Tritium Production for Nuclear Fusion Reactors

This video discusses the production of tritium for nuclear fusion reactors using lithium as a source.

00:00:20 This video discusses the production of tritium for nuclear fusion reactors using lithium as a source. Deuterium and tritium are the main fuels for fusion reactions, with tritium being produced through a nuclear reaction between deuterium and lithium. The video highlights the abundance of deuterium in nature and the efficiency of fusion reactions in generating electricity.

🔬 The fusion reaction requires deuterium and tritium as fuels.

🌍💡 Deuterium is abundant in nature, while tritium needs to be produced in nuclear fusion reactors using lithium.

⚛️ Tritium is generated through a nuclear reaction between deuterium and lithium, resulting in a helium atom and a neutron.

00:03:45 The video explains the process of tritium production in a fusion reactor and the use of neutron multipliers to compensate for neutron deficiency. ITER relies on extracting tritium from fission reactors.

🔑 The most commonly used reaction to produce tritium in a fusion reactor is the collision between a neutron and a nucleus of lithium six.

🔑 Neutron multipliers like beryllium or lead are used to compensate for the neutron deficiency in tritium breeding.

🔑 Iter does not produce all the tritium it needs and extracts it from fission reactors like Canadian CANDU reactors.

00:07:13 This video discusses the process of procuring tritium for nuclear fusion reactors, including different methods of production and cooling systems.

💧 Heavy water with deuterium atoms transforms into tritium through nuclear fission reactions in CANDU reactors.

🔬 To produce tritium for future use in ITER, a breeding blanket is needed to transform lithium into tritium.

🧪 There are two types of breeders, ceramic and liquid, and two types of coolants, water and helium, in tritium production.

00:10:41 The video discusses various concepts and systems that will be tested in the ITER project, including ceramic breeder with helium and water cooling with liquid metal. It highlights the importance of ITER in providing crucial knowledge for future fusion reactors.

💡 ITER will test different concepts for tritium extraction and cooling systems.

🌍 ITER offers a unique opportunity to validate test blanket systems for future fusion reactors.

🔬 ITER provides fundamental knowledge in plasma physics and engineering for future fusion reactors.

00:14:08 This video discusses the extraction and use of tritium in the nuclear fusion process. It explains how tritium is obtained from ceramic or lithium-lead, transformed into tritiated water, and stored or returned to the fusion reactor.

🔑 The process of obtaining tritium for nuclear reactions involves extracting it from ceramic or lithium-lead using helium gas.

💧 The tritium is then transformed into tritiated water, which can be stored or returned to the chamber for fusion reactions.

🔬 Lithium-6 enrichment technologies, such as COLEX, are used to enrich lithium for fusion reactors, with enrichment levels ranging from 30% to 90%.

00:17:34 This video discusses the production and testing of tritium in the context of nuclear fusion. It explains how tritium is produced in ITER, its role in the fusion process, and the testing of tritium extraction and downstream systems. The video also highlights the importance of validating neutron codes for predicting tritium breeding in future commercial reactors.

💡 ITER will test different aspects of tritium production and extraction capacity.

⚛️ Neutron models and codes for tritium breeding will be validated through ITER.

🔬 Dedicated facilities like IFMIF and DONES will be used to test materials under neutron damage conditions.

☢️ ITER has a small amount of tritium stored for safety purposes.

💡 A commercial reactor needs 400g of deuterium and 700g of tritium per day.

00:21:05 Exploring the process of acquiring tritium for fusion reactors and the goal of minimizing tritium inventory in ITER.

⚛️ Tritium, a key element in fusion reactors, will be produced and processed in the Tritium Plant in ITER.

🔬 The goal in ITER is to keep the tritium inventory as low as possible through regular regeneration of the plasma chamber.

🌏 Tungsten is being studied as a plasma-facing material in ITER due to its advantage of not depositing tritium.
