l ENCLOSURE i
l VITAL EQUIPMENT / AREA GUIDELIFES STUDY ACTION PLAN Obiectives of Study Develen e conrrebensive and consistent set of recommended assumptions, per nrrence r
criteria and cuidance, in a report to the EDO, for deternining vital equipment /
areas in nuclear power plants.
The assumptions and guiderce should:
1.
Consider conditions of normal operation, includitg anticipated aparational occurrences, and those transients and acciderts of the types presently
'l considered in the design basis analysis of nuclear power plants; 2
Consider nutage activities to the extent that loss of crerational functions and capebilities during outages impacts vital equiprent; 3
Be readily apolicable to identification of required vi+el coutpment and areas on a case-by-case basis; and t
4.
Have review and reneurrence of all cogni7 ant offices.
Scope of Study i
The Vital Area Comittee (VAC) will:
1.
Review all regulations, guidarce, definitions, assumptions and criteria currently in effect related to deterrination of vital equipment and i
areas; 2.
Determine the present status of the application of the items in (1) l above to various vintages of plants to estehlish what staff practice has been and is at present wi+h respect to approvinn designated vital equip-ment and areas; 3.
Tr'ertify eny deficiencies, anbiguities, inconsistencies and other prnb1ers in the present regulatory approacht 4
Review and evaluate recent and current staff proposals, proposed rules, etc., es they relate to and impact vitel equipment and areas.
For example, this would include the 'clieving:
Prctection of event mitigating capabilities and their support e.
facilities; e.a., water sources, pumps, switchgear, cable runst b.
Constraints on vital island concent and compartmentalization raquirerents; I
r
r e
l
-p.
l Acceptable final state (hot vs. cold shutdown), required duration I
c.
of that state, reliance on outside assistance, and consideration of normal equipment repair capabilities; d.
Provisions for correnseting for vital equipment which is out of service for maintenance; e.
Credit for plant-specific features and capabilities such as feed-t and-bleed; f.
Information, data and recommendations from recent staff end contractor studies as well as operational experience relevant to vital coutpment and areas; and i
p.
Methods used to protect critical equiprent for other purposas, such as fire protection.
Study Methodology i
The 'ollowing approach is planned for Vital Area Corrittee information and data acquisition and assessment:
1.
Independent VAC review and evaluation of all relevant documentation; and 1
2.
A series of briefings to the VAC by staff and NRC contractors, as 2
outlined in Atterbrent 1 (note that these briefings have been completed).
I Schedule The attached figure (Attachment 2) shows the milestones and tartet dates for the first phase of the study which will produce preliminary recommendations totheManapenentPolicyReviewGroup(MPRG). The belance of the study will involve obtaining necessary coerurrences of the recommendations and preperf rg a report.
