SUBJECT:
LICENSING ACTION REVIEW FOR PILGRIM - PROPOSED REVISIONS TO TECHNICAL SPECIFICATIONS OF SURVEILLANCE INSTRUMENTATION (TAC #57510)
I Region I has reviewed the Boston Edison Company's request dated April 12,.1985, to change the calibration frequency for the reactor level, reactor pressure and i
drywell pressure surveillance instrument channels in Technical Specification l
Table 4.2.F from once per six months to each refueling outage.
The licensee provided information to extend ihe frequency to once each 18 months.
Technical Specifications define refueling outage, for the purpose of surveillance inter-vals is a regularly scheduled outage unless the regularly scheduled outage i
occurs within eight months of completion of a plant refueling outage. This definition as well as the schedules indicated in the Long Term Program issued as Amendment 75 to the facility license, which defines the regularly scheduled outages, can exceed 18 months. The SE was written as agreed by the Project Manager, Paul Leech, based upon an 18 month calibration frequency in lieu of i
the licensee's proposal for a refueling outage frequency.
Therefore, the l
licensee will need to modify their request for change in the calibration fre-quency from once each refueling outage to once each 18 months.
Enclosed is a modified technical specification page which describes the type of changes needed to satisfy the SE.
The Project Manager also agreed to obtain the licensee submittals to reflect the SE.
As stated in the enclosed safety evaluation, an 18 month calibration frequency change was found to be accept-able.
The SALP input for TAC 57510 is enclosed.
This review also identified an apparent conflict in Table 4.2.F and the Standard Technical Specifications (STS).
Specifically, the STS require an 18 month calibration frequency for the safety / relief valve position indicators, tcrus water level, and primary containment pressure; whereas, the Pilgrim 1
Technical Specifications specify each refueling outage.
For the sama reasons c
as stated above, each refueling outage can exceed 18 months.
These sensors i
provide similar surveillance information to those requested in TAC 57510. This l
fact is provided for your information.

ENCLOSURE 1 SAFETY EVALVATION SUPPORTING AMENOMENT NO.
TO FACILITY OPERATING LICENSE NO. OPR-35 BOSTON EDISON COMPANY e
PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 Introduction and Background By letter dated April 12, 1985, (Reference 1), and letter dated (Reference 2) Boston Edison Company (the licensee) proposed to amend its opera-ting license, OPR-35 by modifying the Ptigrim Nuclear Power Station Technical Specifications.
The proposal would change the calibration frequency for the reactor level, reactor pressure and drywell pressure surveillance instrument channels in Technical Specification Table 4.2.F from once every six months to once each 18 months.
The licensee, during a recent refueling cutage, replaced the existing GEMAC transmitters with Rosemount transmitters, Model Numbers 11520P and 1152GP.
This replacement was made because the GEMAC transmitters are obsolete and replacement parts are unavailable.
A Notice of Consideration of Issuance of Amendment to License and Proposed No Significant Hazards Consideration Determination and Opportunity for Hearing related to the requested action was published in the Federal Register on May 21,1985 (50 FR 20970) for hearing and no pubite comments were received.
Evaluation l
The reactor level, reactor pressure and drywell pressure surveillance instru-ment channels provide indication of plant status. The subject instruments do not provide any automatic actuation of safety systems, and therefore, the change does not affect any engineered safeguards actuation system (ESAS).
The surveillance requirements (SR) for the reactor level, reactor pressure, and drywell pressure surveillance instrument channels also include an instrument l
check each shift, as specified by Technical Specification (TS) Table 4.2.F.
The instrument checks for the above surveillance instrument channels will remain unchanged by this amendment.
l i
2 The licensee's request for a decrease in the calibration frequency from 6 months to 18 months for the Rosemount transmitters is supported by the General Electric Licensing. Topical Report NEDO-21617-A, Class I dated December, 1978, "Analog Transmitter / Trip Unit System For Engineering Safeguard Sensor Trip Inputs".
By letter dated June 27, 1978, the Commission reviewed and found the report acceptable for reference in license applications.
The NEDO-21617-A recommended frequency of calibration for these type transmit-ters is 12 to 18 months.
Based upon the al.ve, the staff finds that the proposed change to the subject technical specification calibration frequencies will not involve any pnysical change to the plant safety related systems, components or structures, will not increase the likelihooo of a malfunction of sTfety related equipment, will not increase the consequences of an accident prtviously analyzed, nor create the possibility of a malfunction different from those previously evaluated.
The staff therefore finds the licensee's requestec change of calibration frequen-cies for the reactor level, reactor pressure aad drywell pressure instrument channels from once every 6 months to once each 18 months to be acceptable.
Environmental Consideration This amendment involves changes in the installation or use of a facility com-ponent located within the restricted area as defined in 10 CFR Part 20 and changes in surveillance requirements.
The amendment also relates to a change in recordkeeping, reporting and administrative requirements.
We have deter-mined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released of f-site, and that there is no significant increase in individual or cumulative occupational radiation exposure.
The Commission has previously issued a pro-posed finding that this amendment involves no significant hazards consideration and there has been no public comment on such findings.
Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and (10).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
Conclusion We have concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.

f Reviewer:
D. Florek and E. Vanterpool The Itcensee was very responsive to requests for clarification of their pro-posal.
Based on their request and clarifying information, it allowed prompt and efficient evaluation of the proposed change.
Had the clarifying infor-l mation been included with the original proposal, no additional information t
would have been required to evaluate the change.
