In support of NNL's CPF programme, a hydraulic press is required which can press with a force of 50 kN to produce both annular cylindrical compacts. It is anticipated that a commercial off the shelf tablet press intended for the pharmaceutical industry would be suitable for the application. The nominal dimensions of 30 mm diameter x 40 mm in height with an internal annulus of 4-12 mm. A heated die is required to allow for compacts to be produced at a temperature of up to 300ºC. Die filling should be done using automated die feed utilising a hopper system to fill the die automatically before each press cycle. The press should record data during the pressing process such as temperature, punch position, force and die wall pressure. This data will be used to optimise the pressing process and form part of the QA process.

NNL require equipment capable of producing a consistent 100 micrometer thick graphite coating onto spherical fuel kernels. The process is expected to utilise fluidised bed technology with spray powder coating. It is expected that a wetting agent and liquid polymer binder will need to be applied for the graphite powder to adhere to the surface of the kernels. Uniformity of the coating is important so consideration should be given to how this can be achieved. The equipment should be capable of drying the coated kernels once the process is complete. For more information, please email: nnl.procurement@uknnl.com and mark for the attention of Charlotte Wilson

NNL are seeking expressions for interest from Injection Moulding suppliers to manufacture Carbon Ceramic Compacts with embedded fuel kernels. The Dies are to be loaded with powder before pressing at 20MPa and 200 degrees Celsius. If this is of interest to your company, please email nnl.procurement@uknnl.com and mark for the attention of Charlotte Wilson/Emma Kirkpatrick

National Nuclear Laboratory (NNL) is currently leading a project in Phase B of the Advanced Modular Reactor design competition. As part of this project we are beginning to develop a digital twin of the thermal system of the combined nuclear reactor, nuclear power plant (electrical generation) and hydrogen production plant (hydrogen generation). The digital twin will be developed in parallel to the reactor system design. Further components, such as energy storage systems, safety systems etc will be added to the digital twin as the whole system design progresses. A digital twin represents a live coupling of the physical reality to a digital representation. In the current phase of this project the live component will be a representation of end user demand as no physical reactor demonstrator will be ready for several years. The digital twin will however help with the progress of the design, by demonstrating the required performance characteristics of key components, specifically the heat exchanger manifold that will distribute heat from the reactor to the generator or hydrogen production facility. Ultimately, we intend to use the digital twin in support of the substantiation of the business case for future phases of the AMR development programme. In order to develop this digital twin, NNL needs to understand how the heat exchanger (system) manifold could respond to the energy dynamics of the system. NNL requires consultancy support to help develop the dynamic model of the heat exchanger manifold. Responses to the attached RFI document should be sent to david.brown@uknnl.com before 17:00pm 19th January 2024. Additional information: Responses to the RFI should be sent to david.brown@uknnl.com before 17:00pm 19th January 2024.
