UK Public Sector Contracts & Tenders

The project is tasked with the receipt of two flasks (the single module flask (SMF) and the neutron source container (NSC)) into an Active Handling Facility at NNL Windscale. The flasks will contain MOD reactor fuel for post irradiation examination (PIE). Unlike most fuel received into the facility this fuel must be horizontally posted into the cave system. Such imports have not been undertaken for almost a decade and a new import process is being developed. As part of the design process, fault identification has identified the need for an assessment of the possible impact of a fire on the operations being undertaken.

NNL requires a single stage of the 1 and 2 cm size contactors, to allow for the scale-up comparisons of contactor behaviour between the 1cm contactor from the Institute for Nuclear and New Energy Technology (INET), Tsinghua University, Beijing (INET design) and 4cm contactor from the University of Leeds (RR design).

Multi-Lot framework agreement to provide a compliant route to market for Fabrication and Machining Services for Nuclear and Non-Nuclear facilities.

A single supplier contract for the National Nuclear Laboratory to support the design, manufacture, testing, training and installation of a series of interconnected Gloveboxes.

NNL are seeking a single supplier to provide a Raman Microscope as detailed in the procurement specification. For further details please see the tender documents available.

National Nuclear Laboratory is seeking a single supplier to support surveying and research of the current Civil Nuclear Landscape on behalf of NIRO. This research has previously been conducted in house and an example of the previous year's output is available to view, however with the number of survey respondents increasing additional resource is required to undertake the surveying and reporting. Option to extend a further beyond its initial period to allow a second survey and report to be produced in 2 years' time subject to funding being provided and satisfactory supplier performance.

Assistant Project Manager (APM) - the individual will support the PM in delivery of the HAWTT and Automated Stores projects for Sellafield Ltd. Contract awarded under Crown Commercial Service Framework RM6165 - Lot 5 Defence.

The design, supply, and non-active commissioning of a microwave digestion system, for use on active materials containing boron carbide, to B170.

Supply, Delivery and Installation of a Hydrogen Analyser

Task 1 - Image Enhancement of Port Profiler Videos Development of a software function to enhance the image quality of existing inspection videos. The university will apply their existing image enhancement techniques (which were developed for a different application) to existing videos. They will then evaluate the results and further develop the implementation of the algorithms to make then suitable for use on the inspection videos. Task 2 - Image Processing for Corrosion Detection in SPRS Development of image processing techniques to automatically detect and quantify corrosion in inspection videos of SPRS.

Sellafield Ltd (SL) is currently in the process of emptying sludge from a series of tanks on the Sellafield site. This contract is for the procurement of ROV Crawler components for incorporation into sludge retrieval system is required to facilitate this task.

What is Included The scope of this procurement exercise is the completion of the detailed design, manufacture and testing of the ventilation line for the SMF extract.The following activities associated with design of the SMF extract vent line are included in this procurement specification:-  Project Start-up Meeting  Detailed Design  Design Review  Manufacture  Testing  Supply of design and manufacturing documentation including LTQR pack.  Design substantiation of the Vent Line, Vent Line Support Brackets, and any connections to the Vent Line to Safety Function Class 2 in accordance with SLP1.02.10. The above listed project activities are to be carried out with the involvement of NNL. Regular update meetings will be required with the NNL project team and NNL's Lead Engineer is required to accept key project documentation.The supplier scope of supply shall begin from the specified interfaces in the Cave 6 garage area and end at the connection to the red extract. The supplier shall carryout an assessment prior to commencement of design work to confirm that the discharge of these extracts from SMF operations in to the Red Extract ductwork will not adversely affect the existing Red Extract Ventilation System. The supplier shall supply NNL with the following:-  Vent line (including replacement section of red extract duct work)  Brackets and fixings  Technical and manufacturing documentation including test certificates. What is Optional The following should be included in the suppliers tender return, with a separate price, as anoption that NNL may choose to pick up:  Installation of the SMF extract vent line and the replacement section of the red extract duct work at the NNL Windscale Laboratory (also known as the Active Handling Facility).

NNL are awarding a single supplier contract for the supply of one Glow Discharge Mass Spectrometer.

The National Nuclear Laboratory are awarding a contract for Heat Treatment Furnaces.

Translation services, direct award via Lot 1 of the CCS Language Services RM6141

Non-active electrochemistry data for AGR cladding has been generated and modelling evaluation was carried out by NPL, using the newly measured data to guide inputs, to predict susceptibility of the fuel cladding to SCC in caustic conditions. Following these initial experiments, additional non-active testing has been carried out and subsequent further modelling tasks and development have been recommended. NPL will carry out the following Tasks: • Investigation of the sensitivity of the modelling results (tip acidification and tip chloride accumulation) to the transfer coefficient related to the cathodic reaction. • Investigation of the sensitivity of the modelling results (tip acidification and tip chloride accumulation) to the passive current density. • Modify previous COMSOL simulation model of crack electrochemistry for advanced gas-cooled reactor stainless steel cladding in pond storage to include the presence of boric acid. • Modify the model to account for the dependency of the crack-tip current density on the local electrode potential. • Assess numerical convergence issues related to the very sharp change in electrode kinetics between the crack walls and crack-tip and endeavour to resolve. • NPL report containing the modifications to the previous model and example of results. • Modify COMSOL model

National Nuclear Laboratory award the contract for Software support via ccs G cloud to ensure continuity of service support to key software components.

There is a demand from Sellafield Limited to improve inspection of Special Nuclear Material (SNM) packages and store infrastructure to ensure continued safe and secure storage. SL have issued two requests for quotation (RFQ) to produce feasibility studies to examine / inspect SNM packages in two arrangements, ex-situ, and in-situ. For each arrangement an optioneering exercise would be performed to identify potential inspection system solutions and a down-selection to a preferred technology option. The scope of work for this contract will only cover the arrangements for ex-situ, details of this are as follows: • Investigate options to use existing concepts of the Automated Stores Project via existing Kuka tooling, concepts for inspections buggy and temporary stores to implement a package inspection capability.

Contract award notice for support with a study in Intercalation as part of the broader AMR Lot 2 - Fuels Project. The contract value is a maximum of £150,000 and in order to meet relevant milestones the deadline for completion is 29th November 2024.
