NEWPORT, Mich. - Employees and management of Detroit Edison Co.'s Fermi 2 nuclear plant in Monroe County have satisfied the Nuclear Regulatory Commission with their improvement in self-diagnosing problems and resolving them.

In a letter dated March 2 and made available to the public this week, the NRC told Donald Cobb, Detroit Edison assistant vice president for nuclear generation, that government inspectors noted sufficient progress in what was described as a "cross-cutting" issue affecting training and various plant procedures.

"Based on this observed improvement, the [NRC] staff no longer has a concern with the scope of your efforts or progress in the cross-cutting area of problem identification and resolution because the range of corrective actions and observable trends indicate you have effectively addressed the cross-cutting theme associated with these findings."

"Therefore, the cross-cutting issue is now closed," according to the cover letter for the NRC's latest assessment report.
