between the rod and the core average flux, the rod is worth more (about 1000 pcm). (1.0)

If a rod is dropped just the opposite happens. The rod depresses the the flux in the area near the rod relative to the average core flux. (Worth about 200 pcm). (1.0)

Comment: The question states " Assume no trip". The answer assumes a trip. Replace key with:

Rod worth is dependent upon the relative flux the rod sees.

With the rod stuck out it sees a high flux in comparison to a dropped rod, which would depress the flux in its vicinity.

Reference:

WCAP 10315 Nuclear Case Design Characteristic's RESOLUTION: ,

The original answer key is more detailed than the facility supplied answer because of the need to compare that answer with a number of varied responses expected from many candidates. Because of this situation,it remains as is. Full credit would be awarded for an answer such as provided by the facility comment above.

QUESTION 8.02

a. State the minimum number of gallons required per diesel to be in the Diesel Oil storage tanks and the associated indicated level (in %) for each Unit.

b. State the minimum number of gallons required to be in each unit's Diesel Generator Day Tank and the associated indicated level (in %).

NRC answerk a. 44,000 gallons Unit 1 - 93.8*4 Unit 2 - 90.0% (1.0)

Unit 2 - 80% (1.0)

CECO answer: a. 44,000 gallons (1.0)

b. 450 gallons (1.0)

Answer is as stated in Tech Specs. The percentages are not indicated on the Main Control Board. They appear only on the non-licensed operators round sheets. The round sheets have minimum levels stated on them. Should the actual level' (in %) reach the minimum, the non-licensed operator circles the reading in~ red pen and directs this reading to the attention of the Shift Supervisor.

QUESTION 4.01 -

The following concern operation of #1 Seal Bypass Valve (CV8142) on the Reactor Coolant Pupp.

a. If during performance of BOA-RCP-1 "RCP Seal Failure", and the #1 Seal Bypass Valve needs to be opened, what THREE conditions must exist before opening #1 Seal Bypass Valve (1.0]

NRC answer: a. 1. Seal Injection flow is 8-13 gym

2. #1 Seal Leakoff flow is < 1 gym

3. RCS pressure is < 1000psig CECO answer: IBOA RCP-1 has been revised, FOUR conditions must exist before the #1 Seal Bypass valve needs to be opened, therefore, any three of the four are acceptable.

a. 1. Seal Injection flow is between 8-13 gym

2. No. 1 Seal Leakoff isolation valves on open 3, No. 1 Seal Leakoff flow is less than 1 gym

a. During performance of BOA ROD-4, " Dropped Rod Recovery" prior to recovery of the dropped rod, state ALL methods that can be used to match Tref with Tave.

NRC answer: a. By reducing turbine load, diluting or moving rods CECO answer: Manually adjust rods

-OR-Manually adjust turbine load

-OR-Manually adjust RCS boron concentration

Reference:

IBOA ROD-4, pg. 2 Resolution:

The CE Co. answer further clarifies the NRC answer and no change to the answer key is necessary.

QUESTION 4.03

b. If a dropped rod cannot be recovered immediately, state the THREE conditions or actions, one of which is required to be completed within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months for power operator to continue.

NRC answer:, b. Within 1 hour:

1. Restore rod to operable status, (0.3]

2. Rod is declared inoperable (0.3] and other rods in group aligned within 112 steps, (0.3]

3. Rod is declared inoperable and

a. Tech Spec SDM satisfied,

b. Power reduced to < = 75%

CECO answer: The question is misleading by mentioning the one hour requirement. In addition, it does not restrict the examinee to Tech Spec. IBOA ROD-4 also supplies actions to be taken I

and should be included in the key.

1. Calculate the QPTR, if greater than 1.02, apply Tech Spec 3.2.4

2. Reduce power for dropped rod recovery.

3. Restore rod to operable status

4. Rod is declared inoperable and remainder of rods in ,

the group are aligned within i 12 steps of the inop.

rod while maintaining rod sequence and insertion limits.

5. Rod is declared inoperab,le and SDM is satisfice.

power operator may then continue provided that:

a) Power reduced to < = 75% within the next hour and within the following 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months the High Reactor Flux Trip Setpoint is reduced to less than or equal to l

85% of RTD b

Reference:

IBOA ROD-4, Rev. 51, pg. 3; Tech Spec 3.1.3.1 Resolution:

The question states that there are three actions to be completed within one hour. The Technical Specifications states these items are to be done within one hour and, therefore, is the basis for the answer. The items the facility desires, have no time limit associated with them for per-formance (according to procedure 180A R00-4).

However, because the question did not state " Technical Specifications",

the first answer " calculate the QPTR" will be accepted as one action.

l The second requested answer (power reduction) was in the original answer on the answer key.

a. As Unit 1 NSO, what constitutes "at the controls"?

b. Hot Spots.

NRC answer: b. Areas near equipment or piping where the DOSE RATE AT >

18 INCHES from the source EXCEEDS THE '

applicable posted i limits for the GENERAL AREA.

-OR- ,

Areas near equipment or pipes where the DOSE RATE AT 18 l

INCHES from the source would EXCEED 5 TIMES THE AMBIENT DOSE RATE for the GENERAL AREA. (0.75) l Ceco answer: b. Hot Spots:

l Areas near piping or equipment where the dose rate at 18" from the source exceeds five (5) times the ambient does rate for the area.

-OR-Areas near piping or equipment where the dose rate at- I less than 18" from the source exceeds the applicable posted limited for the area.

Clarification - CECO answer to Question 4.07 b. Hot Spots does not include

" General" area just area and talks about a dose rate at "Less Than 18" not l

" Greater Than".

a. (The excess inserts steam positive flow causes) reactivity Tave

[0.25]

(At the POAH), increased power will increase temperature which inserts negative reactivity via FTC. [0.25] Power will stabilize higher than the POAH [0.25] and Tave will lower than the no-load value (minus the number of degrees needed to overcome FTC). [0.25]

b. Power increase RATE is higher at EOL because of changes in Beta-Bar (MTC). [o S]

Final power is the same;Tave will be higher [0.5] (closer to no-load temperature) because of the different Beta-Bar (MTC) [0.5].

ANSWER 5.15 (2.00)

When a rod is stuck out with all other rods inserted, the flux e profile is higher where the rod is out, therefore, that rod "se's" a much higher flux than average core flux. (Because rod worth is a function of the relative flux difference between the rod and the core average flux, the rod is worth more (about 1000 pcm)). [1.0]

If a rod is dropped just the opposite happens. .The rod depresses the the flux in the area near the rod relative to the average core flux.

(Worth about 200 pcm). [1.0]
