Title: Investigation of Bonded Jacket Cable Insulation Failure Mechanisms: HELB Environment Results

Abstract

When overaged from thermal or radiation environments, composite insulation composed of a layer of ethylene propylene rubber (EPR) covered with a bonded layer of chlorosulfonated polyethylene (CSPE[Hypalon]) can crack if subjected to steam environments associated with loss-of-coolant accidents (LOCAs). The work described in this report evaluated the effects of a lesser accident, a high-energy line break (HELB), on the aged insulating materials. The object of the test was to determine if the same cracking concerns exist for the less severe HELB environment. The work is based on the use of aged specimens that were prepared under the test program described in EPRI report Investigation of Bonded Jacket Cable Insulation Failure Mechanisms (1001002).
