What is being bought

An integrated system that will provide cooling for the high heat flux testing for the STEP in-vessel components, as well as cooling the auxiliary systems required for operation, as part of the High Heat Flux Testing and Verification Facility. This system will include: Temperature Control Unit (226 kW cooling capacity, 150 kW heating capacity and a maximum operating temperature of 350°C) Chiller (350 kW cooling capacity) Design of the Temperature Control Unit and Chiller System, along with all necessary components for operation. Commissioning of the system. Installation of the system. This system is very similar to the operational HIVE test rig which has used this supplier for the last seven years and shares the same fundamental design concept, many similar components, the cooling system and operational principles. These specific nuances are currently only understood by ICS Cool Energy. This project is an extension of the organisation’s Induction-heating based HHF testing programme and there is a stakeholder requirement to ensure equipment is directly comparable, and compatible to the HIVE facility, including physical interfaces, control, and data acquisition (see approved TD-0012050-A: SHR-010, SHR-011, SHR-013). As a result another supplier would have to retrofit the HIVE test to match the proposed HHFTVF facility increasing the cost beyond what we have been quoted. The absence of this system poses a significant technical risk to the project, as it will result in certain key stakeholder requirements falling out of scope and lead to a diminished operational capability, such as the inability to accurately replicate the first wall environment as well as future use cases.

Procurement method rationaleThis project is an extension of the organisation’s induction heating-based HHF testing program, with a stakeholder requirement to ensure that the equipment is directly comparable and compatible with the HIVE facility which has utilised a very similar cooling system from this supplier for the last seven years. This includes physical interfaces, control systems, and data acquisition (see approved TD-0012050-A: SHR-013). Our facility needs a distinctive combination of components, most of which are commercial off-the-shelf and suitable for their intended purpose. However, addressing our specific requirements requires a deeper understanding of our needs. The proposed supplier has extensive experience with the HIVE facility, making them uniquely qualified to provide post-purchase support as an extension of their current HIVE services. Using the same supplier allows for consolidation of maintenance contracts which in turn will lead to cost savings through economies of scale, streamlined administrative processes, and improved response times, ultimately enhancing budget predictability and reducing overall operational expenses. The team responsible for operating HIVE will also manage HHFTVF. Utilizing equipment from the same manufacturer will mitigate the inherent risks associated with operating new machinery and reduce the costs associated with training staff to operate and troubleshoot a new test rig. ICS Cool Energy is the best positioned supplier to fully satisfies specific requirements for the temperature control unit, including heating power, cooling power, and operational temperature.

    "procurementMethodRationale": "This project is an extension of the organisation’s induction heating-based HHF testing program, with a stakeholder requirement to ensure that the equipment is directly comparable and compatible with the HIVE facility which has utilised a very similar cooling system from this supplier for the last seven years. This includes physical interfaces, control systems, and data acquisition (see approved TD-0012050-A: SHR-013). \nOur facility needs a distinctive combination of components, most of which are commercial off-the-shelf and suitable for their intended purpose. However, addressing our specific requirements requires a deeper understanding of our needs. The proposed supplier has extensive experience with the HIVE facility, making them uniquely qualified to provide post-purchase support as an extension of their current HIVE services. \nUsing the same supplier allows for consolidation of maintenance contracts which in turn will lead to cost savings through economies of scale, streamlined administrative processes, and improved response times, ultimately enhancing budget predictability and reducing overall operational expenses. \nThe team responsible for operating HIVE will also manage HHFTVF. Utilizing equipment from the same manufacturer will mitigate the inherent risks associated with operating new machinery and reduce the costs associated with training staff to operate and troubleshoot a new test rig. \nICS Cool Energy is the best positioned supplier to fully satisfies specific requirements for the temperature control unit, including heating power, cooling power, and operational temperature.
