Jaczko says his actions are consistent with commission policy, and he has never expressed any personal views on the Yucca Mountain project.
In an AP interview, Jaczko declined to answer detailed questions but said all his actions were aimed at nuclear safety. The inspector general's report issued Friday found he had not broken the law.
Reid, his former boss, said in a statement that House Republicans should move on and help find "real solutions for safely managing nuclear waste." ''Yucca Mountain is dead," he added.
But that report did not examine another decision Jaczko made related to Yucca: a decision to delay a vote on whether the Energy Department could withdraw its application for the project. Nearly a year after a separate nuclear licensing board ruled the application couldn't be withdrawn, the commission has yet to weigh in, even though a majority of commissioners have submitted their positions in writing.
Jaczko rejected the notion that politics is involved in the year-long delay. "Is the decision-making process taking a long time?" Jaczko said in the interview. "Yes. Is that unusual? Not entirely."
These two decisions have caused longtime staff members to become suspicious of Jaczko's motives. Before Jaczko shut down their efforts, agency experts were on track to deliver two of the safety reviews ahead of schedule. But in a memo issued June 11, 2010, Jaczko told the staff not to issue them early, a move that had employees asking if he had crossed a line. Four months later he shut down the work altogether.
Four of the most senior experts working on Yucca objected to Jaczko's move, saying it was a policy matter the full five-member commission needed to consider. Two commissioners agreed, but when one of them filed a motion to reverse Jaczko's decision, two other commissioners declined to participate. The two commissioners who declined to participate later told the inspector general that Jaczko did not fully disclose that his plans would terminate the work.
When commissioner William Magwood, a Democrat, confronted Jaczko about misleading him, the inspector general reported that Jaczko's reply was: "You should have asked."
Senior scientists with the high-level waste division also objected to a memo drafted by Christine Haney, a top NRC manager, on Feb. 4 providing the commission with an update on their work to close down the review. The memo, they argued, failed to mention that Jaczko was behind the decision to shut down the scientific evaluation.
"Every time I tried to find a different way to say chairman directed or the commission directed, I was told I could not say that," said Janet Kotra, a senior project manager who has been with the NRC for 27 years and worked full time on Yucca Mountain since 1993. "I could not include a declarative sentence that the chairman directed staff to terminate the review." She called it "a most unorthodox process."
Kotra's boss, King Stablein, supported her objection in correspondence to Haney and attached to the final memo. "Staff has struggled on a daily basis to figure out how to cope with this bizarre situation in a manner which would enable staff to maintain its integrity," he wrote on Feb. 3, 2011.
Haney, through a spokesman, declined to comment on the matter, and referred to her written response to staffers. It said that the chairman's decision fell outside the purpose of the memo and that the closure was "well vetted" by the commission.
Senior NRC officials played down the dispute over the memo in an interview with the AP, saying Jaczko has never shied away from his role in terminating the licensing review. The officials also said the objections of the staff were shared with the full commission.
Other staffers put their opinions in even stronger terms.
