POINT BEACH NUCLEAR PLANT 01150 OPERATING INSTRUCTIONS SAFETY RELATED Revision 1 HEATING THE CONDENSATE STORAGE TANKS April 12, 2001 INITIALS NOTE:
Due to Improved Technical Specifications (ITS) implementation, in order to allow use of this procedure prior to and after implementation, both the custom and improved Technical Specification information is shown, with the ITS information in Braces. Example: CTS info {ITS info}
1.0 PURPOSE This procedure provides instruction for filling the Condensate Storage Tank, T-24A or T-24B from the opposite units Condensate Feedwater System or Waste Condensate System to provide approximately 42,000 gallons of water at a temperature of 950F (80 OF to 110 OF) to fill the Steam Generator and Main Steam line.
2.0 PREREQUISITES The IT-300/305 transfer hose (rated at greater than 2000 psig) is available for use.
3.0 PRECAUTIONS AND LIMITATIONS 3.1 Do NOT allow CST temperature to exceed 120 Degrees F during the fill 0 ".with a final target temperature of approximately 110 degrees F.
3.2 Observe appropriate safety precautions when IT-300/305 transfer hose is pressurized. The temperature and pressure could be approximately 210'F and approximately 400 psig.
4.0 INITIAL CONDITIONS 4.1 Ensure greater than 13,000 gallons usable condensate volume in each CST if required by current plant conditions per CTS 15.3.4 {ITS 3.7.6).
4.2 Permission to Perform Evolution The conditions required by this evolution are consistent with required plant cond ions including equipment operability. Permission is granted to perform t s evolution.

POINT BEACH NUCLEAR PLANT OPERATING INSTRUCTIONS HEATING THE CONDENSATE STORAGE TANKS 01150 SAFETY RELATED Revision 1 April 12, 2001 INITIALS 5.0 PROCEDURE NOTE:
If both Units are in Cold Shutdown {ITS MODE 5, 6, or defueled}then heat the CSTs using Waste Heating Returns per section 5.3 or 5.4 as applicable.
NOTE:
Approximately 42,000 gallons of water will be needed to fill the Steam Generator and Main Steam line. This will require multiple filling of the target CST.
NOTE:
Maintain a minimum of 13,000 gallons of water in the target CST to satisfy the on-line units technical specification for Auxiliary Feedwater source volume.
NOTE:
It will be necessary to perform this procedure more than once to fill the SG and MS line and maintain the minimum CST TS required level.
NOTE:
Each section of the procedure stands alone. Perform only the section(s) required.
5.1 Heat T-24A (South) CST to between 80 and 110 degrees F. using Unit 2 2A Feedwater Heater.

POINT BEACH NUCLEAR PLANT OPERATING INSTRUCTIONS HEATING THE CONDENSATE STORAGE TANKS 01150 SAFETY RELATED Revision I April 12, 2001 Install IT-300/305 transfer hose by:
- a. Connect one end of IT-300/305 transfer hose to 2CS-107C, HX-17A LP FWH 2A Outlet to HX-19A LP FWH 3A DRN.
- b. Connect the other end of IT-300/305 transfer hose to AF-13, T-24A CST Drain.
CAUTION Feedwater outlet temperature is approximately 210 OF and approximately 400 psig. When the transfer hose between Unit 2 2A FW Heater and T-24A is used, AF-13 is to be opened before throttling open 2CS-107C and 2CS-107C is to be shut before shutting AF-13 to minimize the pressure on the transfer hose.
Hang Temporary Information tags containing the information in the Caution above on:
- a. AF-13, T-24A CST Drain.
Open AF-13, T-24A CST Drain.
NOTE:
2CS-107C, HX-17A LP FWH 2A Outlet to HX-19A LP FWH 3A DRN, may be throttled open or closed to vary fill or rate of temperature change.
NOTE:
Steps 5.1.5 and 5.1.6 or 5.1.7 may be performed concurrently.
Using the tool provided, throttle open 2CS-107C, HX-17A LP FWH 2A Outlet to HX-19A LP FWH 3A DRN AND check hose for leaks.
