Additional Information for Application for Amendment to Operating License Reactor Coolant, Activity Technical Specifications R.E.

RG&E Letter, R.

Mecredy to A.

Johnson (NRC),

"Application for Amendment to Operating License Reactor Coolant ActivityTechnical Specification,"

May 23, 1994.

Dear Mr. Johnson:

As a result of an October 25, 1995 telephone conversation between RG&E and members of the NRC staff the following additional information is supplied to supplement Ref. (a):

Attached is tabular date for Ref.

(a) Figure III.lwhich is break flow flashing fraction for Cases 1 and 2.

2 ~

Attached is tabular data for Ref.

(a) Figure III.2 which is scrubbing efficiency for Cases 1 and 2.

3.

4 ~

5.

The dose calculations done in Ref.

(a) used a total primary coolant activity value of 100/E p, Ci/gm.

The initial steam generator mass prior to break initiation used in the Ref.

(a) calculations was 3.39 x 107 gm per steam generator as listed on page 48 of Ref. (a).

An evaluation of the control room doses associated'ith a

steam generator tube rupture indicates that the doses are significantly less than the doses associated with a large break loss of coolant accident.

Therefore, control room doses remain bounded by the LBLOCA doses.
