UniTech Partners with PSE&G for Zion Airlock Decontamination

Recently, UniTech successfully decontaminated an airlock for Public Service Electric and Gas (PSE&G). The airlock came from Illinois’ Zion Nuclear Power Station, which is in the fourth year of a 10-year dismantling process. Now, PSE&G will use this airlock, which allows passage between environments with different air pressures or gases, for training in its Salem Station, New Jersey facility.

To prepare the airlock for its new purpose, UniTech grit blasted and used an environmentally friendly biodegradable paint stripper to remove multiple layers of coatings. This allowed for direct surface radiological monitoring for both loose and fixed contamination. In addition to performing the loose contamination surveys, technicians took direct measurements on over 1,100 unique locations on the airlock using a proprietary survey protocol developed by UniTech Corporate Health Physics.

After successfully decontaminating and surveying the airlock, UniTech has transported it to Salem Station, where it will serve as a useful tool in training employees.
