Summary of information received via fax:
The Shaw AREVA Mixed Oxide Fuel Fabrication Facility found nonconforming
welds that resulted in cracks in
HVAC filter housings supplied to
MOX Services by Flanders. The filter housings are credited for the confinement of radioactive material. There is a possibility for additional material stresses to be placed on the subject filter housings which could cause the propagation and increase in size of the cracks. Because the cracks identified in the non-conformance report could propagate to an indeterminate size, the ability of the portions of the HDE system upstream of these filter housings to maintain the confinement boundary and perform its safety function cannot be determined.
MOX Services will ensure repairs are performed by either the vendor,
MOX Services, or a third party. These repairs will be performed in support of the construction schedule.
