U.S. nuclear regulator reviewing 2 Illinois plants

 * Reviewing back-up pumps at Braidwood, Byron plants
 * Special review to be conducted in next 45 days
 WASHINGTON, April 6 (Reuters) - The U.S. nuclear safety regulator said on Wednesday it is conducting special inspections at two Illinois nuclear plants operated by Exelon Corp (EXC.N) to review the handling of two equipment issues.
 The issues at the Braidwood and Byron plants have been resolved and did not cause an immediate threat to public health, the Nuclear Regulatory Commission said in a statement.
 In February, routine inspections by the NRC found a problem with backup pumps that would be used to remove heat from the reactors in case of an accident.
 Initially, Exelon said the pumps would work if needed.
 "However, after confirmatory calculations were completed, the company concluded that the pumps would not be operable," the NRC said.
 Back-up systems at nuclear plants have come under closer public scrutiny after those at Japan's Fukushima Daiichi facility failed after the March 11 earthquake and tsunami.
 The inspection, to be carried out in the next 45 days, will review the issues in the system and Exelon's actions, the NRC said.
 The NRC also said it would look at a separate issue concerning alarms in the plants' control rooms.
