VERNON — Federal inspectors from the Nuclear Regulatory Commission gave Entergy Nuclear good grades for its handling of the radioactive water that continues to seep into a below-grade building during the early stages of the decommissioning of the Vermont Yankee nuclear power plant.

There were no safety findings included in the quarter inspection report, which was released last Monday by the NRC.

The report states that Entergy’s handling of the slightly radioactive water, which is classified as low-level radioactive waste, was satisfactory. All other areas reviewed by the NRC inspectors, which included an inspection of the spent-fuel pool, were given approval.

“Based on the results of this inspection, no findings of safety significance were identified,” the report concluded.

“The water has slight radioactive contamination because at least some of it came into contact with surfaces inside the turbine building,” said NRC spokesman Neil Sheehan.

The problem started last year and at one point, 3,000 gallons of water a day was seeping into the turbine building during winter. The company said last month the amount was now between 700 to 900 gallons a day, and it is being shipped to Tennessee for disposal at a cost of $4 a gallon.

Entergy said the high temperatures in the turbine building when Vermont Yankee was operating apparently masked the infiltration problem by evaporating the water.

Entergy originally stored the tainted water in kiddie pools and closed tanks, but has been shipping the water to a disposal site in Idaho for the past several months.

In addition to the water infiltration problem, the two inspectors from the NRC also did a “walk through” of the spent-fuel pool area in the reactor building.

“Entergy remains committed to the safety of its employees and the surrounding community as it proceeds in the decommissioning of Vermont Yankee,” Entergy Nuclear spokesman Marty Cohn said Monday.

The report included observations by the two inspectors, interviews with Entergy employees and a review of procedures and records.

Vermont Yankee shut down in December 2014 after more than 42 years of operation. The plant is being put into long-term storage, which can last upwards of 60 years, waiting for its decommissioning trust fund to reach the $1.2 billion Entergy has estimated it needs to demolish and clean up the Vernon reactor.
