Dear Mr. Denton:
Serial No. 311 PO /HSM: sm.v Docket Nos. 50-280 50-281 License Nos. DPR-32 DPR-37 During the Surry Unit No. 2 Steam Generator Replacement Outage, the reactor coolant pipe was decontaminated after being cut out and was reused after the new steam generators were installed.
In evaluating the Unit 2 steam generator replacement outage for possible changes for the Unit 1 outage, it was found that there are schedular and personnel exposure savings which could be accrued by purchasing new reactor coolant pipe instead of reusing the old pipe.
Dur-ing the Unit 2 outage, approximately 41 manrem was expended in the decontami-nation of the reactor coolant pipe,which could be saved by buying new pipe.
As a result of the above evaluation, another evaluation was performed to determine the best means for disposal of the reactor coolant pipe.
Three options were considered:
Option 1:
Option 2:
Option 3:
Onsite Storage In Steam Generator Storage Building Intact Shipment Offsite For Burial Onsite Sectioning and Offsite Shipment For Burial All three of these options are feasible, however, Option 1 is more preferable from an occupational exposure and economic standpoint.
The reasoning behind this selection is essentially the same as the rationale used in selecting this option for the retired steam generator lower assemblies.
This rationale is discussed in our submittal describing the Steam Generator Replacement dated August 17, 1977.
For the above reasons, onsite storage is the option we are pursuing for dis-posal of the reactor coolant pipe.
Preparation for storage in the steam generator storage building will consist of welding a cap on each end of the reactor coolant pipe pieces and painting the pipe* to fix to the surface any loose surface contamination.
The shielding that will be attached to the pipe prior to removal from the reactor coolant system will be left on the pipe while in storage.
