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. | |||

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

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
