Dear Mr. Butler:
An inspection of the Peach Bottom Hydrogen Water Chemistry (HWC)
Installation was performed by the NRC on August 11, 1987. This letter provides information in response to requests made during the inspection.
I The inspection covered the HWC system, which is still under construction, including the hydrogen and oxygen storage system sites, the injection system control station, the system control panels, and the chemistry and materials j
monitoring instrumentation. During discussions, the NRC representatives requested detailed infomation on the system design.
This information is enclosed (Enclosure 1), c.onsisting of P&lD M-336, Sheets 1 and 2; Hydrogen Detection Shrouds, Sketch No. SK-39775-P1, Sheets 1-9; and the PBAPS HWC Mini-Test Final Report.
Prior to the system inspection, a discussion was held concerning the status of the NRC review of the Peach Bottom Technical Specification amendment request for a Maln Steam Line Radiation Monitor (MSLRM) setpoint change (reference 1).
The NRC requested additional information concerning the station's ability to detect and respond to fuel failures which were less than the revised trip setpoint. The question, and our complete response, is included as Enclosure 2.

_ Discussion at the site also Indicated that the NRC 1s expecting j
to issue an SER for Peach Bottom which would address the complete system installation.
Philadelphia Electric's submittals for HWC to date have addressed only the MSLRM C a nt Change (reference 1) which is a Technical Specification chec3e, and the storage of hydrogen and oxygen Creference 2).
As requested during the inspection, we are transmitting herewith for your information our 10CFR50.59 evaluation for the hydrogen / oxygen injection systems along with a review of our system's design confonnance to the EPRI "Guldelines for Permanent HWC Installations" (Enclosure 3).
The NRC has recently accepted the Guidelines (reference 3) for use in HWC IIcensing. As detailed in our Enclosure 3, our design is in confonnance with the Guidelines.
Should you have any questions or require additional information, please do not hesitate to contact us.
Very truly yours, CMC /cmv/08128706Y Enclosures Copy to:
