NRC Issues Confirmatory Order to Arizona Public Service Company
The Nuclear Regulatory Commission has issued to Arizona Public Service Co. a Confirmatory Order, documenting mutually agreed upon actions to implement programs designed to address regulatory compliance issues that contributed to two apparent violations of NRC requirements. APS operates the Palo Verde Nuclear Generating Station in Tonopah, Ariz.

The apparent violations involved the company’s failure to (1) perform a written evaluation for a change to a dry cask storage system used for spent nuclear fuel and obtain a license amendment for the way they performed accident calculations and (2) adequately analyze the consequences of a hypothetical accident involving a cask tip over on the independent spent fuel storage installation pad. The apparent violations of NRC requirements are described in a July 6 NRC inspection report.

Company officials requested the Alternative Dispute Resolution process with the NRC to discuss corrective actions. The process uses a neutral mediator with no decision-making authority to assist the NRC and its licensees in reaching an agreement.

Following a Sept. 16 meeting with company officials, the NRC issued the Confirmatory Order documenting actions that the company has agreed to take.
