~hardenedwetwell'ventattheQuadCitiesNuclearPowerStation(QCNPS), Units a

1 and'2.

Inl reference (a), CECO comitted to provide hardened vents at QCNPS

by January 1,:-1993 in accordance with Boiling Water Reactors Owners Group (BWROG) design criteria to~be approved'by the NRC.

-The NRC staff reviewed reference (a), and determined that Ceco's-intentions to

^

--install a hardened wetwel1~ vent'at QCNPS under the-prov_isions of 10 CFR:50.59

.is acceptable. Since the staff views CECO's stated intentions to be a firm comitment to install the requisite modification, the NRC will not' proceed with backfit analyses for QCNPS.

If the staff's: understanding is not con-

+-

sistent with Ceco's intentions, you are requested to provide a detailed explanation to support deviations from the staff's understanding of:comit-mentsmadeninreference(a).

'The use'of results from Individual Plant Examinations (IPE) to develop f

' supplemental' criteria for the vent modification design is acceptable provided that it does not, in any way, affect the comple+. ion schedule or Ceco's o

comitment to make the requisite modifications under the provisions of j

10 CFR 50.59.
