SUBJECT:
ASSESSMENT FOLLOW-UP LETTER FOR GRAND GULF NUCLEAR STATION
Dear Mr. Larson:
As a result of our continuous review of plant performance the NRC updated its assessment of Grand Gulf Nuclear Station. The NRC's evaluation consisted of a review of performance indicators and inspection results. This letter informs you of the NRC's assessment and its plans for a future inspection at your facility. This letter supplements, but does not supersede, the annual assessment letter issued on March 1, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No.
ML17059D517).
The NRC's review of Grand Gulf Nuclear Station identified that the Unplanned Power Changes Per 7,000 Critical Hours performance indicator has crossed the Green-to-White threshold. The performance issues included in this performance indicator were associated with three unplanned downpower events that occurred in the second quarter of 2016 due to operator actions to reset turbine stop valves, an unplanned downpower and shutdown required by technical specifications that occurred in the third quarter of 2016 due to a failure of residual heat removal subsystem A, and an unplanned downpower that occurred in the first quarter of 2017 due to condensate booster pump seal degradation.
The NRC determined the performance at Grand Gulf Nuclear Station remains in the Regulatory Response Column of the Reactor Oversight Process Action Matrix following a second White performance indicator input in the Initiating Events cornerstone beginning in the fourth quarter of 2016. Therefore, the NRC plans to conduct a supplemental inspection in accordance with Inspection Procedure 9500 1 , "Supplemental Inspection Response to Action Matrix Column 2 Inputs" due to the Uplanned Power Changes Per 7,000 Critical Hours performance indicator.
Additionally, the NRC previous ly indicated our intent to perform a sup lemental inspection in accordance with Inspection Procedure 95001 due to the Unplanned Scrams Per 7000 Critical Hours performance indicator crossing the Green
-to-White threshold in the third quarter of 2016 as indicated in a letter sent on November 8, 2016 (ADAMS Accession No. ML16313A169). As of the date of this letter we have not been notified that you are ready for this inspection. The objectives of the supplemental inspection are: (1) to assure that the root causes and contributing causes of significant performance issues are understood, (2) to independently UNITED STATES NUCLEAR REGULATORY COMMISSION REGION IV 1600 E. LAMAR BLVD ARLINGTON, TX 76011
-4511 E. Larson 2 assess and assur e that the extent o f condition and extent o f cause of significant performance issues ar e identified, (3) to assur e that corrective actions tak en to address and preclude repetition of significant performance issues are prompt and effective, and (4) to assur e that corrective plans di rect pr ompt ac tions t o e ffectively addr ess and pr eclude r epetition of s ign ificant performance issues. This i nspection will be scheduled after y ou notify t he N RC writing of y our readiness. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRC's "Rules of Practice," a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading
-rm/adams.html (the Public Electronic Reading Room).
Please contact Jason Kozal at 817-200-1144 with any questions you have regarding this letter.
