US body to meet over Davis-Besse nuclear plant relicensing issue

Oct 24(Reuters) - The Atomic Safety and Licensing Board will
hear oral arguments  Nov. 5-6 on a new contention regarding
relicensing of FirstEnergy Corp's 879-megawatt
Davis-Besse nuclear plant in Ohio, the U.S. Nuclear Regulatory
Commission said in a statement.   
    The new contention alleges that cracks in the plant's shield
building should be considered "an aging-related feature" that
would preclude renewing the plant's operating license for an
additional 20 years, the agency said. 
    In October of 2011, FirstEnergy identified cracks in the
shield building while conducting work to replace the reactor
vessel head and to refuel the unit, located in Oak Harbor, 120
miles (193 km) north of Columbus, the state capital.
