A nine-member team from Tokyo Electric Power Co. visited Savannah River National Laboratory and other SRS facilities from Feb. 29 to March 2, before traveling to Pacific Northwest National Laboratory for three days of similar discussions.
Presentations at both sites included topics such as radiation detection, fate and transport of radionuclides, treatment and reuse of contaminated water, inspection and characterization of spent fuels, stabilization and decontamination of reactor sites, in addition to characterization, remediation and control options for contaminated soils and water in surrounding regions.
The visit resulted from an invitation issued by Deputy Secretary of Energy Daniel Poneman and followed two workshops held jointly by the government of Japan and the U.S. Department of Energy, first in Tokyo and most recently in Washington state.
A Savannah River National Laboratory spokesman said the visits, disclosed in a news release, were kept secret under a mutual agreement between SRS and Pacific Northwest National Laboratory to divulge the events only after visits to both sites were concluded.
Since the March 2011 earthquake and tsunami that damaged the Japanese nuclear plant, U.S. national laboratories have collaborated to provide advice to U.S. and Japanese government officials and to support the development of potential mitigation and recovery strategies.
