Unit 1 is at 100% power with a stuck (not trippable) control rod.

Initiating Cues You are the Desk SRO and I am the Shift Manager. 1-OPT-RX-005, Control Rod Assembly Partial Movement, was conducted 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ago and control rod K-10 failed to move. I&C and Engineering have determined that the control rod is stuck mechanically and not trippable. Here is a copy of 1-OP-RX-001, Shutdown Margin (C alculated at Power). I need you to perform an At-Power Shutdown Margin calculation due to the stuck rod. You are performing this calculation as a ba ckup to the reactor engineering's calculation. A Curve Book will be provided. The following unit conditions exist:

o Core Burnup: 4500 MWD/MTU o Control Bank "D" height: 227 steps o Control rod K-10 is also at 227 steps.

o CB: 1100 ppm, measured 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months ago. No dilutions have taken place.

o T and PRNIS: 100% power When you finish the actions necessary to accomplish this, please inform me.

Initial Conditions:

1-VS-E-4D trips with 1-VS-E-4D and 1-VS-E-4C initially in service.

Initiating Cues

I am the Shift Manager and you are the Unit One US.

Dual chiller operations are in effect.

The third license operator identified that 1-VS-E-4D was no longer operating, as indica ted by the green light lit and red light out for the chiller unit. Local investigation revealed that a loss of control power to the chiller has occurred as all local LED lights are extinguished.

You are to determine whether an operable configuration/

combination exists, and required recovery actions in accordance with 0-OP-VS-006. Recovery actions s hall include any required chiller manipulations, if any.

When you have completed these actions, please inform me of your findings.

Surry 2009-301 RWP Compliance and Personnel Assignment G2.3.7 SR09301 2 of 12 None None Initiating Cues- Task 1 Task 1: Assume the following Initial Conditions:

1-BR-E-10A (Gas Stripper Steam Heaters) is to be tagged out and drained due to a suspected tube leak.

This task will take one Operator 22 minutes to complete, working the entire time in the vicinity of the heat exchanger.

All valves that will be manipulated or tagged are located in the immediate vicinity of the heat exchangers.

Included are copies of the Radiological Survey Map and an ALARA Component Locator Map for the area.

You are to determine:

1- Dose received by one operator to complete this task.

300mr (dose rate in area) X 22 min (time for task completion) X 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months hour 60 minutes

ANSWER- 110 mr

Surry 2009-301 RWP Compliance and Personnel Assignment G2.3.7 SR09301 3 of 12 Initiating Cues- Task 2 Task 2: Given the following set of operators:

Operator #1: Qualification Level = Step 4; Quarterly Dose = 1447 mrem Operator #2: Qualification Level = Stepped Out; Quarterly Dose = 1894 mrem Operator #3: Qualification Level = Step 6; Quarterly Dose = 1556 mrem Operator #4: Qualification Level = Step 7; Quarterly Dose = 1478 mrem (1) Assess each individual to determine wh ich individuals could be assigned to perform Task 1 based on qualification level and ensuring dose limits will not be exceeded.

Assume no dose upgrades will be authorized. Standard: Bolded & underlined text items are CRITICAL STEPS.

Operator #1:

CANNOT be assigned the task. The Operator is not qualified on that Watchstation. The Operator must have completed step 5 in order to per form tasks in the Auxiliary Building.

Operator #2:

CANNOT be assigned the task.

Either of the two responses are acceptable

1. The Operator is excluded from the RCA due to being >85% of the Quarterly Administrative Dose Limit of 2 rem/year (or greater than 1700 mrem).

VPAP 2101, Section 6.3.4, states - "If a worker's annual dose exceeds 85% of an administrative dose limit, t he worker will be denied RCA access until an upgrade is approved. 2. Operator would exceed admin limits (2.0 Rem/Yr). If task were performed, the additional 110 mr would put the operator over the 2.0 rem admin limit.

Operator #3:

CAN be assigned the task. The Operator is qualified on the Watchstation and their quarterly dose is below the administrative limit.

Operator #4:

CAN be assigned the task. The Operator is qualified on the Watchstation and their quarterly dose is below the administrative limit.

(Reference 2.3.7)4.12Changing the Chilled Water flow to a MCR or ESGR AHU will change the Chilled Water flow to all AHUs on the associated Chilled Water Loop.4.13When Chilled Water flow to any AHU is changed, acceptable Chilled Water flow must be verified to all AHUs on the associated Chilled Water Loop IAW Attachment5 or Attachment6 as applicable.4.14AHUs should be placed in service on a Chilled Water Loop before starting a chiller on the same loop.4.15Attachment5 or Attachment6 may be used independently at any time to determine the existence of acceptable Chilled Water Flow to the MCR/ESGR AHUs.4.16To prevent an excessively negative pressure in the Main Control Room and possible damage to the MCR pressure boundary, 1-VS-AC-4 must be running before 1-VS-F-15 is started.4.17The MER 3 Chiller Trouble annunciator will alarm if any MER 3 Chiller Compressor is not started within nine minutes of starting the respective Chilled Water and Service Water pumps.Mark NumberArea ServedMinimum Flow1-VS-AC-1Unit 1 MCR10 gpm1-VS-AC-2Unit 1 MCR10 gpm1-VS-AC-6Unit 1 ESGR85 gpm1-VS-AC-7Unit 1 ESGR85 gpm2-VS-AC-6Unit 2 ESGR85 gpm2-VS-AC-7Unit 2 ESGR85 gpm2-VS-AC-8Unit 2 MCR20 gpm2-VS-AC-9Unit 2 MCR20 gpm DOMINION0-OP-VS-006Surry Power Station Revision 55Page 11 of 1194.18In the tables contained in this procedure which contain Required Actions for chiller inoperability, the Control Room Chillers will be referred to by the letters "A" through "E". The "1-VS-E-4" part of the chiller mark number is to be understood.4.19Attachment1 contains tables that identify which 4160 Volt Emergency Bus serves as the Normal (and Alternate where applicable) power source for each Control Room Chiller and those combinations of operable Control Room Chillers which will satisfy Technical Specification 3.23.4.20Subsections 5.28 through 5.32 provide the major steps for ensuring continued compliance with Tech Spec 3.23. Individual component manipulations are to be performed IAW referenced subsections and/or procedures.4.21The words "Operable Combination" as used in this procedure are defined to mean a group of operable chillers which together satisfy the requirements of Technical Specification 3.23 so that entry in to a Technical Specification clock is not required.4.22Attachment1 may be used independently at any time to determine the existence of an Operable Combination of Control Room Chillers.4.23Allowable single chiller operation alignments are as follows:Loop A Chiller A or Chiller D or Chiller ELoop CChiller A or Chiller B or Chiller CAlignment of 1-VS-E-4B on Loop A and alignment of 1-VS-E-4D or 1VS-E-4E on Loop C are provided as a contingency alignment for the Chilled Water Piping Replacement Project. 4.24Subsection references are included for guidance when manipulations are required to achieve the desired alignment and do not need to be performed to verify condition(s) that exist from prior procedural performance.4.25If any parameter in Attachment4, MER 3 Chiller Operating Checks is exceeded, the HVAC Crew will be required to perform 0-MPM-0210-01, Control Room Chillers Performance Checks to determine chiller operability.
