NUCLEAR DATA LINK (NDL) MANAGEMENT PLAN
Purpose:
To respond to the Commission's request that the specifications for the Nuclear Data Link be developed (July 15, 1980 memorandum from Chilk to Dircks) and to seek Commission approval to proceed with a prototype NDL according to the management plan recommended by the s ta f f.
Background:
The staff has previously provided the Commission with information and plans regarding the Nuclear Data Link concept and implementa-tion in SECY 80-35,80-35A, and 80-326.
These papers were presented at a Commission briefing ut Open Meetings on February 7, 1980, May 15,1980, and July 11, 1980, respectively. As a result of the last briefing, the staff was instructed to develop NDL system specifications for open bidding purposes and the selection of contractors to implement the selected system.
This paper is to update the Commission on various actions and activities related
' to the NDL and request further guidance regarding the implementa-tion of the NDL.
Discussion: At the last meeting on the NDL, the Commission also discussed the publication of NUREG-0696, " Functional Requirements for Safety Parameter Display, Technical Support Center, Emergency Operations Facility and Nuclear Data Link," which provides guidance to licensees and other emergency preparedness planners to design an integrated emergency resource capability, including the NDL. This document was published as a final report during February 1981.
The NDL section of NUREG-0696 is provided in Enclosure 1.
In addition, to obtain an independent evaluation of the NDL approach and specifications developed by Sandia for the NRC, the staff requested the Research Triangle Institute (RTI) and the National Aeronautics and Space Administration (NASA) to review the published work available on the NDL concept developed by Sandia and the staff and comment on the technical aspects of the concept.
The NASA report is Enclosure 2 and the RTI report is Enclosure

'The Commissioners -
difficult to verify the Sandia cost estimates but felt that projected NRC costs indicated were not unreasonable.
These reviews have provided cogent comments which help to refine system design ard indicate areas of possible cost savings.
I have instructed the staff to prepare for separate transmission to the Commission, a memorandum discussing the comments received from NASA.
It should be emphasized that with respect to scheduling the NDL, implementatica of the data acquisition system for the Technical Support Center (TSC), Emergency Operations Facility (EOF), Safety Parameter Display System (SPDS), and the NDL must be in parallel.
It appears low that these necessarily concurrent actions will result in the initial operational capability of the NDL being achieved in about fou; years, at the earliest, from the time the Commission instructs the staff to move forward with the recommended management plan to implement the NDL.
Additional time may be required depend-ing on the course of action chosen.
This paper sets forth alternative program management plans that were evaluated by the staff. The division of responsibilities under these plans, the estimated NRC staff needed under each plan, and advantages and disadvantages of the alternatives are presented in Enclosure 4.
Program Management Concepts The following program n.anagement plans have been considered for NDL implementation.
Plan A:
NRC Program Office / Contractor Implementation Under this plan, NRC would establish a Program Office and select, via competitive bidding, a contractor. The Request for Proposal could allow a range of implementation alternatives to encourage potential contractors to adapt existing technology and equipment to the NDL functional needs.
Plan B:
NRC Program Manager /Sandia Imolementation This plan would be an extension of the NRC/Sandia working arrange-ment now in use for development of the NDL functions.
Under this plan, Sandia would be assigned responsibilities bcth as Systems Integrator and prime system implementor. Sandia's services would be obtained through the established NRC/ DOE agreement and Sandia would in turn contract for certain goods and services Plan C:
NRC Program Manager /0utside Technical Integrator Manages Program /
Systems Contractor Under this plan, as in plan B, many of the tasks traditionally associated with an NRC Program Office would be assigned to another
The Commissioners Organization (in this case, the Technical Integrator).
Impl e-mentation would be carried out via competitive bidding conducted by the NRC with assistance in evaluation by the Technical Integrator.
Once let, the contract or contracts would be managed by the Technical Integrator.
Potential Technical Integrators could include a National Laboratory, a not-for-profit organization, or an indo?.r, organization competitively selected.
Concl usion :
The staf' has compared the advantages and disadvantages of the variour a'ternatives.
(See Enclosure 4.)
None of these arran;emr.its has a clearly preeminent advantage over the others.
However the staff believes that plan A or C should be selected.
There auld be some delay in implementing the program using plan A or C over use of plan B.
This is tolerable, however, in view of the major disadvantages of plan B even though the delay would put the implementation somewhat beyond the parallel development of the other emergency response facilities.
A detailed description of the implementation of the NDL in accordance with plan C is included in the Technical Integrator RFP (Enclosure 5) prepared by Sandia.
The staff believes that plan C may be more advantageous than plan A because there would be a much more limited staff buildup.
If plan C is selected, several alternatives for the Technical Integrator for implementing the NEL should be considered.
Sandia would be a possible candidate for Technical Integrator sirce Sandia has acquired a great deal of expertise in developilg the NDL concept and thus costs implicit in transfer of system cogni-zance and other planning would not be incurred.
However, the staff believes that a fresh perspective on the problem may be desirable.
The staff has broached with NASA the idea of NASA assisting NRC in managing the NDL implementation.
NASA has not been encouraging, but high-level negotiations might bring forth a willingness to n, st NRC in this project.
If NASA would accept designation as Technical Integrator, they have indicated that they would have to, in turn, select one of their laboratories, such as the Jet Propulsion Laboratory, to perform the task. We believe that project costs would be comparable to the same scheme using Sandia as Technical Intagrator.
The designation of any government or not-for-profit entity as systems manager would involve similar costs and schedule consid-erations. Selection of a firm from private industry as Technical Integrator is also a possibility.
It would be preferable that, if a private contractor is selected as Technical Integrator, it should be excluded from furnishing hardware, or other operational requirements for the final implementation or the concept would in some respects revert to plan A with the NRC needing to per-form all tasks associated with procurement.
The Commissioners NRC could determine the availability of companies to be employed as Technical Integrator by publishing a request for expressions of interest in the appropriate trade press.
Responses could then be evaluated and a determination could be made of the method of selecting the Technical Integrator.
Recommendatio n: That the Commission:
Instruct the staff to move forward under plan C to implement a prototype of the NDL using the approach and specifications developed by Sandia and appropriately modified to reflect the cogent comments of RTI, NASA, and internal review.
Instruct the staff that the NDL prototype is to be implemented between the NRC operations center and two facilities (one BWR and one PWR) in the following steps:
(a) Proceed to solicit expressions of interest from profit and not-for-profit entities for the Technical Integrator role.
Based on these submittals proceed to select an entity for the Technical Integrator role.
(b) Proceed with other NDL tc u. by solicitation for bid through the competitive process once the Technical Integrator is chosen to manage the contracted tasks.
