Implementation of a Smarter Fuel Cycle Inspection Program Background and Objective:
On April 26, 2019, the U.S. Nuclear Regulatory Commission (NRC) established a working group to conduct a holistic assessment of the fuel cycle inspection program to improve the effectiveness and efficiency of the program (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19074A139).
In consideration of the agencys focus on transformation and innovation, the primary objective of the working group was to integrate risk-informed insights to ensure that the appropriate focus is applied to those areas most important to safety. The working group, composed of experienced staff from the Office of Nuclear Material Safety and Safeguards (NMSS) and Region II, used both domestic and international operating experience, risk insights, inspection data, and lessons learned to assess the program and develop recommendations for enhancement.
Recommendations:
By memorandum dated March 18, 2020 (ADAMS Accession No. ML20073G659), the working group proposed a series of changes to the fuel cycle inspection program, including:
(1) modifications to inspection frequencies and resource estimates associated with completion of inspection procedures, (2) modifications to inspection procedures to reduce overlaps, and (3) modifications to inspection frequencies of inspection procedures for facilities with an NRC--approved corrective action program.
Specifically, the working group issued the following six recommendations in the development of a smarter fuel cycle inspection program:
- 1) In-depth assessment of the scope of resident inspector guidance and its referenced procedures as part of the implementation phase of this initiative. The assessment should consider potential changes to ensure the scope of the resident inspector program is focused on the areas that provide the greatest safety benefit and should also consider recommendations provided by external stakeholders. Based on this review, further adjustment of inspection activities between regional and resident inspector activities may be recommended.
- 2) A reduction in the frequency of inspection to Tier 2 and Tier 3 inspection technical areas for licensees with an NRC-approved CAP.
- 3) The following inspection frequencies and hours based on the tier ranking of each of the inspection areas.
o Tier 1 areas - Annual inspection frequency and a minimum of 90 hours0.00104 days <br />0.025 hours <br />1.488095e-4 weeks <br />3.4245e-5 months <br /> o Tier 2 areas - Biennial inspection frequency and a minimum of 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> o Tier 3 areas - Triennial inspection frequency and a minimum of 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> with a range of hours to accommodate for any necessary adjustments on inspection scope based on the length of time between inspections Enclosure
- 4) A revision to Inspection Manual Chapter (IMC) 2600 to include an acceptable variance of plus or minus 10 percent in the core hours. In addition, language on the acceptable variance should be included in the resources estimate section for each inspection procedure.
- 5) Incorporation of changes described in Section d. of the report (ADAMS Accession No. ML20073G659), along with the marked-up version of the Appendix B to IMC 2600 with the recommended hours and frequencies for each area of the core inspection program.
- 6) Formalizing into the inspection program the results of the Operating Experience Program and the Fuel Cycle Inspection Assessment Program to determine, on a frequent basis, if changes to the core inspection program are needed.
Approval of Recommendations and Staff Plan for Implementation:
By memorandum dated March 18, 2020 (ADAMS Accession No. ML20077L247), the Director of Division of Fuel Management (DFM) of NMSS endorsed the working groups recommendations to build a smarter fuel cycle inspection program, with completion of updates to inspection guidance by December 2020, and implementation of inspection activities starting in calendar year 2021.
On August 26, 2019, the staff developed an Implementation Plan (ADAMS Accession No. ML20189A064), with the objective to implement the working groups recommendations to enhance IMCs and inspection procedures (Ips) related to fuel facilities, as endorsed by the DFM Director on March 19, 2020. Specifically, the staff focused its initial implementation efforts on Recommendations 1 - 5.
The staff deferred the implementation of Recommendation 6 to calendar year 2021.
Implementation of Recommendations:
To date, the staff revised 91 percent of the fuel cycle program guidance, including all procedures to support scheduled inspections in the first quarter of 2021. Four training sessions were conducted to familiarize inspection staff with the revisions to the procedures and to ensure common understanding of any new and revised guidance. The training sessions were recorded for future use and made available to the staff as a reference.
The remaining 9 percent will be issued in early 2021 or retired by late 2021.
The following procedures have been issued for use:

Specifically, for those functional areas that will receive two inspections in one year, the frequency of inspections and estimated resources were revised to clarify the estimated resources per inspection.
Three procedures will be retired in 2021, the contents of which have already been incorporated into other documents:

Where appropriate, increases or decreases greater than 10 percent shall be approved by a Branch Chief, as described in IMC 2600 Section 7.02.
5 Incorporation of changes described in The changes described in Not Applicable Section d. of the report (ADAMS Section d. of the report, Accession No. ML20073G659), along related to inspection with the marked-up version of the frequency, resource Appendix B to IMC 2600 with the estimates, plant recommended hours and frequencies operations, criticality for each area of the core inspection safety, fire protection, program material control and accounting, radiation protection, environmental protection, waste management, transportation, maintenance and surveillance, emergency preparedness and plant modifications were completed with revisions to IMC 2600, Appendix B, all IPs and applicable IMCs.
The changes described in Section d. of the report related to inspection preparation and documentation were evaluated and where appropriate, incorporated into revisions to IMC 2600, IMC 0616 and internal inspection guidance. Specifically, the recommendations were addressed as follows:
- Guidance on increasing the use of technology to aide in document reviews and the efficient review of licensing documents was added to IMC 2600.
- The staff considered a range of variables involved in inspection preparation and documentation including the varying experience of inspectors, inspection type, facility type, the complexity of issues and potential event follow up, and determined that expectations for the appropriate depth and time for inspection preparation and documentation are sufficient. Additionally, significant deviations for inspection preparation and documentation will continue to be managed at the supervisor level and no further action is needed.
- The staff implemented updates to the Reactor Program System and expanded the use of Inspection Scheduling, Tracking and Reporting (ISTAR). These updates standardize inspection documentation and report generation. IMC 0616 was revised to include tables, fields and instructions required to use ISTAR to generate reports.
The staff expects these updates to result in reduced inspection documentation time.
- Appropriate IPs were revised to include additional guidance on sample selection, and internal guidance is being used to ensure inspection preparation is focused on items of regulatory significance to the specific licensee or facility type.
