Gentlemen:
RESPONSE TO GENERIC LETTER 89-16 INSTALIATION OF HARDENED WETWELL VENT FACILITY OPERATING LICENSE'NPF-57 HOPE CREEK GENERATING STATION DOCKET NO. 50-354 On September 1, 1989, the NRC issued Generic Letter 89-16 to r
inform the owners of BWR plants with Mark I containments of the NRC program for disposition of issues related to the Mark I Containment Performance Improvement Program.
This letter encouraged utilities to. voluntarily install a hardened vent under the provisions of 10 CFR 50.59.
Our review of SECY 89-017 indicates that the primary benefit of the' hardened vent:is the reduction of risk associated with the TW (loss of decay heat removal) sequence.
The Hope Creek Generating Station (HCGS) has an existing six inch hardened vent, the use of which is currently controlled by Emergency Operating Procedures.
This vent is of sufficient size to reduce containment pressure and suppression pool temperature to provide adequate venting capability for the.TW sequence.
Public Service Electric and Gas Company (PSE&G) will be working with the BWR Owners' Group to develop generic design criteria that address the hardened vent issue.
It is anticipated that th9 design criteria will be available for NRC review by April 30, 1990.
HCGS-specific design details will be reviewed against the generic criteria established and any upgrades to the existing six inch vent design will be developed as PSE&G completes the appropriate portions of the Individual Plant Examination (IPE) for HCGS and studies the possibility of system interaction effects between the proposed upgrades to the vent and existing plant design.

1 Document Control Desk 10-30-89 NLR-N89220 Based upon NRC acceptance of the generic criteria within 6 months of submittal by the BWR Owners' Group, any upgrades to our existing six inch hardened vent will be completed prior to restart following the second refueling outage from the date of this letter or January 1, 1993, which ever is later.
It 4 3 the belief cf PSE&G that the risk of the TW sequence is already low.
Upgrading the existing hardened vent will further reduce the risk of this sequence and make a significant contribution to closing the NRC's Mark I Containment Performance Improvement Program.
