Pebble bed modular reactor

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 project entails the construction of a demonstration power plant at Koeberg near Cape Town (now postponed indefinitely [1]) and a fuel plant at Pelindaba near Pretoria. Get price

PBMR: the future is now

Aug 20, 2001The PBMR uses silicon carbide and pyrolitic carbon-coated particles of enriched uranium oxide encased in graphite to form a fuel sphere, or pebble, about the size of a tennis ball. Helium is used as the coolant and energy transfer medium to a closed cycle gas turbine and generator system. Get price

PBMR Postponed

Sep 11, 2009The company had previously planned to construct a 400 MWt (165 MWe) reactor using a full-scale Brayton cycle gas turbine. According to Kriek, the revised design of the PBMR could be deployed in several energy-intensive processes, including: coal gasification and liquefaction; oil extraction from tar sands; or desalination of seawater.

PBMR Project Winding Down

I've focused on the turbine problem. This is a major area of RD that has, according the PBMR Westhinghouse rep on Rod's podcast a year or so ago, noted was the biggest stumbling, and therfore, money block, to the full range, gas cooled, gas driven, PBMR-Brayton Turbine reactor set. Get price

Arguments on the Construction of PBMR Reactors in South Africa

The design was close to the PBMR because it used a gas turbine rather than a steam turbine and was planned in modules, but used fuel rods rather than pellets. This would have been developed partly to consume plutonium taken from dismantled bombs and partly as a civil reactor. The technology was developed until 1995, although it was close to Get price

Demise of the Pebble Bed Modular Reactor

In 1993, the South African utility Eskom took up a PBMR design that, unlike its predecessors, was expected to generate electricity using a gas turbine driven directly by its helium coolant. In 1999, Eskom set up PBMR Ltd. to develop and market the PBMR and to complete a feasibility study. Get price

Advanced High Temperature Reactor Project – PBMR relaunch

the 400MWth design developed by PBMR (Pty) Ltd, showed a large international market, being competitive with fossil fuelled plant at the then hydrocarbon prices (~$20/ton coal and ~$3/GJ natural gas). • The nuclear safety level for the PBMR was significantly higher than is claimed for any current nuclear power plant (in service or under Get price

Eskom considers relaunch of pebble bed modular reactor

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. 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 technology base for these reactors, [] Get price

Gas Turbine Introduction and Vibration Diagnostic Basics

Gas Turbine Introduction Styles of Gas Turbines Micro-turbines – typically produce tens to hundreds of kW. Some corporations advertise micro-turbines up to 1 MW, but that size of this style of machine is rare to date with most being in sizes less than 400 kW. Aero-derivative gas turbines – Typically range in size from one MW to tens of MW. Get price

Types of Gas Turbines

May 05, 2015Gas turbines can also be used to power ships, trucks and military tanks. In these applications, the main shaft is connected to a gear box (much like the turboprop) and the resulting power plant is called a turboshaft engine. In the late 1960's, turboshaft powered race cars competed at Get price
