MONTPELIER, Vt.—A top official at the Vermont Yankee nuclear plant was permanently relieved of his duties and placed on leave, the plant owner's CEO said Tuesday, less than a week after Gov. Jim Douglas demanded management changes over misstatements made to state officials.
Entergy Nuclear chief executive J. Wayne Leonard did not identify the official by name. But he described the executive relieved of his duties in a way that could only apply to Vice President Jay Thayer.
Douglas' urging for management shake-up followed revelations that plant officials misled state regulators and lawmakers by saying last year the plant did not have the sort of underground pipes that could carry radioactive tritium.
"In May 2009, an
"He has been permanently relieved of his duties in Vermont, and placed on administrative leave pending the outcome of the full investigation," Leonard added.
Calls to Thayer's home were not immediately returned Tuesday.
On Jan. 7, it was announced that tritium, an isotope said to cause cancer if ingested in high amounts, had been found in elevated levels in a groundwater monitoring well at Vermont Yankee. Plant and federal Nuclear Regulatory Commission officials have maintained tritium has not appeared in groundwater at concentrations that pose any threat to public health or safety.
On Tuesday, plant spokesman Robert Williams said the highest reading yet of tritium had been reported in a monitoring well at the Vernon reactor. The latest reading is four times the Environmental Protection Agency's safety limit for tritium in drinking water.
Leonard, speaking Tuesday about the company's fourth-quarter 2009 results to shareholders and analysts in a conference call, gave an update on Entergy Nuclear's plan to spin off a new company to own Vermont Yankee and four other northern nuclear stations.
Leonard raised the possibility that the plan could go ahead without including Vermont Yankee if the state fails soon to approve the spinoff; he said a lack of approval in Vermont might merely move completion of the deal from this spring to later in the year.
Vermont Yankee is not profitable for Entergy under the terms under its current deal to sell power to Vermont's electric utilities, Leonard said. The company is hoping to operate the plant for 20 years past the expiration of its current license in 2012 and says it will seek higher prices from the utilities then.
