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 perform 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 workers annual dose exceeds 85% of an administrative dose limit, the 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.

You are the Nuclear Shift Manager. An event is in progress with plant conditions as follows:

The station has experienced a loss of offsite power due to grid collapse. The system operator reports 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> for power restoration to Surrys switchyard.

Both units are currently at Hot Shutdown.

When attempting to load the AAC diesel on the 1J bus, the 1J bus faulted and electricians have determined that extensive damage has occurred to the buswork with repairs estimated to take 4 days.

_______ 3.1 The Control Room and Relay Room Ventilation System has been aligned IAW procedure 0-OP-VS-006A.

4.0 PRECAUTIONS AND LIMITATIONS 4.1 Chillers must be operated with Chilled Water Loop A and Loop C aligned as separate loops.

4.2 Power must be supplied to an MER 3 chiller for a minimum of 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and to an MER 5 chiller for a minimum of 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> before the chiller is started. This ensures adequate crankcase heating which removes freon from the oil.

4.3 The Control Room Chillers will not start when the temperature of the chilled water returning to the chiller is less than the chiller thermostat setpoint.

4.4 The following thermostat setting limitations apply for all MER 3 Control Room Chiller starts. (Reference 2.4.1) 4.4.1 Adjusting the Chilled Water thermostat requires manipulating controls inside an energized electrical panel. Use of a non-conductive screwdriver (kept in the non-SQC storage locker in the MCR Annex) is recommended.

4.4.2 Before starting the chiller, the Chilled Water thermostat must be set to 65°F.

4.4.3 Following chiller start, the thermostat should be decreased to 45°F in 5°F (or smaller) steps, allowing time for the chilled water temperature to stabilize between steps.

4.4.4 When the chiller is operating in a stable condition with the thermostat at 45°F, the thermostat will be adjusted as required to obtain 40°F to 45°F AHU inlet temperature on the respective chilled water loop.

DOMINION 0-OP-VS-006 Surry Power Station Revision 55 Page 9 of 119 4.5 The MER 3 chillers strainer backwash valves (1-SW-317, 1-SW-327, or 2-SW-337),

are open when the arrow or scribe mark on the respective valves stem is in line with the Service Water piping and closed when the arrow or scribe mark is perpendicular to the Service Water piping. (Reference 2.4.1) 4.6 To ensure an adequate heat sink for the MER 3 chiller condensers and prevent possibly lifting a chiller freon relief valve when an MER 3 chiller is started, the respective strainer backwash valve must not be throttled any more than is required to obtain at least 30 psig discharge pressure on the associated Chiller Condenser Service Water Pump.

4.7 To prevent lifting the freon relief valve for the MER 3 chiller condensers, MER 3 Control Room Chiller compressors shall not be started and the MCR switch for any MER 3 Control Room Chiller being aligned for startup must be placed in OFF if Service Water temperature at the chiller inlet exceeds 100°F.

4.8 AHU 1-VS-AC-220, MER 3 Air Handling Unit, shall not be aligned to both Chilled Water loops at the same time. In order to ensure cooling is maintained to MER 3, AHU 1-VS-AC-220 should remain aligned to Chilled Water Loop C when any MER 3 Chiller is operating unless otherwise directed by an approved procedure.

4.9 Chiller 1-VS-E-4A will normally be aligned in a standby mode for Chilled Water Loop C and aligned to the Normal feeder (1J). Operation of 1-VS-E-4A on Chilled Water Loop A requires re-alignment to Loop A IAW Subsection 5.18.

4.10 To prevent possible overloading of an Emergency Bus, only one chiller at a time may be operating on any one Emergency Bus.

DOMINION 0-OP-VS-006 Surry Power Station Revision 55 Page 10 of 119 4.11 Minimum Chilled Water flows for the Control Room / ESGR AHUs are listed in the table below. (Reference 2.3.7)

Mark Number Area Served Minimum Flow 1-VS-AC-1 Unit 1 MCR 10 gpm 1-VS-AC-2 Unit 1 MCR 10 gpm 1-VS-AC-6 Unit 1 ESGR 85 gpm 1-VS-AC-7 Unit 1 ESGR 85 gpm 2-VS-AC-6 Unit 2 ESGR 85 gpm 2-VS-AC-7 Unit 2 ESGR 85 gpm 2-VS-AC-8 Unit 2 MCR 20 gpm 2-VS-AC-9 Unit 2 MCR 20 gpm 4.12 Changing 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.

4.13 When 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 Attachment 5 or Attachment 6 as applicable.

4.14 AHUs should be placed in service on a Chilled Water Loop before starting a chiller on the same loop.

4.15 Attachment 5 or Attachment 6 may be used independently at any time to determine the existence of acceptable Chilled Water Flow to the MCR/ESGR AHUs.

4.16 To 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.

4.17 The 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.

DOMINION 0-OP-VS-006 Surry Power Station Revision 55 Page 11 of 119 4.18 In 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.

4.19 Attachment 1 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.

4.20 Subsections 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.

4.21 The 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.

4.22 Attachment 1 may be used independently at any time to determine the existence of an Operable Combination of Control Room Chillers.

4.23 Allowable single chiller operation alignments are as follows:

Loop A Chiller A or Chiller D or Chiller E Loop C Chiller A or Chiller B or Chiller C Alignment 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.

4.24 Subsection 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.

4.25 If any parameter in Attachment 4, 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.
