Subject:
NRC Request for Additional Information Regarding the Response to Generic Letter 97-01, Degradation of Control Rod Drive Mechanism Nozzle and Other Vessel Closure Head Penetrations
' E adies and Gentlemen, On April 1,1997, the Nuclear Regulatory Commission (NRC) issued Generic Letter (GL) 97-01 (Toledo Edison Log Number 5027), requesting that licensees for the Davis-Besse Nuclear Power Station (DBNPS), Unit Number 1, provide a description of their program for ensuring the timely inspection of the reactor's control rod drive mechanism (CRDM) nozzles and other vessel closure head penetrations (VHP). The generic letter requested
- specific information regarding CRDM nozzle and other VHP inspection activities, and also a description ' f any ion exchange resin bead intrusions and their effect on the o
primary water chemistry, Toledo Edison (TE) initially responded to the generic letter by letter (Serial Number 2439a) dated April 23,1997 and committed to providing a final
- response to the NRC by July 29,1997.
The final response to GL 97-01 (Serial Number 2472), dated July 28,1997 provided TE's endorsement that the integrated response developed by the Babcock & Wilcox Owners Group (B&WOG) applies to the DBNPS. The B&WOG response is documented in B&WOG Topical Report, B AW-2301 titled "B&WOG Integrated Response to Generic Letter 97-01: Degradation of Control Rod Drive Mechanism Nozzle and Other Vessel 3f Closure Head Penetrations." Topical Report BAW-2301, dated July 1997, has been fi submitted to the NRC.

- Docket Number 50-346 License Number NPF-3 Serial Number 2569 Page 2 to the DBNPS. Similar NRC requests for additional information have been or will be issued to other PWR licensees.
On September 29,1998, the Alloy 600 Issue Task Group of the EPRI Materials
. Reliability Project met with the NRC staff to discuss proposed actions to respond to the NRC RAls on licensee responses to Generic Letter 97-01. The task group has developed a plan for a generic response that may be used by PWR licensees. Draft responses to the RAI questions are being developed by the Owners Groups, EPRI, NSSS vendors, and contractors, as appropriate. These responses will be integrated into a single response by NEI and submitted to the NRC.
The NRC staff indicated general agreement with industry's approach and agreed that licensees could extend their plant response submittal dates to January 15,1999.
l Accordingly, the DBNPS is requesting this extension in order to participate in the l
industry's approach and to incorporate the generic response into a DBNPS-specific response.
Should you have any questions or require additional information, please contact Mr.
James L. Freels, Manager - Regulatory Affairs, at (419) 321-8466.
