STANDARD REVIEW PLAN UPDATE AND DEVELOPMENT PROGRAM (SRP-UDP)
Purpose:
To provide the Commission with information on the restructuring of the SRP-UDP.
To establish an interim SRP based upon data and systems currently available and established by the SRP-UDP.
Summar_y:
This paper informs the Commission of the restructuring of the SRP-UDP.
Among the highest priority work at this time for the Office of Nuclear Reactor Regulation (NRR) are the ongoing reviews for advanced reactor certification.
Due to the pressures of current schedules, NRR re-sources have boon concentrated on these reviews.
This paper provides a summary of the current status and plans for the SRP-UDP effort, including ongoing activities to maintain the SRP current and describes the practicality of an interim SRP.
A final project completion date cannot be projected at this time.
Backaround:
The NRC developed the SRP in 1975 to provide guidance to staff reviewers in performing safety reviews of applications to construct or operate nuclear power plants.
In 1981, the staff revised the entire SRP and published it as NUREG-0800.
Since 1981, the NRC has made considerable changes in the regulation of the CONTACT:

nuclear power reactor industry.
Consequently, an updated SRP for the review of future reactor applications was needed to reflect existing agency requirements and guidance and to add new review criteria to accommodate the unique technology or the unique application of existing technology in future reactor designs.
In SECY-91-161, " Schedules for the Advanced Reactor Reviews and Regulatory Guidance Revisions," May 31, 1991, the staff discussed in part the revision effort for the SRP.
In the paper, the staff committed to produce supple-monts to the 1981 revised SRP in parallel with the conduct of current and future reactor design reviews.
This would result in an updated SRP that incorporates information from the advanced reactor reviews.
The staff also committed to complete the program, including full automation of the SRP, in FY 1995.
The SRP-UDP was established in the spring of 1991 to accomplish these goals and was subsequently reviewed and approved by the Senior Contract Review Board.
In a memorandum of November 18, 1991, the Executive Director for Operations (EDO) requested that the Chairnan approve a commercial contract to provide technical assistance in ravising the SRP.
In the memorandum, the EDO discussed the SRP-UDP in detail and its resource implications, estimated at $19,400K.
In his responso of December 13, 1991, the Chairman approved the use of-a commer-cial contractor and also stated his concern that the SRP had been allowed to becomo " outmoded."
In this regard, the Chairman stated, "The staff should ensure that when this project is completed in FY 1997, adequate agency resources and procedures are in place to review and revise the SRP as needed at least annually."
D1EEMEEl2D:
The SRP-UDP commenced in March 1991.
A technical assistance contract-for approximately $20,000K was established to provide program support.
By the fall of 1992, NRR priorities and schedule pressures in regard to advanced reactor certifica-tion reviews dictated a reevaluation of the SRP-UDP goals.

The Coumissioners 3
The following discussion outlines a redirection in the program and discusses activities that have been completed, activities for which work will continue, and activities not scheduled for completion until NRR resources are available.
The current SRP combined with the SRP-UDP completed work, defined below, form an interim SRP.
The staff can use the intcrim SRP to review future reactor designs.
The following items have been completed:
A state-of-the-art full-relational database (MDB) that allows the staff to retrieve SRP information and maintain the data up to date was installed on the NRR AUTOS LAN in February 1992.
A text retrieval system that provides the capability to conduct a full text search of generic regulatory documents was installed on the NRR AUTOS LAN in March 1992.
Information from generic regulatory documents applicable to the SRP has been identified and sorted by SRP section and loaded in the MDB in November 1992.
This information constitutes the essential source data for revising the SRP, but has not been reviewed for consistency with the current SRP or for conflicts betwoon regulatory documents, nor has it been combined into well-defined issues that would constituto required or recommended changes to SRP sections.
A list of codes and standards found in regulatory documents will provide a starting point for the staff to compare existing codes and standards references to newer codes and standards editions for future design applications.
The list will be published as NUREG/CR-5973 and is available to the staff in dBase format.

Procedures to be used by contractors and staff have boon developed that ensure a consistent approach and methodology in revising and developing SRP sections.
The SRP-UDP Implementing Procedures Document was published in May 1992 as NUREG-1447.
Scheduled work and staff activities include the following:
Complete a pilot program in accordance with NUBEG-1447 that will revise two SRP nections, the compressed air system and system quality group classification.
The pilot should be completed in the second quarter of FY 1993.
Revise the procedurcs document, NUREG-1447, to incorporate lessons learned from tha pilot programs.
This revision should be completed in the summer of 1993.
Complete a comparison of the latest codes and standards to the codes and standards referenced in the existing SRP and regulatory guides.- Expected completion date is FY 1994.
Identify (but not incorporate) SRP applicabic information from design certification reviews for inclusion in the SRP.
The initial designs to be addressed are the advanced boiling water reactor and the System 80+.
Other designs will be addressed once the final safety evaluation reports are completed.
Ensure program data remain current, as new generic regulatory documents are issued and new version of codes and standards are pre-pared.
This task will be part of ongoing maintenance for this program.
When the SRP-UDP is completed, the maintenance program will ensure that the SRP is updated annually.
Continue, at a reduced rate, developing required or recommended changes to the SRP.
The staff will process the sourca data (SRP
I The commissioners 5
applicablo information loaded in the MDB) by (1) reviewing it for consistency with the current SRP, (2) reviewing it for conflicts between regulatory documents, and (3) combining the information into well-defined issues that will be analyzed (at a later time) for inclusion in the SRP.
The results of those activities will be added to the MDB to enhance the usefulness of the interim SRP for future design reviews.
Subsequent activition in revising the SRP, which include developing SRP revisions and automating the SRP, are not currently scheduled for com-plation and will be completed as prioritics dictate.
Specifically, the following activities do not have a completion date:
Once developed, the abcyo "well defined issues," would be analyzed from a technical standpoint for the desirability or necessity of including them in the SRP.
The argument developed by this analysis would form the technical rationale for the SRP change and be included in the MDB and the SRP.
Revising SRP sectior.7, including developing and incorporating technical rationale for existin~ staff acweptance criteria (new acceptance criteria technical rationale would be developed by a method described in the previous bullet).
Incorporating specific design certification information in the SRP, including the preparation of supplements to the current SRP in parallel with current and future design reviews for evolutionary and passive plants.
Publishing and incorporating public comments into the SRP.
Rescutce Imnlications:
The staff resource implications for this program in the current Five Year Plan estimate for FY 1993
e I
The commincioners 6
are 15 staff full timo equivalents (FTEs) ; this would be reduced to 6 FTEs in the redirected SRP-UDP.
With 6 staff FTEs, coordination of maintenance and reduced program activities (as described above) could continue.
Program maintenance is a contractor supported activity with review and acceptance by the staff.
As available, additional technical division FTEs could support the program to facilitate its completion.
The cost of the SRP-UDP from FY 1991 through FY 1992 was approximately $6,200K.
The projected FY 1993 contract cost orig $nally was set at $3,745K.
This is being reduced to approximately $2,100K to support the interin SRP and provide maintenance through the remainder of FY 1993.
The remaining staffing and funds for FY 1993, approximately 9 FTE and $1,645K, are being applied to higher priority HRR work.
The following SRP-related resources are identified in the FY 1993-1997 Five-Year Plan: 18 FTE and
$2,270K in program support for FY 1994 and 15 FTE and $1,910K in program support for FY 1995.
Resources for the SRP effort will be addressed during the next update of the Five-Year Plan.
Contractor maintenance costs for FY 1994 through FY 1996 would be approximately $1,100K per year.
Scheduljng:
The interim SRP is currently available.
A final project completion dato cannot be projected at this time.
