Attachment 4

listed installed breakers which were confirmed untraceable or not currently proven traceable.

The current status of these items is:

1 All 10 breakers.were replaced prior to the ITE/JL3 I

BVPS-2 startup from refueling.

Heinemann/CD3-Z42 These breakers were custom-made for DLC since-they were not a normal Heinemann catalog item.

Therefore, they could only have been obtained'from the manufacturer.

All others -

Traceability has been established.

This concludes our response to this bulletin.
