Cintula, Reactor Systems Engineer Reactor Systems Section GE Im CE Reactor Operations Analysis Branch Division of Safety Programs Office for Analysis and Evaluation of Operational Data DELAMINATING FOIL INSULATION IN PRIMARY CONTAINMENT AEOD/T923 This study completes our investigation of the large quantities of loose aluminum o
1 found throughout the drywell during the start of a refueling outage at Sus uehanna-2 (LER 388/88-010).
The aluminum foil resulted from extensive delamination of insulation used in the drywell.
As the NRC has long been concerned with potential sources of debris generation in containment, and because the generic issue was resolved in 1986, the data bases were surveyed to see if similar problems might still be ongoing in the nuclear industry.
The data searches did not find any additional recent events so it would appear that the insulation delamination was an isolated occurrence and further industry action would not be appropriate at this time.
