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,

PLANT STATUS

Unit 1 began the inspection period at 100 percent rated thermal power (RTP). On July 21, Unit

1 was reduced to 98 percent power due to condenser vacuum and returned to 100 percent RTP

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.

(4) Major Structural Modifications to Facilitate SG Replacement (Section 02.03.d)

As required by IP 50001, Section 02.03.d, the inspectors reviewed documentation

associated with the inspection of the SG hold down bolts to verify that any

degradation identified was appropriately addressed.

(5) Containment Access and Restoration of Temporary Containment Opening and

Containment Leakage Testing (Section 02.03.e.)

The inspectors reviewed results of quality control acceptance testing performed on

materials (cement, fine and coarse aggregate, water, and admixtures) selected for

batching of the concrete. The inspectors also reviewed the concrete mix data to

ensure that selected trial mix met concrete design strength requirements, and that

Quality Control (QC) acceptance criteria specified in the procedures for the concrete

were based on the trial mixes.

The inspectors reviewed related concrete testing and sampling activities to assure

compliance with American Concrete Institute (ACI) and American Society for the

Testing of Materials (ASTM) codes.

(6) SG Post-Installation Verification and Testing (Section 02.04)

As required by IP 50001, Section 02.04, the inspectors performed selective

documentation reviews, consistent with the safety significance, of the following

9

areas: snubber pre-service testing; containment leak testing; RCS leakage testing;

SG secondary side leakage testing; and calibration and testing of instrumentation for

both the primary (RCS) and secondary side (feedwater and main steam) systems

affected by the SG replacement.

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.
