Decontamination Pit Shields

Bechtel National Inc.

The high-level waste (HLW) Melter Cave 1 and 2 Decontamination Pit Shielded Lids primary functions are to provide shielding and contamination control between the crane decontamination areas and the equipment decontaminations pits.  Normally, these lids remain in the closed position to provide radiological shielding and to regulate airflow into the decontamination pits.  The lids hydraulically opened and closed.

This project was designed, built and tested at the Petersen Inc. facilities. It was qualified for nuclear facility use using structural, seismic, electrical & instrumentation, hydraulics, canister impact, factory acceptance test, commercial grade dedication and environmental qualifications.
