The reactor trip system' components are treated as Safety-Related

-General Paragraph A.
New ETI will be forwared to the ETI l
. Coordinator for review;-existing ETI will be reviewed in accordance with section 2.0 of ZAP 6-52-5.
The evaluation and implementation of the NUTAC program has been
-described by means of the Nuclear Stations Division (NSD) Directive MO-2, Contro1Lof Vendor Equipment Technical Information, revision 2, March 4, 1985.
This directive is the source document from which the Zion Nuclear Station Administrative Procedure (ZAP) for Control of Vendor Equipment Technical Information was written.
.Both the Nuclear-Stations: Division Directive and the Zion Station
-Administrative Procedure adequately address those conditions under which vendor interface must be exercised and therefore established and maintained.
4-
. The NSD Directive MO-2 meets.all of the requirements of the NUTAC program regarding vendor interface and supplements, clarifies and enhances that interface where necessary.
The ZAP was written in accordance'with NSD Directive MO-2 and therefore addresses those conditions'under which vendor interface should be exercised.
With regard.to vendors who-provide maintenance.or. testing services on safety-related equipment, the CECO Quality Assurance Manual
- assures that needed control over procedures and maintenance instructions is maintained by'all vendors.
The NSD' Directive-M0-2 and ZAP 6-52-5 are enclosed for your review.
