3 Accordingly, the following change is hereby made:
- 1. The increase in ceiling is a result of additional effort to cover Task 2, the 50.46c portion of the database and for Task 3. The work required for Task 3 was underestimated. The identification of the 50.46 reports was more complex than originally anticipated due to insistencies in the way the reports were submitted (e.g., different titles, packages, categorization, etc.). Additionally, determining what information to include in the database from the reports required more effort as a result of how each licensee documented the information. Therefore, the attached Statement of Work (SOW) titled NRC-HQ-20-16-T-0007 MOD 5 SOW hereby replaces Section C, Descriptions/Specifications/Statement of Work under this task order.
- 2. Section NRCB040A CONSIDERATION AND OBLIGATIONCOST-PLUS-FIXED-FEE ALTERNATE I is replaced in its entirety.
NRCB040A CONSIDERATION AND OBLIGATIONCOST-PLUS-FIXED-FEE ALTERNATE I (a) The total estimated cost to the Government for full performance of this contract is

PROJECT TITLE 10 CFR 50.46 Reporting Database Development 2.
BACKGROUND Current 10 CFR 50.46 Rule 10 CFR 50.46, Acceptance criteria for emergency core cooling systems for light-water nuclear power reactors, requires that each boiling or pressurized light-water nuclear power reactor fueled with uranium oxide pellets within cylindrical zircolay or ZIRLOTM cladding must be provided with an ECCS that must be designed so that its calculated cooling performance following a postulated loss-of-coolant accident conforms to the criteria set forth in 10 CFR 50.46(b) and ECCS cooling performance must be calculated in accordance with an acceptable evaluation model and must be calculated for postulated loss-of-coolant accidents of different sizes, locations, and other properties sufficient to provide assurance that the most severe postulated loss-of-coolant accidents are calculated.
10 CFR 50.46(a)(3)(ii) governs the reporting requirements. It requires that for each change to or error in an acceptable evaluation model or in the application of such a model that affects the temperature calculation, the applicant or holder of a construction permit, operating license, combined license, or manufacturing license shall report the nature of the change or error and its estimated effect on the limiting ECCS analysis to the Commission at least annually and if the change or error is significant, the applicant or licensee shall provide a report within 30 days.
For significant errors and/or changes, 10 CFR 50.46 reports are required to be submitted to the NRC in 30 days. Each year, annual reports are submitted to the NRC that summarize all the errors and/or changes (significant and non-significant) accrued in the previous calendar. Some years there are no errors and/or changes identified for an evaluation model or in the application thereof, while other years there can be many errors and/or changes applied to an evaluation model or in the application thereof. These errors and/or changes can result in penalties or benefits to a licensees analysis of record. The number of errors and/or changes applied to the accepted evaluation models or in the application thereof has become quite large which makes it challenging to ensure that each licensee is applying the applicable errors and model changes to their analyses of record (AOR).
Additionally, many licensees have committed to reanalyze their design basis LOCAs with approved ECCS evaluation models that have implemented model changes to account for fuel pellet thermal conductivity degradation. Thus, the staff expects that many new LOCA analyses will be submitted and it will be necessary to track the analysis results and any model assessments.
Lastly, if the proposed 10 CFR 50.46c Rule gets final approval, the staff expects several additional new LOCA analyses to be submitted and many LOCA analyses to be updated to demonstrate compliance with the new rule.
Proposed 10 CFR 50.46c Rule The proposed 10 CFR 50.46c rule establishes a general, performance-based rule governing ECCS performance for light-water regardless of fuel design or cladding material. This represents a
5 significant change from the existing ECCS regulations which apply to uranium oxide pellets within cylindrical zircolay or ZIRLOTM cladding. Because ECCS requirements must be expressed independent of fuel type, and because ECCS performance ultimately must be based upon maintaining the fuel in the reactor in a safe (analyzed) condition, the proposed 10 CFR 50.46c rule separates the ECCS system performance requirements from the fuel system design.
In the proposed 10 CFR 50.46c rule, the specified performance objectives of the systems, structures, and components of the ECCS are to provide residual heat removal during and following a postulated LOCA. As with the existing regulation, the ECCS performance is demonstrated by acceptable ECCS evaluation models in the proposed rule. Specific performance requirements and analytical limits have been established for fuel designs consisting of uranium oxide or mixed uranium-plutonium oxide pellet with zirconium cladding alloys that account for relatively recent research findings. For other fuel designs, new performance objectives and analytical limits may be necessary. Such objectives and limits would need to take into consideration all the degradation mechanisms and any unique performance features of the particular fuel system.
The proposed rule follows the general regulatory approach of the existing regulation, yet it establishes non-prescriptive, performance-based regulatory language for demonstrating acceptable ECCS performance and determining fuel performance characteristics.
The 10 CFR 50.46c rule requires the similar reporting requirements as the current 10 CFR 50.46 rule, but clarifies the reporting and corrective action requirements in order to resolve recurring issues involving the interpretation of the current regulations requirements. The 10 CFR 50.46c rule distinguishes three possible combinations of reporting criteria based on the following: (1) predicted response, (2) level of significance, and (3) whether the error, change or operation would results in any exceeded acceptance criteria. For each scenario, the proposed rule provides the required actions, reports, and time frame for providing the necessary reports. The new rule maintains the same requirement for annual reporting and requires reporting significant errors in a similar manner.
At a high level the 10 CFR 50.46c reporting rule differs from the existing rule in the following ways. Since the rule allows for specific performance requirements and analytical limits for specific fuel designs, the performance criteria may be different for different fuel types. Thus, it is necessary for the licensee to submit their fuel specific analytical limits, and in particular, analytical limits to preserve cladding post-quench ductility. Additionally, the new reporting rule requires that in the ECCS model error and/or change assessments for equivalent clad reacted (ECR) impacts must be reported in addition to PCT impacts.
This new 10 CFR 50.46c rule has been submitted to the Commission for voting and final approval. If it gets approved, the licensees will be required to submit new LOCA analyses demonstrating that the analyses meet the new requirements. Thus, it will be necessary to track the licensee provided analytical limits, new analysis results, and any model assessments.
6 3.
OBJECTIVE The objective of this project is to modify the existing Core Operating Limits Report (COLR) database to incorporate the current 10 CFR 50.46 Reports and future 10 CFR 50.46c Reports.
The database should have the capability for 10 CFR 50.46 reports to be uploaded for each plant, it should be searchable, and it should be able to generate various reports.
4.
SCOPE OF WORK The Contractor will collect 10 CFR 50.46 reports submitted by all licensees from all of calendar year 2015 and through June 1, 2016. The 10 CFR 50.46 reports are accessible via the NRC Agency Access and Management System (ADAMS). The Contractor will extract data from the 10 CFR 50.46 reports and applicable licensing basis documentation in order to modify the existing COLR database to incorporate the current 10 CFR 50.46 Reports. Note that no Contractor review is necessary for the 10 CFR 50.46 reports.
The Contactor will modify the existing COLR database to incorporate the current 10 CFR 50.46 Reports (and future 10 CFR 50.46 reporting). The database must meet the following requirements:
Database Contents The database should contain the following, at a minimum, for the current 10 CFR 50.46 Rule:
Plant Name Date of AOR ECCS Evaluation Model Analysis of Record (AOR) results for peak cladding temperature (PCT), equivalent clad reacted (ECR) / Maximum Local Oxidation (MLO), and core wide oxidation (CWO)
List of model changes and errors and their associated PCT impact (with associated ML Number)
Sum of the PCT impacts for the model changes and errors Sum of the PCT impacts and AOR PCT Sum of the absolute value of each PCT model change and error An indication if the fuel rod burst for the AOR PCT Case The database should contain all of the above for the future 10 CFR 50.46c Rule and additionally:
Date of Rebaseline AOR (if applicable)
Fuel Type(s)
Fuel Performance Analytical Limit for post-quench ductility (ECR) and, if applicable, PCT List of model changes and errors and their associated ECR impact (with associated ML Number)
Sum of the ECR impacts for the model changes and errors Sum of the ECR impacts and AOR ECR Sum of the absolute value of each ECR model change and error The burnup associated with the limiting case An indication if the fuel rod burst for the AOR ECR Case For both the current and future reports, the sum of the AOR and PCT/ECR impacts should be reported as both their resulting values and as margin to the limit (i.e. for the
7 current rule, if the value of the AOR + PCT impacts was 2100°F, the margin would be 100°F).
Database Capabilities The database should be searchable using the various parameters in the database. The database should be able to generate individual plant reports and reports based on the searched parameters.
The generated reports should be in PDF and Microsoft Excel file types. The data produced in Microsoft Excel report(s) should require minimal NRC staff manipulations in order for the staff to easily filter and sort the data. The database should have the capability to be easily updated and changed with new 10 CFR 50.46 reports in order to incorporate the new reports.

SPECIFIC TASKS Task 1 - Attend a kickoff meeting. Prior to attending the meeting, become familiar with the regulatory framework, the references provided, and the typical format and content of the 10 CFR 50.46 reports. Participate in the meeting to further understand the staff goals for this contract.
Following the kickoff meeting submit a trip report via email that summarizes any decisions reached and any understandings of technical direction given by the NRC staff.
Task 2 - Suggest a format for the database. The database must meet the requirements described in Section 4 and must be able to be integrated into the database the NRC staff currently uses for COLRs (COLR Databased was developed using Microsoft Access). Using sample data, demonstrate the use and performance of the database to the technical point of contact. Coordinate with the technical point of contact to establish an acceptable design for the database.
Task 3 - Identify and upload the 10 CFR 50.46 reports required in Section 4 to the database and harvest the necessary data from the reports and applicable licensing basis documentation.
Coordinate with the technical point of contact to ensure that all the 10 CFR 50.46 reports were identified and that the correct data is being incorporated into the database.
Task 4 - Develop guidance outlining the use of the database.

REQUIRED LABOR CATEGORIES/ESTIMATED LEVEL OF EFFORT The contractors team should include expertise in the following areas:
10 CFR 50.46 Requirements
10 CFR 50.46c Requirements (Future Rule)
Microsoft Access Database Development The estimated level of effort in professional staff hours apportioned among the tasks by labor category is shown in the table below. The estimated is advisory only and not to be considered as the sole basis for the development of the staffing plan.
Additional hours have been added to FY18. The hours are to cover Task 2, the 50.46c portion of the database. This was put on hold until new Commissioners were appointed which occurred at the end of May 2018. Thus, the work on the 50.46c portion of the database has not yet started.
9 Additional funding is needed because the work required for Task 3 was underestimated. The identification of the 50.46 reports was more complex than originally anticipated due to insistencies in the way the reports were submitted (e.g., different titles, packages, categorization, etc.). Additionally, determining what information to include in the database from the reports required more effort as a result of how each licensee documented the information. Therefore, Task 3 was underestimated and additional resources are needed to complete the remaining tasks.
