W. G. Counsil letter to H. R. Denton dated December 31, 1979.
Gentlemen:
Millstone Nuclear Power Station, Unit Nos. 1 and 2 Technical Support Center and Emergency Operations Center In Reference (1), Northeast Nuclear Energy Company (NNECO) provided responses to all the Short-Term Lessons-Learned requirements, including a brief description of the various cuergency response centers which have been/will be established in fulfillment of the NUREG-0578 requirements. During the NRC site visit of January 14 and 15, 1980, Staf f representatives expressed some reservations regarding NNECO's proposals to fulfill the requirements of the Technical Support Center (TSC) especially as they relate to NNECO's Emergency Operations Center (EOC).
During telephone discussions on February 1, 1980, the Staff requested additional information regarding the proposed long-term EOC.
Accordingly, the following information is provided.
The centers will be upgraded as noted in Reference (1) to fulfill long-term implementation requirements.
Further details of the long-term EOC are provided below.
Loca t ion The EOC would be located approximately 1-1/2 miles from the Millstone Unit No.1 and dillstone Unit No. 2 reactors as shown on the enclosed map.
From this location, access to and egress from the plant could be readily controlled from the EOC.
This would minimize confusion within the site security boundary and yield better accountability of personnel.
Boon ge&2 -
habitability The EOC would have both direct shielding protection (reinforced concrete walls and ceiling) and airborne contaminant protection (filtered ventilation) compatible with the criteria used for the control rooms. These features, in conjunc-tion with the physical distance from the postulated radiation source, would render the center operational at all times.
Procedures to move any part of this operation to the TSC or other more remote locations are, therefore, not required.
Size The center as detailed on the attached drawings, is approximately 10,800 square feet and has been designed to accommodate approximately 70 people.
Security Requirements The two entrances / exits would be configured to ensure that only designated pecple are allowed access to the EOC.
Emergency Power Supply An emergency power supply system would be established to power all vital components. Options for this system are presently being evaluated.
Access Access to the EOC would be via the main plant access road (from the plant) or Rope Ferry Road (from offsite). This is the most easily accessible location which is available.
Communications and Data Links The dedicated phone lines and control rooms' video systems presently established within the the short-term EOC which is in the Millstone Unit No. 3 warehouse /
Millstone Unit No. 2 Condensate Polishing Facility, would be moved to this long-term location.
Other Building Purposes Although it is conceivable to utilize this center for training and other purposes, no plans are being considered at this time.
In the event that the center is utilized for another purpose at a later date, no major modifications of the emergency center section of the building are anticipated.
Functions Performed in tue TSC and EOC/ Level of Management in Each The proposed organization for site emergency responses consists of one director and seven managers as detailed below.
Director of Site Emergency Operations Location:
Site Function: Overall responsibility for site emergency operations, response, and activities with the objective of taking the unit to a safe shutdown condition in a manner which minimizes the ef f ec t on the health and safety of the station personnel and the public.
The Director will coordinate station emergency organization acr4 71..;
rtth counterpart manc3ers at the corporate (off-site)
EOC.
This individual reports to the Director of Corporate (offsite)
Emergency Operttions.
Manager of Control Room Operations (Shift Supervisor)
Location: CR Function: Responsibility for the safe operation of the unit including hnplementation of normal and emergency procedures. This individual reports to the Director of Site Emergency Operations.
Fbnager of on-Site Technical Support Loca tion: TSC Function: Responsibility for the analysis of operations data and the development of plans, procedures, and recommended actions in direct support of the Manager of Control Room Operations. This individual reports to the Director of Site Emergency Operations.
On-Site Manager of Radiological Consequence Assessment Location:
Site Function: Coordination of on-site and of f-site radiological monitoring teams, assessment of on-site and off-aite radiological conditions, and recommendation of protective actions.
This individual reports to the Director of Site Emergency Operations.
On-Site Manager of External Communications Location:
Site Func tion: Coordination of all communication between the near-site EOC and the corporate (off-site) EOC and the designated federal, state, and local emergency operations centers. This individual reports the Director of Site Dnergency Operations.
Fbnager of on-Site Resources Location:
Site Function: Coordination of requests for support of personnel assembled in the on-site resources center.
This individual reports to the Director of Site Emergency Operations.
. Manager of Site Engineering Support Location:
Site Function: Coordination of requests for site engineering support. This individual reports to the Director of Site Emergency Operations.
Manager of Site Security Location: Site Function: Direction of site security personnel.
This individual reports to the Director of Site Emergency Operations.
It is emphasized that the above-proposed method was selected as a result of several site-unique characteristics.
One of the more significant features is that the site is composed of one operating BWR, one operating PWR, and one PWR under construction.
There will be intervals of time when in excess of 2,000 individuals will be present.
There exist several spatial limitations within the existing plant security boundary.
The distinction of the TSC priority of bringing the aff ected unit to a safe shutdown condition, and the EOC priority of minimizing the impact on the site as a whole and on the public, takes on additional significance when considera-tion is given to the unique characteristics of the Millstone site.
All other Emergency Response Centers as discussed in Reference (1) remain unchanged, except for the proposed plan to upgrade the Unit No.1 and Unit No. 2 control room video systems.
The control rooms are presently equipped with black and white closed-circuit video systems for viewing the control panels from the Technical Support Centers and the Short-Term Emergency Operations Centers.
In designing these systems, consideration had been given to providing color video equipment, primarily so that indicating lights of various colors would be distinguishable.
However, several complications associated with the upgrading process have been identified. Due to the desired relatively low lign*.ing level on the control boards, a particularly sensitive camera / lens / aperture arrangement must be used to obtain reasonable color resolution.
Presently available equipment does not have the required dynamic range to accommodate both this low ambient lighting level and brighter light sources such as annunciator window lights, witho-t saturating the system.
NNECO's evaluation has determined that the present black and white TV systems are adequate such that the purposes of the center can be fulfilled.
Plans for long-term knplementation for the TSC's and EOC will be revised in this manner.
We trust you find the above information sufficient to concur with our determination that our proposals are responsive to the NUREG requirements. To support the extremely compacted schedule for implementation, your prompt written concurrence to that ef f ect is respectfully requested.
Very truly yours, NORTHEAST NUCLEAR ENERGY COMPANY b 74 fld
