HARTFORD, Conn (AP) – The Nuclear Regulatory Commission says operators at the Millstone nuclear plant in Connecticut failed on numerous levels while testing turbine control valves last February that resulted in a power surge.

Regulators said Monday they will impose more oversight at the Millstone Power Station in Waterford.

The NRC said an operator noticed an increase in pressure and incorrectly pressed an “increase” button instead of a “decrease” button. When the pressure did not decline the operator pressed the “increase” button three more times and then pressed the “decrease” button twice.

Regulators say those actions resulted in a rapid, unintended rise in reactor power. The federal agency says a senior operator added to the problem by failing to notice reactor power was rising and withdrew control rods.

A spokesman for Millstone said plant officials have disciplined six workers and have corrected the problems.
