The scope of the Hanford River Corridor Cleanup Project (RCCP) involves D&D of several areas of the Hanford site including: 100 Area, where materials for nuclear reactors were created at nine plutonium production reactors; 300 Area, where uranium was fabricated and laboratory facilities reside; 400 Area, where facilities, except for the Fast Flux Test Facility, will be demolished; and 600 Area, where two complex and highly radioactive burial grounds are located.

In 2006, HukariAscendent (previously Ascendent, LLC) was awarded a 7-year Blanket Master Agreement to provide engineering staff augmentation support services to Washington Closure Hanford, LLC (WCH) and their subcontractors supporting the performance of the River Corridor Cleanup Project (RCCP).  The remaining scope of this work is now captured under the Plateau Remediation Contract.
