HLT 9208 written examination post examination comments RO question 01;SRO question 01 Question: The reactor is being restarted near the end of core life following a one day outage.Reactor power is at 32%.Control rods 34-23 and 58-23 have been isolated at position 00.When rod 42-43 is withdrawn, alarm 2-XA-55-5A-29, CRD ACCUM PRESS LOW LEVEL HIGH, actuates on panel 9-5.WHICH ONE (1)of the following requirements is in effect under current plant con ditionsV a.Exercise control rod 42-43 at least one notch at least once each day.b.Clear the accumulator trouble alarm on rod 42-43 prior to moving to the next control rod.c.Control rod 42-43 must be fully inserted and electrically disarmed.d.Observe nuclear instrumentation for response each time rod 42-43 is moved.Answer key answer: D Comment: For any event that can directly affect reactivity, it is considered to be of a critical nature and strict procedural compliance along with conservative actions must be followed.This caution is prevalent throughout BFNP procedures such as: SSP 12.17 2-0I-85 2-GOI 100-1A 2-Gol 100-1B 2-GOI 100-1C Reactivity Management, page 9 Control Rod Drive system Precaution and Limitations 3.1.13, page 8, 10, 11[INPO SOER 84-002]Unit Startup From Cold Conditions section 3.12 page 12[INPO SOER 89-006, SOER 88-002]Unit Startup From Cold Shutdown to Hot Standby section 3.11 page 12;[INPO SOER 89-006, SOER 88-002]Unit Startup from Hot Standby page 9 section 3.10.[INPO SOER 89-006, SOER 88-002]During the situation described in the stem of this question, rod 42-43 is potentially inoperable if the accumulator alarm is valid.This would make answer B also correct since during a reactor startup, it would be assumed that the next control rod movement would be a rod withdrawal, it would not be conservative action to continue rod withdrawal with an potentially inoperable rod that is not fully inserted.Additionally, the alarm response procedure directs dispatching of personnel to determine if the alarm is valid and directs the use of 2-Ol-85 to clear the alarm.This would be the expected course of action should this event occur in the plant.Answer D is correct because this requirement is in place per Technical Specifications whether the rod is being inserted or withdrawn.

I Proposed resolution:

Accept either B or D as a correct answer

HLT 9208 written examination post examination comments RO question¹57;SRO question¹47 Question: WHICH ONE (1)of the following is an acceptable way to perform position verification on a throttled valve?(assume that the valve is installed in a system with local indication controlled by the valve, and the valve has a rising stem)a.observe the initial valve operator's action in positioning the throttled valve b.perform an independent visual check of the valve position by observing the valve stem c.independently verify the valve position by a second valve operation d.by observing flow indication through the throttled valve's system Answer key answer: A Comment: SSP 12.6 (Verification program)page 7, states that throttled valves are normally verified using second party verification.

However, section 3.3.3 (also on page 7)states that alternate verification methods may be used at the discretion of shift supervisory personnel.

One of these alternate verification techniques is the use of process parameters.

Since the question stem asks for thief lygp D is also correct.Proposed resolution:

Accept either A or D as the correct answer HLT 920B written examination post examination comments RO question 061;SRO question 053 Question: Four licensed UOs attended a fellow employee's birthday party the last night of their vacation and alcohol was served to all.Below shows when each UO stopped drinking alcoholic beverages.

UO A1:05 am UO B2:05 am UO C 3:05 am UO D 4:05 am From the four UOs listed above, WHICH ONE (1)of the following states the number available for NRC licensed work the same morning at 7:00 am?(Assume that all the UOs have blood alcohol levels within SSP 1.6 guidelines) a.ONE b.TWO c.THREE d.FOUR Answer key answer: B Comment: SSP 1.6 (Fitness for duty)states on page 6, section 3.1.4 that a person covered by the scope of the procedure shall abstain from the consumption of alcohol for at least 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months preceding any scheduled work.Therefore, to be available for work at 7:00 am, an individual would have to stop drinking prior to 2:00 am.Since only UO A had stopped drinking prior to 2:00 am, he or she would be the only one available to work at 7:00 am.Answer B is not correct.Proposed resolution:

Accept A as the correct answer

HLT 9208 written examination post examination comments SRO question¹62 Question: The control room was evacuated due to a fire 5 minutes ago.Atl the immediate actions for"Control Room Abandonment" were performed.

Current plant conditions are: The reactor has been verified to be shutdown.RPV level is>+60 inches.RPY pressure is 700 psig and decreasing slowly.The MSIVs are open and cannot be closed, The turbine bypass valves appear to functioning normally.An operator is stationed to control RPY level and pressure with HPCI as necessary WHICH ONE (1)of the following is the appropriate emergency action level for this situation?

a.Unusual Event b.Alert c.Site Area Emergency d.General Emergency Answer key answer: C Comment: The stem of the question states that the control room was evacuated due to a fire, but does not state the location of the fire.Due to the proximity of some offices to the control room, it is conceivable that a fire in those offices could result in enough smoke in the control room to warrant evacuation without an actual fire in the control room.With this limited information, it is merely a judgment call by the SOS as to whether the fire is in i I (alert)or actually ff i vi I r (site area emergency).

Additionally some of the information given in the stem is confusing:

(1)HPCI is being used to control level and pressure, but in 2-AOI-100-2, step 4.2.10, HPCI would be disabled (2)The MSIVs are stuck open, reactor pressure is dropping, but the bypass valves are functioning normally.There is no available indication of bypass valve position at the backup control panel.The pressure decrease could be considered to be normal (depending on recent power history)with reactor water level at+60 and normal auxiliary steam loads in service and without supporting indications (radiation or temperature alarms, or reports from the plant)the slow pressure decrease would not necessarily be indicative of a leak during the first 5 minutes of the event.With no data on radiation levels in the plant or coolant activity levels, reference to the general descriptions of the emergency classifications on pages 1 and 2 of EPIP-1 could lead to alert as the appropriate classification.

Proposed resolution:

Accept either B or C as the correct answer HLT 9208 written examination post examination comments RO question¹97;SRO question¹96 Question: RHR loop I is in shutdown cooling taking suction through Shutdown Cooling suction valves 74<7 and 74-48.Loop II of RHR remains in the LPCI standby lineup.Due to misoperation of ventilation systems, drywell pressure increases to 2.5 psig.WHICH ONE (1)of the following describes the response of the RHR system?a.Valves 74-47 and 74-48 close, Loop I suppression pool suction valves auto and BOTH RHR loops inject to the vessel.b.Valves 74-47 and 74-48 close, Loop I RHR pumps trip, suppression pool suction valves auto open but only Loop II injects.c.Valves 74-47 and 74-48 close, Loop I RHR pumps trip, Loop I suppression suction valves remain closed and only Loop II injects.d.Valves 74-47 and 74-48 close, Loop I RHR pump trip, Loop I suppression pool suction valves remain closed and NEITHER Loop injects.Answer key answer: C Comment: 2-0I-74 page 69 of 202, and Lesson Plan OPL171.044 page 24 states the actions that occur on a group 2 isolation when the RHR system is operating in the shutdown cooling mode.On the isolation signal, both of the Loop I and II inboard injection valves would receive a close signaI and would not automatically reopen until the group 2 isolation signal was reset on panel 9-3.Therefore, neither loop of RHR would inject without some form of operator manual action.Since this action was not listed in the stem of the question, answer C could not be correct.Proposed resolution:

Accept D as the correct answer 0 0 ENCLOSURE 4 RESOLUTION OF FACILITY COMMENTS ON WRITTEN EXAM 1.SRO Question 1 (RO Question 1)Facility comment accepted.2.SRO Question 47 (RO Question 57)Facility comment accepted.3.SRO Question 53 (RO Question 61)Facility comment accepted.4.SRO Question 62 (No RO question)Facility comment accepted.5.SRO Question 96 (RO Question 97)Facility comment accepted.

BROWNS FERRY NUCLEAR PLANT EMERGENCY PLAN IMPLEMENTING PROCEDURE El'Il'-1 EMERGENCY PLAN CLASSIFICATION LOGIC RKSIQN 13 PREPARED BY T.W CORNELIUS PHONE: 2038 RESPONSIBLE ORGANIZATION:

EMERGENCY PREPAREDNESS APPROVED BY: T W.CORNELIUS DATE: 07/01/92 EFFECTIVE DATE: OZ/09/92 VALIDATION DATE: NOT REQUIRED QUALITY-RELATED Procedure Number: EPIP-1 i.Pages.Affected: 15 Pagination Pages: NONE Description of Change: REVISION LOG Revision Number: 13.Change phone 0 from 236-1500 to 273-8500.

EMERGENCY CLASSIFICATION LOGIC 1.0 PURPOSE 1.1 To provide guidance to the Shift Operations Supervisor (SOS)or Site Emergency Director (SED)on what constitute's an emergency classification.

'1.2 To ensure that the emergency classification is consistent with that used by the local and state governments and the NRC.1.3 To provide a cross reference between this procedure and the ONP-REP, Appendix A, for use by the SOS or SED for additional information in'classifying events.2.0 SCOPE 2.1 This procedure applies to those events, that in the professional judgment of the SOS or the SED constitutes an emergency.

The SOS and the SED are the only individuals authorized to make the emergency class determination.

2.2 The events listed in the attachments to this procedure cannot possibly incorporate all events which can occur.Therefore, all classifications should be judged against the general guidance listed below: 2.2.1 Notification of Unusual Event Unusual events are in process or have occurred which indicate a potential degradation of the level of safety of the plant.No releases of radioactive material requiring offsite response or monitoring are expected unless further degradation of safety systems occurs.2.2.2 Alert Events are in process or have occurred which involve an actual or potential substantial degradation of the level of safety of the plant.Any releases are expected to be limited to small fractions of the EPA Protective Action Guideline exposure levels.0300p i

2.0 (Continued)

REV 00 ZS Page 2 BFN-EPIP-1 2.2'.3 Site.Area Emergency Events are in process or have occurred which involve actual rotection of the ublic.Any releases are not, expected to exceed EPA Protective Action Guideline exposure levels except near site boundary-2.2e4 General'Emergency Events are in process or have occurred vhich invoive actual or imminent'suhstantial core de radation or meltin vith pbtential for loss of-containment inte rit.Releases can be reasonably expected to exceed EPA Protective Action Guideline exposure levels offsite for more than the immediate site area.3 0 INSTRUCTION 3.1 Review Attachment 1'to determine if an event should be classified as an emergency.

Note: (1)If an emergency action level for a higher classification was exceeded, but the present situation indicates a lower classification, the fact that the higher classification occurred shall be reported to the NRC and the CECC (if staffed), but should not be declared.(2)If an emergency action level was met but the emergency has been totally resolved, the emergency class that was appropriate shall be declared and terminated at the same time.s 3.1.1 Attachment 1 captures events in four br'oad categories:

Fission Product Barrier Degradation (F)System Malfunction (S)Radiation Levels Abnormal/Radiological Effluents (R)Hazards and Other Conditions Affecting Plant Safety (H)3.1.2 Each actual condition in a category is given an alphanumeric designator (FU1=Fission Product Barrier Degradation (F)resulting in Notification of Unusual Event (U)01).3.1.3 The only significance of the alphanumeric designator is a cross-reference to ONP-REP, Appendix A, which provides additional information for the SOS/SED in classifying the event.0300p 3.0 (Continued) 3.2 If the event is determined to be one of the four emergency classification, the SOS assumes the responsibilities of SED.3.2.1 Implement one of the following procedures as applicable:

EPZP-2-Notification of Unusual Event EPIP-3-Alert EPIP-4-Site Area Emergency EPPP-5-General Emergency 3.2N2 Continue to review the emergency conditions in Attachment 1 to escalate, de-escalate or terminate the emergency as appropriate.

3.3 If the event is determined not to be one of the four emergency classifications, continue to monitor plant conditions.
