Dear Mr. Bradham:
SUBJECT:
RESPONSETOBULLETIN8903(TACNO.74564)
On November 21, 1989, the NRC staff issued Bulletin 89 03, " Potential loss of Required Shutdown Margin During Refueling Operations." The Bulletin requested 1
that all PWR licensees and PWR construction permit holders take the actions described in the Bulletin to ensure that an adequate shutdown margin h i
maintained during all refueling operations. To accomplish this, three actions i
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%.
1 2.
Assure that fuel loading procedures only allow those intermediate i
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 reconvended in item 2 above and understand the potential consequences of violating these pro:edures.
Thh training should include the fundamental aspects of criticality control with enriched fuel ass <;mblies..
By letter dated January 5, H90, you reipended to Bulletin 89 03 wHch ir.d',cated that Action 1 and 2 have been addressed and that Action 3 will be impitverted by the Harch 1990 refue~dng cutage. Tiierefore, the staff considers your response to Bulhtin 89-03 to be sathfactory and TAC No. 74564 to be closed.
Sincerely.
