g T~ne purpose of the' 4. wied transient and accident analyses is to provide an increase in safety by fsproving the performance oh reactor i operators during transient and accident conditions. The analyses that

[

support guideline and procedure development are to censider, therefore, the occurrences of multiple and conseques;tial failures. The provisions of this Itcs are described in. detail in IUREG-0737, titled "Clarifica-f tion of lWI Action 71an Requirements' (November 1980), at p. I.C.1-1. .

The iiGG submitted a detailed description of the program lto neet the provisions of Item I.C.1 by letter CG-61 dated July 7,1981 (fres Jurgenson to Hanauer) (copy attached). The NRC accepted'that proposed 1 progran for respcading to Ites I.C.1 by letter of September 18, 1981 (frc= Eisenhut to Jurgenson) (copy attacted).

k In accordance with this program, the WOG supplied to the MRC emer-1 5

gency response guidelines based upon analyses of various LOCA and non-h LOCA transients. See letter OG-M from Robert W. Jurgenson (Chair: nan, e

i WGG) to D. G. Eisenhut (Director, Division of Licensing, Office of MRR, w

H y Nuclear Regulatory Cannission), dated November 30, 1981. Mditional e

The emergency response guidelines include background sections which pro-

e vide additional trarsient analysas as a basis for the guiMfmes. The criteria for establishing a. basis for selecting mitiple failures in the guidelines is presented in WCAP-9691 and WCG 1eiiter OG-54 dated March 18, 1981 (from Jurgenson to Hanauer) (copy attached). Based on the guide--

lines and procedures proposed in response to this Iten, the ability'of operators to respond properly to transients will be improved.. 'Further, current operator training programs will be enhanced by additional in-sight iato the course of events likely to be encountered during a

! transient.

ACTION PLAM ITEM II.K.3.30 This Action Plan Its provides that NSSS vendors revise, document .

and submit to MRC for approval their small-break LOCA analyses upon taking into account and comparing results with experiser.tal data, in-cluding data fra the LOFT and Seniscale tests. The purpose of this b

Westinghouse Electric Corporation to Eisenhut) (copy attached). Westinghouse has coanitted to submit a draft report on its nvised model to the NRC by April 1,1982 in letter MS-EPR-2524" dated November 25,1981 (from E. P. Rahe, Planager Nuclear 5afety Department.

As part of this effort, Westinghouse has performed blind test pre-
