Nuclear Regulatory Commission Chairman Gregory Jaczko said his agency will help the Tennessee Valley Authority to get Alabama's Browns Ferry Nuclear Plant operating more safely.
Jaczko made the comment during a telephone conference call with reporters on Friday after he toured the plant with Tennessee Sen. Lamar Alexander, according to the Chattanooga Times Free Press.
In May, NRC gave Browns Ferry a "red" rating, which means inspectors found "high safety significance" issues.
The rating came after a reactor-core cooling valve failed last fall and prompted NRC to begin a series of inspections.
The first two-week inspection was just completed. It found that TVA "lacked rigor" when investigating the cause of problems, or simply made repairs without determining the cause. It also found problems with the plant's in-service testing program.
