II.1.4) Short description

UKAEA are looking for partner organisations to deliver the ADS for the H3AT project as an in-kind contribution. UKAEA wishes to engage with potential prime contractors, SMEs, system designers and manufacturers of equipment for the Atmosphere Detritiation System (ADS) within the Tritium Plant located in the new H3AT Facility in Culham site, to process tritium-bearing gases and liquid mixtures. The ADS equipment package would be located on and split between all four floors of the H3AT building. Below is a list of the key components in the ADS Equipment Package.

• Inlet high-efficiency particulate air (HEPA) filter

• Low temperature recombiner (LTR) and high temperature recombiner (HTR) inlet heaters

• LTR and HTR Recombiners

• Chiller

• Blowers

• Scrubber Columns

• Buffer tanks

• Demineralized water tank

• Valves and pumps

• Process stream and tank monitoring equipment including flow, temperatures, pressures, fluid levels and pH

• Incorporation of components in skid

II.2.4) Description of the procurement

UKAEA are looking for partner organisations to deliver the ADS for the H3AT project as an in-kind contribution. UKAEA wishes to engage with potential prime contractors, SMEs, system designers and manufacturers of equipment for the Atmosphere Detritiation System (ADS) within the Tritium Plant located in the new H3AT Facility in Culham site, to process tritium-bearing gases and liquid mixtures. The ADS equipment package would be located on and split between all four floors of the H3AT building. Below is a list of the key components in the ADS Equipment Package.

• Inlet high-efficiency particulate air (HEPA) filter

• Low temperature recombiner (LTR) and high temperature recombiner (HTR) inlet heaters

• LTR and HTR Recombiners

• Chiller

• Blowers

• Scrubber Columns

• Buffer tanks

• Demineralized water tank

• Valves and pumps

• Process stream and tank monitoring equipment including flow, temperatures, pressures, fluid levels and pH

• Incorporation of components in skid

ADS (pipework, equipment, and instrumentation) shall comply with the UKAEA tritium and quality standards. The leak rate for tanks and pipework for gas shall be 10-9 mbar.L/s or better. (Figures provided are to assist in interpreting information provided, and not intended to constitute a specification or design). The purpose of the ADS is to remove and recover tritium, in all foreseen chemical forms, from gaseous effluents arising in other sub-systems prior to discharge to the atmosphere via the stack. In this way, the sub-system contributes to the reduction of tritium release via the stack to as low as reasonably practicable (ALARP).

Gaseous effluent enters the ADS system via a manifold. Downstream of the manifold, constant flow of compressed air is added to the gas stream before passing through low and high temperature recombiners. The purpose of the recombiners is to convert free and chemically bonded hydrogen isotopes to water vapour.
