{{#Wiki_filter:}}
 
==Dear Sir:==
 
Pursuant to Section 50.90 of the Commission's Rules and Regulations, Boston Edison Company hereby proposes the following modifications to Appendix A of Operating License No. DPR-35.
Proposed Change Sections 3.7.D.1 and 3.7.D.2 " Primary Containment Isolation Valves" currently state:
3.7.D.1  During reactor power operating conditions, all isolation valves listed in Table 3.7.1 and all instrument line flow check valves shall be operable except as specified in 3.7.D.2.
t I                              3.7.D.2  In the event any isolation valve specified in Table 3.7.1 becomes inoperable, reactor              i O OI m e:                              power operation may continue provided at
  -@ g                                  least one valve in each line having an in-
,      9                                  operable valve is in the mode corresponding g                                  to the isolated condition.
The desired change consists of clarifying the existing wording to reflect the g"f o                intent of these Limiting Conditions of Operation. As such, these Sections are required to be revised as follows:
l    %
l Whenever primary containment integrity is
  ,.8g<                          3.7.D.1 l jd                                      required, all isolation valves listed in l

* Table 3.7.1 and all instrument line flow l                                        check valves shall be operable except as l                                        specified in 3.7.D.2.

CDLTON Eos QN COMPANY Mr. Domenic B. Vassallo, Chief September 30, 1982 Page 2 3.7.D.2  In the event any isolation valve specified in Table 3.7.1 becomes inoperable, at least one containment isolation valve in each line having an inoperable valve shall be placed in the mode corresponding to the isolated condition.
Reason For Change The intent of these Technical Specifications is to allow operation in and between all reactor modes when an isolation valve is inoperable, and satisfy the conditions for primary containment integrity when required.
Safety Considerations A safety evaluation has been performed and has determined that the desired change does not represent an unreviewed safety question as defined in 10 CFR, Part50.59(c). The bases utilized to reach this conclusion are: 1) the af-fected lines are in their isolated condition (which is the LC0 requirement);
: 2) system functions which may be affected by operation with valves in their isolated condition are addressed by the individual LC0's.
This change has been reviewed and approved by the Operations Review Comittee and reviewed by the Nuclear Safety Review and Audit Comittee.
Schedule of Change This change will be put into effect upon receipt of NRC approval.
Fee Consideration Boston Edison proposes this as a Class II type change, since it serves only to clarify an existing technical specification. Accordingly, a check for $1,200 will be forwarded to your office.
