Docket No. 50-247 i
t
Dear-Mr.-Denton:
Consolidated Edison Ccm1pany of New York, Inc. (Con Edison) transnits herewith three (3) sigrai originals and ferty (40) copies of a dmnant entitled " Application for headre.nr. to Operating License," sworn to en November 3, 1978. This Application requests an amendment to the Technical specifications for Indian Point Chit No. 2. The proposed Technical
[
Specification changes, contained in Attachment A to this Application, j
would establish limiting conditions for operation (ICOs) and surveillance i
requirenents for the recently i:tstalled Indian Point Unit No. 2 Overpressure Protection' System (CPS) in response to Mr. A. Schwencer's August 28, i
1978 letter to Mr. William J. Cahill, Jr. A Safety Evaluation of the proposed changes is presented in Attachnent B to this Application.
4 I
Based on plant design and cperational experience to date, Con Edison Miwes that the use of a pressurizer bubble durig startup of
_the-Anitial reactor coolant pmp (PCP) significantly reduces the effects
-[
of reactor coolant sycan (BCS) pressure transients and the potantial 4
i for exceeding the 10 CFR 50, Appendix G, limits. The pressurizer bubble i
s Li:cdon beycnd that provided by the CPS alone. In addition, i
affctds c
since we instituted the use of the pressurizer bubble at Indian Point 2, we have not experienced an overpressure ire.:ident. However, to establish j
a minimun hele size fer use as a technical specification limit, further detailed analyses need to be pw.fcurel. Since Ccn Edisen believes that
[
the current use of a pressurizer bubble represents an important and i
viable option, we are unde.% the analytical effort required to I
establish a minimum bible size.
t I
i We are filing this Acplication at this ti:ne to accmmodate the Fegulatcry Staff's review cf cur everall CPS technical specificaticn l
package. It is pre.mr.tly anticipated that an amerdnent to this Applicatien l
will he filed in Decenber,1978 to incorporate the results of the pressurizer-i bubble evaluation.
