1. 1. Spent Nuclear Fuel under Repository Conditions : Update and Expansion of Database and Development of Machine Learning Models

   University essay from KTH/Kemi

   Author : Maria Abada; [2022]
   Keywords : Spent nuclear fuel; spent nuclear fuel dissolution; spent nuclear fuel corrosion; machine learning model; dissolution predictions; Utbränt kärnbränsle; upplösning av utbränt kärnbränsle; korrosion av utbränt kärnbränsle; maskininlärningsmodeller; prediktioner av upplösning;

   Abstract : Förbrukat kärnbränsle är mycket radioaktivt och behöver därför lagras i djupa geologiska förvar i tusentals år innan det säkert kan återföras till naturen. På grund av de långa lagringsperioderna görs säkerhetsanalyser av de djupa geologiska förvaren. READ MORE

3. 2. On the mechanism of H2O2 decomposition on UO2-surfaces

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Darius Pakarinen; [2018]
   Keywords : hydrogen peroxide decomposition; uranium dissolution; coumarin scavenging;

   Abstract : Deep geological repository has been investigated as a solution for long term storage of spent nuclear fuel in Sweden for more than 40 years now. The Swedish nuclear fuel and waste management company (SKB) are commissioning the deep repository and they must ensure that nuclear waste is isolated from the environment for thousands of years.

4. 3. Radiation Effects on KBS-3 Barriers: SKB’s work so far

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Ismael Safi; [2017]
   Keywords : KBS-3; Repository; Radiation; Bentonite; Montmorillonite;

   Abstract : In the Swedish concept for final disposal of spent nuclear fuel, referred to as KBS-3, a three-layered protection system is used. The system consists of a copper canister holding the spent nuclear fuel deposited 500 meters in a repository built in groundwater saturated granitic rock. READ MORE

5. 4. Slow strain rate testing of welded copper

   University essay from KTH/Materialvetenskap

   Author : Kirti Teja Pasupuleti; [2013]
   Keywords : copper canister; friction stir welding; slow strain rates; creep test; knock-mecking model;

   Abstract : In Sweden spent nuclear fuel is planned to be placed 500 m down in the bedrock. The spent nuclear fuel will be contained in copper canisters. The reason behind the selection of copper is its thermodynamic stability against corrosion in the depository. The copper will be exposed to mechanical loading and will be plastically deformed due to creep. READ MORE

6. 5. Radiation induced corrosion of copper

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Åsa Björkbacka; [2011]
   Keywords : Copper; radiation; gamma radiation; corrosion; SEM; IRAS; ICP; cuprite;

   Abstract : The Swedish concept for storage of highly radioactive spent nuclear fuel is called the KBS-3 program. The proposed procedure is that the waste will be stored in a deep repository, 500 meters down in the Swedish bedrock, for 100 000 years. The fuel will be sealed inside cast iron cylinders surrounded by copper. READ MORE
