?ERFORi~iED BY 3.1 3~2 3.3 If reactor vessel head is to be unbolted, verify Keff less than or equal to 0.95 and Tavg less than or equal to 140'F.Zf in cold snutdown, verify Keff less than 0.99 and Tavg less than or equal to 200'F.The Residual Heat Removal System is in operation, maintaining reactor coolant system temperature.
The reactor coolant drain tank and a minimum of one o the drain tank pumps is operable.The discharge of the reactor coolant drain tank pump is 1'ned up to selected CVCS HUT tanks through CS-460.Page 1 of 6 Rev.2 P ERFORMED BY 3'There is sufficient capacity in the CVCS holdup tanks to receive coolant released from the Reactor Coolant System when the pressurizer and the reactor vessel head are drained.3.5 3.6 The pressurizer backup and variable heater breakers must be tagged open.The pressurizer is open to the pressurizer relief tank through a power operated relief valve.3.7 A nitrogen blanket of 5 psig is being maintained in the pressurizer from the pressurizer relief tank through the relief valve discharge line.3.8 A temporary tygon hose is connected to valve 2-RC-116-L3 for level indication.
The tygon hose is looped so the top of the loop is at least ten (10)feet above the intended level indication desired and attached to manual vent 2-WD-238 on the pressur'zer rel'ef tanks The blank lange on the PRT vent (2-WD-238) requires being replaced by a flange with a piping tee on't with temporary valves on the two (2)free ends.One end is to connect to the level tygon hose.The other is to be connected to a tygon hose that is routed to the instrument room purge exhaust suction valve.Ensure there are no loop seals or kinks in the tygon hose to be used or level indication.
3.9 Pressurizer
level is in the indicating range or filled solid.3.10 The reactor head vent is connected to the pressurizer relief tank via installed vent spool piece.3.11 Shut and tag shut primary water to boric acid blender 12-PW-263.
~Terify CLOSED and hang a clearance on primary water to chemical mix'g tank 2-PW-256 and primary water flush to emergencv boration line 2-PW-265.This helps to avoid an inadvertent dilution while at half loop.3.12 If a tygon hose is to be used for level indication, the closed circuit television monitor mus be connected and funtioning properly.Page 2 of 6 Rev.2

4.0 PRECAUTIONS
4.1 4.2 The applicable Radiation Protection procedures for handling radioactive liquids and for venting vapors and gasses must be observed.The water level in the reactor vessel must be below the vessel flange before the head is unbolted for removal.The reactor flange elevation is 621 feet, 14 inches.The elevation of 4 loop is 614 feet, 0 inches.For RCP seal work and/or steam generator manway removal, the level must be brought to the center line of the hot and cold legs.This is commonly referred to as half loop.The level should be at half loop for a peri-od of eight hours after the PRT and tygon level instru-mentation is vented to atmosphere before allowing man-ways to be removed.4.3 4.4 4.5 The pressurizer relief tank level must be reduced to less than 5%to allow nitrogen flow to the pressurizer through the open power operated relief valve.Maintain reactor coolant system temperature greater than 60'F to ensure the reactor head temperature remains greater than 60'F until tension is relieved from the reactor head studs per Westinghouse refueling procedure.
Do not drain Reactor Coolant System below center line of the loops (614'")when nuclear fuel is in the vessel or while on RHR.4.6 Anytime draining of the RCS is in progress, careful observation of the RHR System is recuired.The pump amperage is the firs" indication o cavitation or loss of suction.5.0 DATA/SIGNOFF SHEETS 5.1 Data/Signof Sheet 5.1, Draining Reactor Coolan Valve Lineup.6.0 INSTRUCTIONS PERFORMED BY 6.1 6.2 Complete the attached Data/Signoff Sheet 5.1, Draining Peactor Coolant Valve Lineup.Start low p essure letdown from the Reactor Coolant System via the Residual Heat Removal System following 2-OHP 4021.017.002, Placing In Service and Operation of Residual Heat Removal Loop.Page 3 of 6 Rev.2
~I~~2-OHP 4021.002.005 P ERZORMED BY 6.3 Monitor pressurizer relief tank pressure while draining the system.Maintain a positive nitrogen pressure not to exceed 5 psig.6.4 6.5 Close reactor coolant drain tank vents to vent header 2-DCR-201 and 2-DCR-203.
This is to prevent getting water into vent header when draining Reactor Coolant System.Open loop drain isolation valves 2-RC-113-L1, 2-RC-113-L2, 2-RC-113-L3, and 2-RC-113-L4.
6.6 Loop drains flushing-These steps are to be done in sequence so the loop drains are flushed clean of crud.Open the drain valves wide to allow full flow to the reactor coolant drain tank.Valve off if necessary to control reactor coolant drain tank level and then reopen to obtain the required flushing time.6..6.1 , Open 2-RC-114-L'nd allow full flow for a minimum of two (2)minutes.6.6.2 Open 2-RC-114-L4 and allow full flow for a minimum of three (3)minutes.6.6.3 Open 2-RC-1'4-L2 and allow full flow for'minimum of two (2)minutes.6.6.4 Open 2-RC-114-L3 and allow full flow for a minimum of three (3)minutes.6.7 After completion of ste'p 6.6, the our (4)loop drains should be used as system drains.These drains and the low pressure letdown of step 6.2 o this procedure can be used in any combination to control the drainage from the system.NCTE When using loop drains, station an operator at the Waste Disposal System panel to observe reactor coolant dra'n tank level so that drainage can be controlled to prevent flooding the reactor coolant drain tank.Page 4 of 6 Rev.2 2-OHP 4021.002.005 PERFORMED BY 6.8 When pressurizer level is reduced to 5%indicated, open the reactor head vent valves 2-RC-132 and 2-RC-133.Reactor coolant will now flow through the connected sightglass to the pressurizer relief tank.Monitor this tank level while draining this way and maintain the level less than 5%.6.9 When reactor coolant stops'flowing through the flow indicator connected to the head vent valve, close all drains.6.10 Place temporary refueling water.level indicator in service (tygon hose)by opening valves 2-RC-113-L3, 2-RC-116-L3, 1-WD-238, and temporary valve on tygon hose.Refer to Precaution 4.3.6.11 Continue draining the Reactor Coolant System by either or both methods of step 6.7 of this procedure.
Do not use the loo 3 drain for this because it will cause a false level indication.
6.12 As the indicated level approaches half loop, slow down the drainage and stop it when the level is reached.6.13 While maintaining level at half loop perform the following steps: 6.13.1 Close tne temporary valve on the leve'ygon at the PRT vent.6.13.2 Remove N supply from PRT by closing 1-GCR-30$.6.13.3 Slowly vent PRT to instrument room purge exhaust by cracking or throttling temporary valve.6.13.4 When PRT is fully vented, slowly throttle open temporary valve on the tygon level hose.6.14 Close RC-116-L3.
6.15 Close temporary valve on tygon level hose at PRT.Then disconnect the tygon.hose from the valve and have it run up alongside I3 RCP to a height greater than the reactor flange (greater than 622'levation).
