SUBJECT: WATTS BAR NUCLEAR PLANT - INTEGRATED INSPECTION REPORT
05000390/2022003 AND 05000391/2022003
Dear Jim Barstow:
On September 30, 2022, the U.S. Nuclear Regulatory Commission (NRC) completed an
inspection at Watts Bar Nuclear Plant. On October 24, 2022, the NRC inspectors discussed the
results of this inspection with Mr. Anthony Williams and other members of your staff. The results
of this inspection are documented in the enclosed report.
No findings or violations of more than minor significance were identified during this inspection.
The Regional Administrator has authorized staff to use IP 50001, Steam Generator
Replacement Inspection, to inspect Watts Bar Unit 2 Steam Generator Replacement because
the steam generator replacement inspection is an infrequent inspection and outside of the
routine reactor oversight program (ROP) baseline inspections.
This letter, its enclosure, and your response (if any) will be made available for public inspection
and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document
Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public
Inspections, Exemptions, Requests for Withholding.
Sincerely,

on July 28. On August 2, 2022, Unit 1 was briefly reduced to 70 RTP to repair D common
station service transformer (CSST) and returned to 100 RTP on the same day. The unit
remained at or near RTP for the entire inspection period.
Unit 2 began the inspection period at Mode 1 following the refueling outage and returned to 100
RTP on July 5, 2022. On August 2, 2022, Unit 1 was reduced to 70 RTP to repair D CSST and
returned to 100 RTP on the same day. The unit remained at or near RTP for the entire
inspection period.
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in
effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with
their attached revision histories are located on the public website at http://www.nrc.gov/reading-
rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared
complete when the IP requirements most appropriate to the inspection activity were met
consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection
Program - Operations Phase. The inspectors performed activities described in IMC 2515,
Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of
IPs. The inspectors reviewed selected procedures and records, observed activities, and
interviewed personnel to assess licensee performance and compliance with Commission rules
and regulations, license conditions, site procedures, and standards.

93100 - Safety-Conscious Work Environment Issue of Concern Followup
Safety-Conscious Work Environment Issue of Concern Followup (1 Sample)
(1) NRC qualified safety culture assessors performed a limited assessment of the safety
conscious work environment (SCWE) in the Chemistry Department at Watts Bar in
accordance with IP 93100, Safety Conscious Work Environment Issue of Concern
Follow-up. The objectives of the assessment were to: (1) determine whether actions
taken by Tennessee Valley Authority improved the work environment in the Chemistry
Department; (2) determine if employees are currently reluctant to raise safety or
regulatory issues; and (3) determine if employees are currently being discouraged
from raising safety or regulatory issues.
The team interviewed all available employees (25) from the Chemistry and Radiation
Protection Departments, which consisted of technicians, chemists, supervisors,
managers, and the employee concern program (ECP) manager. In general, at the
time of the inspection, the team determined that many employees in the chemistry
department are hesitant to raise safety concerns through multiple avenues out of fear
of retaliation or have the perceptions that nothing will be done with their concerns if
they do raise them. The team noted that some will not use the ECP; some are
hesitant to talk to the NRC; and while they are sometimes willing to write condition
reports (CRs), they have an overall perception that nothing will be done with the CRs
once they write them. The team heard that the amount of turnover and churn among
the staff and supervisors is causing tremendous strain on the organization. The team
also reviewed TVAs responses to the GLINT assessment, the USA Alliance nuclear
safety culture assessment and responses to NRC Requests for Information, which all
identified the Chemistry Department as an area of concern and have determined that
corrective actions are new and have not yet been effective at fixing the previously
identified work environment issues within the Chemistry Department. In addition, the
team determined that the corrective actions are not comprehensive enough to
address the work environment issues within the department.
The NRC determined that there is a chilled work environment in the Chemistry
Department, meaning individuals are hesitant to raise nuclear safety concerns for fear
of retaliation and perceive that Chemistry supervision is retaliating against chemistry
employees for bringing up concerns. The NRC reviewed the NRC allegation manual
guidance, Section 5.2.i.6(a)(2), to determine if a chilling effect letter (CEL) is
warranted at this time. The NRC concluded that the CEL is not appropriate at this
time because the licensee had recently implemented corrective actions and is still
evaluating the effectiveness of corrective actions. The NRC has requested the
licensee respond to the NRCs assessment results and implement appropriate
corrective actions.
