Federal inspectors won’t release details of new Westinghouse nuclear problems.

The US Nuclear Regulatory Commission gave security concerns as the reason.

They said they found new safety violations at the Bluff Road nuclear fuel plant for the 2nd time in 3 months.

Westinghouse was the main nuclear reactor contractor on SC Electric & Gas’s failed generation project which cost ratepayers more than $2 billion in state-approved rate hikes.

The company is working its way thorough a New York bankruptcy court.

The State newspaper reported questions have risen about whether Westinghouse properly managed a safety system that is supposed to keep nuclear material from being stolen.

Noel Pitoniak, an NRC official in Atlanta, said their concern was about tamper seals installed on nuclear material containers to make sure no one opens them.

The seals are registered to detect use of unapproved tamper seals to cover theft of nuclear material.

“We noticed they were not controlling access to those seals properly,’’ he said.

Someone with access to tamper seals could open a container, break the registered seal, remove the nuclear contents and replace the seal. As a result, auditors would be unaware nuclear material had been stolen.

“If somebody had gotten their hands on a tamper seal improperly, they could have gone into a room, stolen the material and put another tamper seal in its place,’’ said David Lochbaum, a nuclear engineer. “It looks like the room was sealed.”

This increases the chances material could be stolen for a “dirty bomb,’’ an explosive device with both nuclear and conventional materials, Lochbaum said.

Homemade bombers can spray nuclear materials over neighborhoods.

The NRC and Westinghouse said they found no evidence any nuclear material was missing or the public was ever in danger.

The NRC wrote Mike Annacone, the Bluff Road site manager, that it wants Westinghouse to fix the problem or face more penalties.
