Dear Mr. Shelton:
SUBJECT:
RESPONSE TO BULLETIN 89-03 (TAC NO. M75420).
On November 21, 1989, the NRC staff issued Bulletin 89-03 " Potential loss of Required Shutdown Margin During Ref u ling 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 pa tedures 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 February 13, 1990, you responded to Bulletin 89-03 which indicated that programs are in place or would be implemented prior to fuel movement to address all three actions described above. Therefore, the staff considers your response to Bulletin 89-03 to be satisfactory and TAC No. M75420 to be closed.
Sincerely,
/S/
