## Summary

The National Nuclear Laboratory Limited has awarded a contract for "Active Electrochemical Measurements" in the nuclear fuels industry category. The procurement method used was a Negotiated procedure without prior publication. The contract has a total value of 27,400 GBP and is set to start on 27th February 2024, concluding on 28th June 2024. The procurement stage was marked as "award", with the tender period closing on 19th January 2024. The contract includes services to be delivered in London, United Kingdom.

This tender by the National Nuclear Laboratory Limited presents an opportunity for businesses in the research services sector, offering a chance for growth and collaboration. Small and medium-sized enterprises (SMEs) would be well-suited to compete for this tender. The contract focuses on advanced gas-cooled reactor stainless steel cladding investigations, making it ideal for companies with expertise in this area. Businesses interested in crack electrochemistry modelling and simulation tasks can leverage this tender to showcase their capabilities and potentially expand their market presence.

## Notice

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
