UPDATE TO THE TENNESSEE VALLEY AUTHORITY'S RESPONSE TO NRC LETTER CONCERNING A CHILLED WORK ENVIRONMENT FOR RAISING AND ADDRESSING SAFETY CONCERNS AT THE WATTS BAR NUCLEAR PLANT T  (EA-16-061) 
 
==References:==
: 1. NRC letter to TVA, "CHILLED WORK ENVIRONMENT FOR RAISING AND ADDRESSING SAFETY CONCERNS AT THE
 
WATTS BAR NUCLEAR PLANT," (EA-16-061) dated March 23, 2016  2. TVA letter to NRC, "RESPONSE TO NRC LETTER CONCERNING A CHILLED WORK ENVIRONMENT FOR RAISING AND ADDRESSING CONCERNS AT THE WATTS BAR NUCLEAR PLANT," dated April 22, 2016. 
 
The purpose of this letter is to provide an update to Tennessee Valley Authority's (TVA) efforts to address and correct the chilled work environment at the Watts Bar Nuclear (WBN)
Plant. In our response letter dated April 22, 2016 (Reference 2), TVA acknowledged that a work environment inconsistent with TVA core values and behaviors existed. TVA reaffirmed its commitment to ensuring that a healthy nuclear safety culture and healthy safety conscious work environment exist across TVA's nuclear fleet, where employees feel free to raise concerns without fear of retaliation. Our response discussed the initial actions taken, actions in progress and planned future actions. These actions were documented in the TVA Chilled Work Environment Action Plan attached to our April 22, 2016 response letter and in the WBN Corrective Action Program (CAP), and addressed the nuclear safety culture and safety conscious work environment elements and actions in your letter of March 23, 2016 (Reference 1). 
 
The status of these actions is being monitored through assessments, surveys and senior management oversight. Adjustments to the actions have been and will continue to be made based on insights gained.

The chilled work environment action plan and a root cause analysis were initiated beginning in April 2016. The status of the chilled work environment action plan, the root cause analysis results and corrective actions were shared with the NRC at a Public Meeting held on May 24, 2016. Actions were implemented throughout the summer of 2016 and many actions have been completed. As noted previously, the WBN Senior Leadership Team recognized the need to assess and adjust actions to ensure that identified causes were actively and effectively addressed to improve the work environment at Watts Bar.
 
To that end, in August 2016, Watts Bar tasked Conger & Elsea, an independent consulting firm, with providing assessments of the status of the Watts Bar safety conscious work environment, the adequacy and effectiveness of the Chilled Work Environment Root Cause Analysis and associated corrective actions, and the completeness of TVA's April 22, 2016, Chilled Work Environment Response Letter (Reference 2). In support of these assessments, the Conger & Elsea Team conducted a series of interviews and focus groups, with participants representing greater than ten percent of the TVA WBN employee population across all organizational levels and functional groups.   
 
Based on these assessments, the Conger & Elsea Team concluded that:
chilled work environment precursors and concerns existed in other functional areas beyond Operations,  improvement was needed to build mutual respect and demonstrate that workforce input was valued, and  gaps in effective safety communications existed.
 
Conger & Elsea recommend the following actions:
The root cause analysis conducted for the chilled work environment should be re-opened and evaluated using an additional analysis tool to assess organizational
 
and programmatic issues. TVA's April 22, 2016, Chilled Work Environment Response Letter (Reference 2) should be updated to provide the status of actions taken and the additional actions planned to address the Conger & Elsea findings and recommendations.
 
In September 2016, the NRC conducted a Problem Identification and Resolution (PI&R)
Inspection at Watts Bar. On October 26, 2016, the NRC issued an inspection report detailing the results of the September inspection. The NRC conducted a second PI&R Inspection at Watts Bar in November 2016. On March 10, 2017, the NRC issued the PI&R Inspection Report (Part 2) and Safety Conscious Work Environment (SCWE) Issue of Concern Follow Up NRC Inspection Report. Based on that the NRC documented one apparent violation because TVA was not implementing certain review processes required by a Confirmatory Order from November 2014 to August 2016. TVA is currently conducting a Root Cause investigation to determine causes and has notified the NRC of intentions to pursue Alternate Dispute Resolution. The Root Cause Investigation will identify additional corrective actions relative to the Adverse Action Process that are not currently documented in Attachment 1. The report also documented a Severity Level IV NCV of 10 CFR 50.9 (a) related to TVA's initial response to the Chilled Work Environment Letter. TVA is reviewing the NRC's position and assessing actions that may be taken in response.
