June 29, 1990 Docket Nos.
50-315 and 50-316 Hr. Hilton P. Alexich Indiana Hichigan Power Company c/o American Electric Power Service Corporation 1 Riverside Plaza
- Columbus, Ohio 43216
Dear Hr. Alexich:
SUBJECT:
D. C.
COOK UNITS 1 AND 2 - RESPONSE TO BULLETIN 89-03 (TAC NOS.
75417 AND 75418)
On November 21, 1989, the NRC staff issued Bulletin 89-03, "Potential Loss of Required Shutdown Hargin During Refueling Operations."
The bulletin requested that all PWR licensees and PWR construction permit holders take the actions described in the bulletin to ensure that an adequate shutdown margin is maintained during all refueling operations.
To accomplish this, three actions were described:
1.
Assure that any intermediate fuel assembly configuration (including control rods) intended to be used during refueling is identified and evaluated to maintain sufficient refueling boron concentration to result in a minimum margin of approximately 5X.
2.
Assure that fuel loading procedures only allow those intermediate fuel assembly configurations that do not violate the allowable shutdown margin and that these procedures are strictly adhered to.
3.
Assure that the staff responsible for refueling operations is trained in the procedures recommended in Item 2 above and understand the potential consequences of violating these procedures.
This training should include the fundamental aspects of criticality control with enriched fuel assemblies.
By letter dated January 26, 1990 (AEP:NRC:1111), your response to Bulletin 89-03 indicated that programs will be implemented to address all three action described above.
Therefore, the staff considers your response to Bulletin 89-03 to be satisfactory and TAC Nos.
75417 and 75418 to be closed.
Sincere ly,
/s/
