Abstract:

Density data obtained by a mercury pycnometry technique provided conclusive evidence that the UO2 fuel in the MH-1A Reactor densified during operation. On the basis of optical metallographic observations, the densification occurred by annihilation of small as-fabrication porosity. The fuel densification did not result in any obvious decrease in the integrity of the fuel rods or the fuel assembly.
