The Nuclear Regulatory Commission has started a special inspection at the Palo Verde Nuclear Generating Station west of Phoenix after an emergency diesel generator failed during testing last month.

The inspection began Monday and will last about a week.

"The purpose of this special inspection is to better understand the cause of the failure and to review the adequacy of corrective actions proposed by the licensee," NRC Region IV Administrator Kriss Kennedy said.

Emergency diesel generators are used to supply power to safety-related systems in case there's a loss of off-site power.

NRC requires that each of Palo Verde's three reactors have two emergency diesel generators that must be tested monthly to ensure operability.

During a scheduled test last Dec. 15, a piston failed on one of the emergency diesel generators at Unit 3.

The plant declared an alert, the second lowest of four levels of nuclear emergency.
