MEMORANDUM TO: Exam File PPL Susquehanna, LLC Susquehanna Steam Electric Station DATE: July 23, 2002 tS 37 /?3/?.

FROM: Alan Blarney Senior Operations Engineer

SUBJECT:

COMMENTS ON SUSQUEHANNA STEAM ELECTRIC STATION UNITS 1 & 2 EXAM - Pre and Post VALIDATION.

The purpose of this memorandum is to document comments on the Susquehanna exam received on Thursday June 20, 2002. (Note: the exam review was completed in 13 working days instead of 10 due to availability of reviewers - Pilgrim Prep. Week) The written exam was reviewed by A. Blamey, Senior Operations Engineer and C. Sisco, Operations Engineer. The operating exam was reviewed in its entirety by A. Blarney, with portions of the operating exam reviewed by C. Sisco. The comments were provided to R. Chin Examination Developer, Susquehanna during the prep week, July 14, 2002. The comments are as follows.

ES-401-7 Written Examination Quality Checklist do See ES 401-9, "Written Exam Review Worksheet," for comments.

_ _ The Reactor Recirculation System speed control logic is overweighted.

Question 41 for RO I SRO has been changed to focus only on the feedwater heaters.

dt Verify the method that was used to ensure no overlap between the audit and written exam.

ES-301-3 Operating Test Quality Checklist Cat. A Admin Section General Comments

>z Very that the JPMs have the required reviews as per the PPL program.

Direct "look up" question can be asked but they must be closed reference questions. ES-301, Attachment 1 provides guidance on what constitutes a look up and what is not a look up. However, ES-301-3, item 2.b, states that Category A are predominantly open refernce.

Senior Reactor Operator Administrative JPM Comments

_ SRO, A.1.a, This question is a direct look up. Additionally, would you expect your SRO to know that the individual should not

take the shift when he is on Codeine or would an MD make this determination? There is no procedural guidance on this issue.

This was changed to the individual failing his eye exam and not being able to obtain glasses prior to assuming licensing duties. The SRO applicant must now understand license restrictions and actions that must be taken. There is procedure guidance on this issue.

SRO, A.1.b, This question is a direct look up.

The stem was changed to a unit supervisor instead of a shift supervisor to allow notification of the shift supervisor.

The answer was changed to be more realistic and encompasses important actions in procedure ON-155-001, step 3.6 as well as the original answer in procedure OP-AD-002.

SRO, A.1.c, This question is a direct look up.

The question was changed to require the applicant to determine the minimum shift staffing requirements and then take appropriate actions.

SRO, A. I .d, Day shift hours should be listed for accuracy.

No change needed, accept as is.

SRO, A.2 The K/A for this JPM is 2.2.24, which is effect maintenance has on equipment LCOs. The question is on a failed surveillance. The outline was approved on surveillance procedures and the K/A for surveillance is more significant.

Change the K/A number to the correct one 2.2.12.

Why does this JPM have to be performed in the simulator?

This JPM will not be performed in the simulator.

SRO, A.3.a No comments SRO, A.3.b This question is a direct look up.

Question is changed to require a calculation to determine dose rate and then take appropriate actions in accordance with station procedures and TS.

a SRO, A.4 The JPM says that this can be performed at the completion of a scenario for the US. During this exam it can not be performed in this manor because it would be repeated on different days.

_ _ This JPM is time critical and should be less than 15 minutes.

_ _ Is this the responsibility of theeor RO?

PPL - this is the responsibility of the SRO. However, there were several items that were incorrect in the JPM.

-to The JPM must have the PICSY weather conditions.

-(ii) The JPM must be updated for current job requirements, i.e., delete the step 4 and the associated critical task.

4lii) Provide a completed ENR form.

Reactor Operator Administrative JPM Comments RO, A.1.a, No Comments RO, A.1.b, This is a direct look up.

The stem question (a) was changed from position discrepancy to condition. The operator must now identify the misspositioned control rod based on the information in the stem.

I; RO, A.1.c This is a direct look up. The wording temporary relief gives the answer away and makes direct look up.

The question was modified so that the person would report off site for a random drug test. He must understand that the testing is off site and since he is leaving the control structure he must perform a short term relief turn over.

_ RO, A.1.d This is a direct look up, the question can be reword to give answer, and K/A match not adequate.

This question has been change. The individual will receive an incomplete procedure and must determine what actions have to be taken to obtain a new 'good" procedure.

RO, A.2, No Comments

RO, A.3.a, No Comments RO, A.3.b This is a direct look up.

The stem of the question will now require the applicants to determine (calculate) dose rate and then determine what approvals I controls are required.

RO, A.4.a This is a direct look up question and this was asked on the written exam.

The question will be replaced with a simplex fire alarm.

The applicant must take the alarm, find the area, and then determine action based on a fire in that area.

___ RO, A.4.b The outline states ALERT the question states UNUSUAL EVENT. Change the question to an ALERT to match sample plan.

Cat. B Job Performance Measures (JPM)

B.1.a Step 19 should be a critical step.

___ B.1 .c Bypassing SRM channel "C" Rod Block Input to RMC.

This JPM was modified to remove the control rod withdrawal at the beginning of the JPM. This activity provided addition time and set up that did not effect the required action of the JPM.

___ B.1.d Is this JPM a direct bank JPM or modified and if modified then what is the date / rev. on the JPM. -

B.1.e Step 7 should have the instrument air cross-tie valves listed as 126172 and 126167.

B.2.a Fire Protection System Crosstie to RHRSW.

This JPM was changed during validation week from Fire Protection System Crosstie to RHRSW,,to Connecting the Standby Liquid Control Tank to the RCIC System in accordance with ES-150-002. The basis for this change was to increase the discrimination ability of the JPM portion of the exam and minimize dose.

ES-301-4 Simulator Scenario Quality Checklist General Comments Very that the scenarios have the required reviews as per the PPL program. The original scenarios that were sent with the approved exam was not approved by the supervising manager, as required.

Verify that the simulator modeling is not altered for the exam.

Review the simulator scenarios that were used for remediation during the prep. week and determine if there any adjustment must be made to the NRC exam scenarios.

Scenarios NRC0201 Page 21, The power decrease may be less than 20%.

___ NRC0202 Page 16, The power decrease may be less than 100 MWe.

Page 22, The scenario should provide the information that both CRD pumps are damaged beyond repair so that we will not have to wait 20 minutes to shutdown.

Review the level of difficulty at the simulator. This scenario has 4 failures after the EOP entry conditions which are required to get the plant to an emergency depressurization state.

The insertion of control rods should not be a critical task because the actions are taken locally. This will remain a CT because the actions are directed by the applicant and in accordance with Appendix D, D. 1. a, effectively directing can be considered a CT.

NRC0203 Page 7, Why is identifying that the RPV level indication is no longer valid a Critical task. If they do flooding don't they recognize this? - JOT C-T.

L NRC0204 Page 20, why isn't inhibiting ADS a critical task and why isn't there a step to run recircs back to minimum and trip one at a time?

ADS not critical in this scenario and Recirc pumps will be tripped due to EXC RPT.

Page 24, first step, PCOM should be a critical step, manual rod insertion. This is a continuation of a critical task from the previous page.

Page 25, instructor activity 1 & 2, should these activities be based on the actual time to perform the activity. For example, activity 1 will take about 15 minutes, not five.

NRC0205 None

ANS The was corrected to state the minimum water level.

SROs will have EOP 113, therefore, this question is a direct look up and not acceptable for a memory level question.

ANS To determine the water level the applicant will have to work through the EOP or know from memory based on high power to find answer. Not direct look up.

The answer agrees with the procedure but I do not technically understand why you would not raise level to promote natural circulation?

ANS This answer is technical correct because if level was increased to enhance natural circ. the J-Tube and stub tube welds would see a rapid temperature change /

increase in thermal stress.

[Refer to Section D of ES-401 and Appendix B for additional information regarding each of the following concepts.]

1. Enter the level of knowledge (LOK) of each question as either (F)undamental or (H)igher cognitive level.
2. Enter the level of difficulty (LOD) of each question using a 1 - 5 (easy - difficult) rating scale (questions in the 2 - 4 range are acceptable).
3. Check the appropriate box if a psychometric flaw is identified:
  • The stem lacks sufficient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).
  • The stem or distractors contain cues (i.e., clues, specific determiners, phrasing, length, etc).

The answer choices are a collection of unrelated true/false statements.

More than one distractor is not credible.

One or more distractors is (are) partially correct (e.g., if the applicant can make unstated assumptions that are not contradicted by stem).

4. Check the appropriate box if a job content error is identified:

The question is not linked to the job requirements (i.e., the question has a valid K/A but, as written, is not operational in content).

  • The question requires the recall of knowledge that is too specific for the closed reference test mode (i.e., it is not required to be known from memory).

The question contains data with an unrealistic level of accuracy or inconsistent units (e.g., panel meter in percent with question in gallons).

  • The question requires reverse logic or application compared to the job requirements.
5. Check questions that are sampled for conformance with the approved K/A and those that are designated SRO-onl, (K/A and license level mismatches are unacceptable).
6. Based on the reviewers judgment, is the question as written (U)nacceptable (requiring repair or replacement), in need of (E)ditorial enhancement, or (S)atisfactory?
7. At a minimum, explain any "U"ratings (e.g., how the Appendix B psychometric attributes are not being met).

B14 F 2 Y S N B15 F 2 Y S M B16 H 2 Y S B Ventilation recirculation system reduces the dose but if it failed I l the off site dose is expected to rise but not exceed 10 CFR 100.

B17 F 2 Y U M Isspecifically there a correct answer? The answers & distractors state "only," and do not address the ECCS room cooler (safety related loads). Based on your plant configuration both ESW loops will automatically supply the Room Coolers.

(C)- A CR on the core periphery will not be stopped by the RBM nor will it provide a scram, unless specific conditions exist.

Provide more specifics - rod location.

(d) - control rods do not drop from 24 to 00 they drop from 00 to 24.

ANS Stem focus was improved and distractors were corrected.

B39 F 2 Y S M Based on your JTA is this expected to be know from memory.

(Hot box - have all personnel read the hot box or have the license applicants procedures been froze before the hot box was issued?)

ANS Yes they have been trained and expect to know from memory B40 F 2 Y S B EOP 113 (sheet 1&2?) will be provided to the applicants. This changes the question to a simple lookup. This is not acceptable for a memory question.

ANS Sheet will NOT be provided B41 H 3 Y E N The question answer is correct but for the wrong reason. The Hi-Hi alarm will not result in an isolation. Level will continue to rise until 47 is reached and then a 30 second time delay to isolate. Not a 30 second time delay after the 35' Hi-Hi alarm. So the actual isolation will occur when the heater fills up to 47" and a 30 second time delay - hence after 30 seconds is correct.

B42 H 1 X X Y U N The correct answer is the only answer/distractor that contains the fuel pool cooling and cleanup system, same as the stem. In addition, (C) Is also correct because of water level decreases to this level the fuel pool cooling pumps / system will trip.
