EXPRESSION OF INTEREST (EOI)- for the Refurbishment of Concrete Coated Waste Transfer Pits

Washington River Protection Solutions LLC (WRPS) located in Richland; Washington at the Hanford Clean-Up Site has a requirement to comply with the requirements of Washington Administrative Code (WAC) 173.303.640. For the waste transfer piping system which transport dangerous waste between underground storage tanks, secondary containment concrete vaults are utilized at various piping termination points. These concrete vaults which contain additional piping, valves, structural components, etc. are referred to as pits. To satisfy the regulatory requirements, WRPS installs and maintains special protective coatings with inspections performed by National Association of Corrosion Engineers (NACE) Coating Inspector Program (CIP) qualified inspectors in accordance with the WRPS procedures.

WRPS currently has multiple waste transfer concrete pits that have not been in service for multiple decades. To facilitate new projects, these pits will require extensive repair and refurbishment to reestablish secondary containment and pass a NACE inspection to demonstrate that they are fit for use. The refurbishment presents several challenges with existing pit obstructions, radiological contamination, and radiation exposure to workers. Generally, long reach and/or remote tools are used to facilitate most of the work at these structures to mitigate a number of the hazards the workers would be exposed to if a manned entry was to be performed.

WRPS is issuing this Expression of Interest (EOI) to identify prospective Subcontractors who may have the capability to provide commercial and/or special tools and relevant industry experience to inform the execution of work to repair and refurbish these pits while maximizing worker safety and timely execution.

Expression of Interest for the Grouting and Disposal of Mixed Low-Level Waste from Hanford Tanks

The Department of Energy Hanford (hereafter termed the Department or DOE) (through Washington River Protection Solutions (WRPS)), is seeking industry input on options available to implement a recommendation made by a team of subject matter experts from a Federally Funded Research and Development Center (FFRDC) on implementing alternative treatment methods for the Hanford tank’s low-activity waste (LAW). To that end, the Department seeks to better understand the capabilities of industry to provide Land Disposal Restriction (LDR) treatment, grout, and dispose of a mixed low-level waste (MLLW) separated from pretreated Hanford tank waste.

This EOI describes the process by which the Department will interact with identified interested parties and provide said parties with the information they require to assess their capabilities to meet the stated need. Based upon the information received, DOE may host an Industry Day event in the future where interested commercial parties can present their strategies for providing LDR treatment, grouting, and disposing of this MLLW. This information may also be used in the development of an acquisition strategy for the commercial treatment, grouting, and disposal of the subject waste stream.
