PBMR (Pty) Ltd
Since its establishment in 1999, Pebble Bed Modular Reactor (Pty) Ltd grew into one of the largest nuclear reactor design teams in the world. In addition to the core team of some nine hundred people at the PBMR head-office in Centurion near Pretoria, more than a thousand people at universities, private companies and research institutes were involved with the project.
In 2009 PBMR (Pty) announced that it was looking at employing the technology for process heat applications, and some pebble bed reactor contracts had been put on hold to prevent unnecessary spending
In early 2010 the South Africa government announced it had stopped funding the development of the pebble bed modular reactor, and PBMR (Pty) stated it was considering 75% cuts in staff. The decision was taken because no customer or investor for PBMR was found. Unresolved technical items, a substantial increase of costs and a 2008 report from Forschungszentrum Jülich about major problems in operation of the German pebble bed reactor AVR had discouraged potential investors. International banks refused to support the PBMR project by loans. PBMRs CEO resigned on March, 8th 2010. In future, the South African nuclear program will concentrate on conventional light water reactors.
On 25 May 2010 the company announced to staff that it intends to implement a "Care and Maintenance" Strategy. This involves the reduction of staff to 9. The stated purpose of the proposed structure is; preserve PBMR as a legal entity, preserve and optimize IP, preserve HTR license, preserve assets and solicit new investors. The strategy assumes that keeping on 9 employees in the medium term will leave sufficient funding to take PBMR to March 2013. The remaining employees will serve to end of October 2010. Some funding is foreseen for dismantling of the PBMR fuel fabrication laboratories in 2011.
In 2006, the US Department of Energy awarded the PBMR consortium the primary contract for the first phase of its New Generation Nuclear Plant (NGNP) project. The scope for the first phase of this contract, which has now been completed, was for the pre-conceptual engineering of a nuclear co-generation plant for the production of electricity and hydrogen. Requests for proposals for the second phase of the NGNP project will soon be issued, to which the PBMR consortium will be responding within the next few months of 2009. In May 2010 Westinghouse withdrew from the PBMR consortium, which led to an end of the South African engagement in NGNP. The NGNP project will continue on HTGRs with prismatic fuel elements, not with pebbles as in PBMR, as was announced in February, 2012.
