Dear Mr. Papanic:
SUBJECT:
RESPONSETOBULLETIN89-03(TACNO.75477)
On November 21, 1989, the NRC staff issued Bulletin 89-03 " Potential Loss of Required Shutdown Margin 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 shutdown margin of approximately 5%.
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 proceduros. This training should include the fundamental aspects of criticality control with enriched fuel assemblies.
By letter dated January 19, 1990, you responded to Bulletin 89-03 which indicated that programs at Yankee-Rowe Nuclear Power Station either are in place or will be implemented to address all three actions described above prior to your June 1990 refueling outage. Therefore, the staff considers your response to Bulletin 89-03 to be satisfactory and TAC 75477 to be closed.
