EDWIN I. HATCH NUCLEAR PLANT UNITS 1, 2 NUREG-0737 ITEM II.B.3 IWLEENTATION SCHEDULE Gentlemen:

In Georgia Power Company's letters of June 7, 1982. and December 20, 1982, schedules for implementation of NUREG-0737 Item II.B.3, Post-Accident '

Sampling Capability, were proposed for Hatch Unit 2 and Unit 1, respectively. It was estimated that implementation of Item II.B.3 would be completed by April.1,1983 for Unit 1 and by the end of the outage following Cycle 3 for Unit 2.

+ GPC hereby revises ' the estimated completion dates for Its II.B.3 to July 1,1983 for both Unit 1 and Unit 2. As discussed with Mr. George L

Rivenoark on March 4,1983, several recently identified factors contribute r to this delay.

[ The vendor of the on-line chloride analysis portion of the Post-Accident Sample Systs (PASS) has recently recommended that their equipment not be ,

installed as delivered. They have indicated that. the lifetime . of the chloride electrode' in a simulated post-accident environment is unacceptably  !
short, but- that several' promising approaches to increasing its lifetime are

- currently under investigation. Recognizing that on-line chloride analysis of post-accident reactor coolant samples is a state of the art technology, i

GPC feels that a three-month schedule allowance would be prudent. In the I event that on-line chloride analysis is not ~ available, grab sample analysis will be used. Furthermore, we are concerned that other electronic components may require replacement. This presents a potential delay of up to two months. The need will not be known until system testing has been j_ conducted.

j' Considering the aforementioned factors and the availability of interim

' measures for post-accident sampling, GPC considers the July 1, 1983 imp 1 mentation date for the Plant Hatch PASS to be justified.
