| SUBJECT: WATERFORD STEAM ELECTRIC STATION, UNIT 3 - NOTIFICATION OF NRC
| |
| TRIENNIAL HEAT EXCHANGER/HEAT SINK PERFORMANCE INSPECTION
| |
| 05000382/2021003 AND REQUEST FOR INFORMATION
| |
| Dear Mr. Ferrick:
| |
| The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff
| |
| will conduct the triennial portion of the heat exchanger/heat sink performance inspection at
| |
| Waterford Steam Electric Station, Unit 3 from August 16 - 20, 2021. The onsite phase of the
| |
| inspection will consist of one reactor inspector from the NRCs Region IV office for one week.
| |
| The inspection will be conducted in accordance with NRC Inspection Procedure (IP) 71111,
| |
| Attachment 07, Heat Exchanger/Heat Sink Performance, dated January 1, 2021.
| |
| The objectives of the inspection are to verify that: 1) any potential heat exchanger deficiencies
| |
| which could mask degraded performance are identified, 2) any potential common-cause heat
| |
| sink performance problems that have the potential to increase risk are identified, and 3) the
| |
| licensee has adequately identified and resolved heat sink performance problems that could
| |
| result in initiating events or affect multiple heat exchangers in mitigating systems and thereby
| |
| increase risk.
| |
| To minimize the impact the inspection has on the site and to ensure an efficient inspection, we
| |
| have enclosed a request for documents needed for the inspection. It is important that these
| |
| requests are fulfilled as completely and accurately as possible to minimize any additional
| |
| requests during the preparation week or during the onsite inspection. The documents have
| |
| been divided into three groups.
| |
| * The first group lists information necessary for our initial inspection scoping activities.
| |
| This information should be available to the lead inspector no later than July 5, 2021. By
| |
| July 12, 2021, the lead inspector will communicate the initial selected set of 2-4 risk
| |
| significant or safety-related heat exchangers and/or heat sinks.
| |
| * The second group of documents requested includes those items needed to support our
| |
| in-office preparation activities. This set of documents, including the calculations
| |
| associated with the selected heat exchangers and/or heat sinks, should be available no
| |
| later than August 2, 2021. This information should be separated for each selected
| |
| | |
| J. Ferrick 2
| |
| component, especially if provided electronically. Note that the inspector(s) may identify
| |
| additional information needed to support the inspection during this week and will
| |
| communicate those requests as soon as practicable.
| |
| * The third group of documents requested includes the additional documentation identified
| |
| during in-office preparation activities as well as other resource requests necessary to
| |
| support our onsite inspection activities. The additional information or resources should
| |
| be available throughout the week of onsite inspection activities beginning on August 16,
| |
| 2021.
| |
| All requested documents are to be for the time period from the onsite inspection period back to
| |
| the last triennial heat exchanger/heat sink performance inspection. If nothing addressing a
| |
| request was done in that time period, then the request applies to the last applicable document.
| |
| If a request does not apply for any heat exchanger/heat sink sample, no response is necessary.
| |
| Include all attachments to the requests, especially corrective action program documents.
| |
| We have discussed the schedule for this inspection with your staff and understand that our
| |
| regulatory contact for this inspection will be Mr. Remy Devoe of your Licensing Organization. If
| |
| there are any questions about this inspection or the documents requested, please contact the
| |
| lead inspector, Wayne Sifre, by telephone at 817-200-1193 or by e-mail at
| |
| Wayne.Sifre@nrc.gov.
