SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR' REGULATION SUPPORTING AMENDMENT NOS. 85 AND'68 TO FACILITY OPERATING LICENSES NOS.'DPR-53 AND DPR'69 BALTIMORE GAS AND ELECTRIC COMPANY

CALVERT CLIFFS NUCLEAR POWER PLANT U$1T NOS.'l & 2 DOCKET NOS. 50-317 AND 50-318 Introduction By application dated April 27, 1983, Baltimore Gas and Electric Company (BG&E) requested changes to the Technical Specifications (TS) for Calvert Cliffs Units 1 and 2.
The proposed changes to the'TS would (1) reflect changes in the on-site organization, (2) provide clarification for sur-veillance of certain sealed sources, and (3) delete the operability and surveillance reauirements for a safety-ralated snubber which has been removed from service (Unit 1 only).
Discussion and Evaluation i
BG&E has prooosed changes to Section 6.0 of the TS in two areas, namely figure 6.2.2 Organizaticn Chart - Calvert Cliffs nuclear Power Plant, and the composition of the Plant Operations and Safety Review Committee (POSRC) membership a; noted in Section 6.5.1.2.
These TS changes are reouired to reflect changes in the on-site organization at Calvert Cliffs.
The position cf Superviscr-Muclear Fuel Management is to be eliminated at Calvert Cliffs. The Nuclea-Fuel Management group will be divided into two parts, Incore Fuel Management and Fuel Cycle Management, both of~which report to the General Supervisor-Training and Technical Services.
A new position of General Supervisor-Planning and Support w.111 be formed with a Plar.ning and Support staff reporting to him, which will encompass the present responsibilities of the Supervisor-Administrative Services.
The job title of General Foreman and AssistantGeneraTForeman-Mechanical will be changed to General Supervisor-Maintenance.and Modifications and
~
Assistant General. Supervisor-Mechanical, respectively.
The job title of Supervisor-Calvert Cliffs Security will.belchanged to Assistant General Supervisor-Nuclear Security.
Proposed TS Figure 6.2.2 reflects these organizational and title changes.
Since the position of Supervisor-Nuclear Fuel Management will be eliminated, i
the Principal Engineer of Incore Fuel Management will replace the. Supervisor-Nuclear Fool Management as a POSRC member.
This proposed, change is re-l flected ia TS 6.5.1.2.

, We have reviewed the proposed changes to the Calvert Cliffs on-site organization as reflected in TS Figure 6.2.2.
We conclude.that the changes will not degrade the technical or administrative functioning of this organization and are therefore acceptable.
In addition, we find that the proposed change to TS 6.5.1.2 is acceptable in that the pro-posed change to the POSRC will not degrade the ability of the POSRC to advise the Plant Superintendent on all matter's related to nuclear safety at Calvert Cliffs.
BG&E has also proposed changes to TS 3/4.7.9, " Sealed Source Contamina-tion." The proposed changes would clarify the surveillance requirements for startup sources and fission detectors.
At the present time, TS 4.7.9.1.1 requires startup sources and fission detectors to be tested for leakage and/or contamination "...within 30 days prior to being sub-jected to core flux...". This TS could be interpreted to require sur-veillance prior to each reactor startup, thus resulting in the need to remove these sources from the reactor.
The proposed TS changes would transfer the words "...(excluding startup sources and fission detectors previously subject to core flux)..." from TS 4.7.9.1.2a to TS 4.7.9.1.2.
This change extends the stated exclusion from " sources in use" to all categories of sealed sources including startup sources and fission de-tectors.
In additicn, the words "...or installation in the core..."
would be inserteo in T3 4.7.9.1.2c to provide the clarification con-cernin'g the timing for performance of ieakage and/or cor.tamination ser-vaillance.
The Bases for TS 3.4.7.9 indicate the need for surveillance of sealed sources to "... ensure that leakage from byproduct, source.and special nuclear material sources'will not exceed allowable intake values." Once these sources undergo surveillance for leakage and/or contamination and are installed in the. reactor vessel, they are isolated by virtue of their location.
It was never the intent of the NRC to require thu these sources be removed for testing prior to each reactor ; tartan. This position is reflected in versions of the Combustion Engineering Standard Technical Specifications (CE-STS) issued by the NRC subsequent to the version of the CE-STS for Calvert Cliffs. Accordingly, we conclude that the proposed changes to TS 3/4.7.9 are consistent with the current NRC approach concerning surveillance for sealed sources.and are therefore-acceptable.
Finally, BG&E has proposed a change to the snubber operability and surveillance requirements of Calvert Cliffs' Unit 1.TS 3/4.7.8, " Snubbers",
This change would delete snubber 1-38-4 from the list of snubbers in TS Table 3.7-4.
This snubber was removed under an earlier modification.
wh'ich installed the Reactor Coolant System head vent and Pressurizer-vent piping. The system upstream of and including the main solenoid valve is Seismic Class 1 allowing removal'of the snubber, since the system is adequately supported and snubber 1-38-4 is no longer-required. Since the snubber is no longer needed or installed, no reduction in the' bases for any Technical Specifications would' result from this change,
F 3-l Environmental Consideration We hay 1 determined that the amendments do not authorize a change in effluert types or total amounts nor an increase in power ' level and i
will nct result in any significant environmental impact. Having made this determination, we have further concluded that the amendments involve an action which-is insignificant from,the standpoint of environmental impact and, pursuant to 10 CFR 51.5(d)(4),thatan i
environmental impact statement or negative declaration and environ-mental impact appraisal need not be prepared in connection with the i ssuance of the amendments.
I Conclusion We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the l
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 ano security or to the health and safety of the public.
