TVA Nuclear’s Process for Addressing Nuclear Regulatory Commission’s 2009 Confirmatory Order

In March 2016, the Nuclear Regulatory Commission (NRC) issued a Chilled Work Environment Letter to Watts Bar Nuclear Plant as a result of an investigation that concluded that a chilled work environment existed in the Operations Department because of a perception that operators were not free to raise safety concerns using all available avenues without a fear of retaliation. In response to the Chilled Work Environment Letter, TVA assessed the actions taken in response to a Confirmatory Order (CO) issued in 2009 and determined that not all of the actions had been implemented effectively. As a result of the ineffective implementation, we initiated a review of the process TVA used to address the 2009 CO. We concluded there was a weakness in the approach that TVA followed for addressing the 2009 CO. TVA did not have a formal process or procedure directly related to how a CO issued by the NRC should be addressed. TVA’s approach did not assign accountability or provide oversight to govern the implementation and continued execution for on-going actions. A potential contributing cause was TVA’s intent to address the underlying issue only and not to prevent recurrence.
