The HTMR100 Reactor is a High Temperature Gas Cooled Modular Reactor. The value of the transaction has not been disclosed, reports Southafrica.info. This capability avoids the need to periodically shut down the reactor for refuelling. Johannesburg, South Africa… Government has decided to no longer invest in the Pebble Bed Modular Reactor (PBMR) project, says Public Enterprises Minister Barbara Hogan. The Pebble Bed Modular Reactor (PBMR) being developed by the South African utility Eskom together with international partners is a 400 MWt nuclear reactor that uses the TRISO (refer to Section 1.2) fuel embedded in 6 cm diameter graphite spheres (pebbles) with a projected electricity output of 165 MWe. In some way initiated by the former PBMR project in South Africa, many studies have looked into small nuclear reactors, and they conclude that power generation reactors of 150 MW or so could be commercially viable – which no one had thought previously possible. While technologically sound, and potentially ideal for developing countries, the PBMR has been unable to secure sufficient investment to keep it going. South Africa Demonstration Plant Status Assuming regulatory approvals, the demonstration plant will begin construction in 2008 with the first fuel load scheduled for 2012. The pebble bed reactor technology allows for online refuelling of the reactor by inserting fresh fuel at the top of the core and extracting spent fuel at the bottom. The project entails the construction of a demonstration power plant at Koeberg near Cape Town and a fuel plant at Pelindaba near Pretoria. This gives the reactor its name: the pebble-bed reactor. Pelindaba, South Africa, pebble bed work site Professor Lee Langston writes in Mechanical Engineering University of Connecticut retired professor Lee Langston has just published a very clear, readable history of the pebble bed modular reactor project underway in South Africa. Locality: Subscribe to view content . The Pebble Bed Modular Reactor (PBMR), like most new reactor ideas, is a reincarnation of an old reactor idea. South Africa and China join forces in commercialisation of pebble bed technology. South African Engineering House with Cutting-edge Nuclear Pebble Bed Reactor technology. While various options were explored to commercialise its Pebble Bed Modular Reactor (PBMR) in the past, Eskom now intends to dispose of the company, providing the market with unrestricted options to pursue. The Pebble Bed Modular Reactor (PBMR) is a particular design of pebble bed reactor under development by South African company PBMR (Pty) Ltd since 1994. The proposed AHTRs are intrinsically safe, modular, efficient and modern gas-cooled reactors which are deployable in even the remotest areas of the country. The design of the reactor is based on proven technology and therefore no new basic technology development is needed. Development of this in Germany was eventually abandoned but the idea was taken up during the 1990s by the South African utility Eskom, which continued development until 2010 when it appears to have been halted. The approach to small intrinsicly safe modular units ensures continuous production. Knowledge gained from the German AVR led to the design of a 300MWe (750 MWth) thorium high-temperature reactor … South Africa started to develop its pebble-bed reactor design in the mid-1990s, hoping that it would deliver cheap electricity and open up a lucrative export industry. After 10 years of development it said it was abandoning plans to build a full-size 165-megawatt-electric demonstration plant. Province: Subscribe to view content . Pebble Bed Modular Reactor Country: South Africa. IST Nuclear is a leading provider of services and systems for South Africa's Pebble Bed Modular Reactor (PBMR) project. Phone: 012 641 1097 The PBMR is currently under licence review and final design in South Africa, which currently has a start of construction date in 2007, with a commercial operation date in 2010. The South African government has taken the tough decision to cut its losses and cancel further investment in the Pebble Bed Modular Reactor project. STL's High Temperature Modular Reactor is a gas-cooled, graphite-moderated pebble-bed reactor producing 100 MWth and 30 MWth. The latest technology in nuclear power, the Pebble Bed Modular Reactor, may soon be operational at an unexpected location. South Africa has two nuclear reactors generating 5% of its electricity at Koeberg. Pebble Bed Modular Reactor South Africa • 165 MWe Pebble Bed Plant - ESKOM • Direct Helium High Temperature Cycle • In Licensing Process • Schedule for construction start 2007 • Operation Date 2011/12 • Commercial Reference Plant. The engineering maturity of pebble bed reactors, supported by experimental facilities, makes the HTMR100 as a Generation IV reactor licensable within the next few years. This article outlines Eskom’s approach in the development of the advanced high temperature reactor (AHTR) programme, commonly known as the pebble bed modular reactor (PBMR) restart. A briefing session will be held in Pelindaba on 24 February and the deadline for submissions is … As a result the project had to dismiss 75 per cent of its staff. A surprise announcement was delivered to the pebble bed modular reactor (PMBR) project in South Africa’s 2010 budget – it would no longer obtain significant state funds. Our Mozweli Nuclear Engineering team have the knowledge and Intelectial Property to bring all the engery we require to the World in a clean, sustainable and efficient way.

This Reactor can facilitate a variety of different fuels using the same geometry. Storm over pebble bed modular reactor as Eskom ponders its resurrection. In February, Pebble Bed Modular Reactor (PBMR) Ltd., an eponymously named South African company announced a major change of strategy. In this case the old idea is the “high temperature gas reactor” or HTGR, that then was proposed in a modular version, known as the MHTGR. Pebble bed reactor scheme. Unless the South African project is revived, that leaves only China developing pebble bed concepts (with one small prototype operating and one 200 MW 'demonstration reactor' planned or in the early stages of construction). Building G, Lytteltown Office Park, 1 Shelanti Avenue, Centurion, 0046. It had spent in the region of nine billion rands of state funds without […] Westinghouse opened its newly acquired South African operation on Monday under the name Westinghouse Electric South Africa. Megan Lindow reports from Cape Town, South Africa. Reitsma, Frederik. While various options were explored to commercialise its Pebble Bed Modular Reactor (PBMR) in the past, Eskom now intends to dispose of the company, providing the market with unrestricted options to pursue. From Germany to South Africa : A German scientist, Prof. Rudolf Shulten developed the concept for a modular pebble bed reactor in Germany in the late 1950s. “Pebble Bed Modular Reactors Vesus Other Generations Technologies: Cost and Challenges for South Africa.” Proceeding of Global 2011 (2011): 1-8. The term modular stems from the Construction of a demonstration Pebble Bed Modular Reactor in South Africa has been delayed. The Pebbel Bed Modular Reactor Design and Technology Featuers .
