Subject:

Zion Nuclear Power Station, Units 1 and 2 License Nos. DPR-39 and DPR-48 i

NRC Docket Nos. 50-295 and 50-304 Proposed Amendment to Technical Specification Sections 3.1 and 4.1. "Rgartor Protection System" i

Gentlemen:

Attached is a proposed Technical Specification amendment for Zion Nuclear Power Station, License Nos. DPR-39 and DPR-48.

The proposed amendment addresses Sections 3.1 and 4.1 " Reactor Protection System".

The purpose of this revision is to demonstrate compliance with NRC Generic Letter 85-09, entitled " Technical Specifications for Generic Letter 83-28, Item 4.3".

The proposed Technical Specification change involves additions and clarifications to Tables 3.1-1 and 4.1-1 to address operability and surveillance requirements for Reactor Protection Channels.

Specifically, this

. proposed amendment will change and/or clarify the operability and surveillance requirements for the following functions:

1) Manual Reactor Trip; 2)

Automatic Reactor Trip Logic; and 3) Reactor Trip and Bypass Breakers.

A summary of the changes is provided below.

1)

Iahle13-L_page_30 Line_3 The line is changed to correct a spelling error.

l 2)

Jable 3.1-1. pAgas_3L3nd_32 dine _2. Land _ explanation of ED _fontaole The description of the Reactor Protection Channel has been changed from " Automatic Reactor Trip Logic" to " Automatic Reactor Trip Logic, Including Reactor Trip Breakers".

The change reflects the request of NRR technical reviewers regarding reactor trip logic, and is closely patterned after similar requirements in effect at Ginna.

The (#)

footnote has been added to clarify the appropriate action if one of l

the diverse trip features is inoperable.

This footnote is worded in

(

accordance with Generic Letter 85-09.

3) lable_4J-1mpage_35mLtne 1 A note has been added to the " Remarks" column of Line 1 to address OPERABILITY of the undervoltage and shunt trip circuits, of the reactor trip breakers in addition to the OPERABILITY requirement of l

the reactor bypass breaker circuit.

These remarks closely parallel the guidance contained in Generic Letter 85-09.
