Significance Determination Process (SDP)
Timeliness Review David Aird, NRC Reactor Assessment Branch (IRAB)
ROP Public Meeting May 26, 2022 1
Why are we performing this review?
- IRAB staff conducting a review of SDP timeliness to assess the past several years of missed metrics
- Goal is to identify any common themes, trends, shifts in philosophy, unintended consequences of changes, etc.
- Near term action
- Outreach to internal and external stakeholders
- Backstop for completion of review is end of CY2022
- Output will be a publicly-available memo documenting the scope of the review and any proposed changes to the metric or the SDP (see IMC 0609) 2
SDP Timeliness - Background
- Metric changed in CY2020 from separate 120-45-90 metrics to an overall 255-day metric
- Metric calculation was changed from a percentage to a discrete count
- Self-assessment metric is on CY, other metrics (e.g., Congressional Budget Justification) are on FY
- The metric was determined to be Yellow in CY2020 and CY2021
- ROP Self-Assessment results are located at the following link:

SDP Process Overview
- Figure at left from IMC 0609, Attachment 5
- At present, the only reported metrics are the overall 255-day SDP and the 45-day inspection report issuance (see IMC 0307, Appendix A, section 02.01)
- The previous 120-day inspection timeliness and 90-day SDP timeliness metrics are monitored for information only.

History of SDP metric Then (2000) Now (2020 to present)
SDP-10 SDP Timeliness Definition: For each quarter, count the number of inspection findings that are either:
- 1) in the SERP process, were open for any portion of that quarter, and are more than 90 days from the exit meeting date
- 2) received by an NRR technical branch for SDP assistance, and are more than 90 days from the exit meeting date or the date received by that branch, whichever is earlier
- 3) otherwise documented in an inspection report as an unresolved item, were not counted in either of the above categories, and are more than 90 days from the
- The above definition is found in IMC 0307, exit meeting date. Appendix A Criteria: All SDP results that are counted per the criteria
- The metric definition changed several times above should be finalized within 90 days of the exit (iterative) since CY2000 meeting.
