Homeland Security Capital Corporation’s Environmental Remediation Division Awarded Substantive Portion of $33.5 Million NASA-Plum Brook Reactor Contra

Homeland Security Capital Corporation (HSCC) (OTCBB: HOMS), an international provider of specialized technology-based radiological, nuclear, environmental, disaster relief, and security solutions to government and commercial customers, announced that its subsidiary, Safety and Ecology Corporation (SEC), was awarded a substantive portion of a $33.5 million NASA-Plum Brook reactor facility contract. SEC is the significant prime team member of the decontamination and decommissioning project that was awarded to Clauss Construction of Lakeside, CA.

The contract includes performing final decontamination, and radiation protection activities to support the complete decontamination and release of the facility. Also included is the safe packaging, shipment and disposal of on-site low-level radioactive waste and contaminated soil existing at the time of contract award and generated during the contract performance period.

As a prime team member, Safety and Ecology Corporation will perform the final decontamination and preparation of the reactor building, underground radioactive waste storage tanks and numerous other support buildings and structures. Additionally, SEC will manage the survey and segregation of contaminated soil, overseeing the characterization, packaging, transportation, and disposal of this material.

This cost-plus-fixed-fee contract is valued at more than $33.5 million with a thirty-month performance period. NASA’s Glenn Research Center of Cleveland, OH, manages the reactor facility.

“This is a high profile contract for our industry and provides a unique opportunity and visibility with this important client,” said Safety and Ecology Corporation CEO and HSCC President Christopher P. Leichtweis. “The Clauss team worked very hard to win this contract and received high marks for our technical approach and innovative decommissioning methods and we look forward to successfully meeting, if not exceeding, NASA’s expectations for the project.”

Former Maryland Congressman and HSCC Chairman and CEO C. Thomas McMillen said, “We are very proud of our team’s effort in gaining this contract. This project can help us make an indelible footprint in the nuclear decontamination and nuclear reactor decommissioning space for the company.”
