Dear Mr. Schnell:
f
SUBJECT:
RESPONSE TO NRC BULLETIN 89-03 (TAC NO. 75410)
On November 21, 1989, the NRC staff issued Bulletin 89-03, ' Potential Loss of Required shutdown Margin During Refueling Operation." 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 51, 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 a)ove and understand the potential consequences of violating these procedures. This training shoulti include the fundamental aspects of criticality control with enriched fuel assemblies.
