Transformer Pad Remediation During Holiday Outage

On-site remediation operations are challenging in a fully active facility.  Decontamination activities have to be efficiently completed within the narrow time window allotted by temporary and infrequent outages. Remediation specialists must not only decon facilities without disturbing existing operations, or background cleanliness levels, but they must get out quickly as well, without interrupting resumed plant functioning.

At Kwajalein Atoll, in the Republic of the Marshall Islands in the South Pacific, the US Army decided to undertake a major effort to remove PCB contamination from the island. As part of that effort, PCB contaminated equipment was removed from service and placed in a warehouse until proper disposal could be arranged. But after only several months of storage, PCB fluid from the equipment had leaked and was detected on the concrete floor of the facility.

Advanced Sciences, Inc., the environmental service coordinator for the cleanup, determined that solvent cleaning would present both safety and logistics problems for the island and would be of questionable effectiveness. The job had to be completed right the first time.

Canadian Facilities Purchase VAC-PAC Systems for Decontamination and Decommissioning

When the Canadian government decided to sell government agency owned and operated nuclear facilities to private enterprises, the need arose for a major decontamination operation. Although the need was not urgent, the decision assumed a high profile as the use of these facilities would be entering a new phase for nonnuclear purposes.

Decontamination of Office Building Shows Scabbling to be Effective

Disaster struck ten years ago, when a two year old, 18-story office building in the northeastern United States experienced a fire. PCBs escaped from a transformer in the mechanical room and spread throughout the entire building.

The environmental service coordinator for the cleanup responded and decontamination began. Most of the building was decontaminated using conventional techniques. However, the mechanical room, the most contaminated area of the building, had been left alone since the accident and reserved as the last area to be cleaned.

Back in the 80’s , about 10 gallons of PCB contaminated oil escaped from a transformer. While plant management didn’t consider this to be a major problem at the time, changing regulations and more stringent remediation regulations forced a Midwest manufacturer into a potentially disruptive, unplanned cleanup. Pentek’s rapid response allowed operations to continue at this facility during the cleanup activities.
