DESCRIPTION OF THE SSTAR CONCEPT

The Small Secure Transportable Autonomous Reactor (SSTAR, [IX-1]) is a 20 MW(e) (45 MW(th)) exportable, small, proliferation resistant, fissile self-sufficient, autonomous load following, and passively safe lead cooled fast reactor (LFR) concept for international deployment and deployment at remote sites. Potential users for the SSTAR include customers looking for energy security with small capital outlay; cities in developing countries, and […]

PROBABILITY OF UNACCEPTABLE RADIOACTIVITY RELEASE BEYOND PLANT BOUNDARY

It is expected that the probability of unacceptable radioactivity release beyond the plant boundary would be less than 1 x 10-7/year. VI-7. MEASURES PLANNED IN RESPONSE TO SEVERE ACCIDENTS One of the important design objectives of the AHWR is to eliminate the need for any intervention in the public domain beyond plant boundaries as a consequence of any postulated accident […]

DESCRIPTION OF THE STAR-LM CONCEPT

The Secure Transportable Autonomous Reactor-Liquid Metal (STAR-LM, [IX-1]) is a scaled up version of SSTAR at a power level of 181 MW(e) (400 MW(th)) for high efficiency electric power production with optional production of desalinated water using a portion of the reject heat. The STAR-LM reactor vessel size is assumed to be limited in height by a rail shipment limitation […]

SAFETY DESIGN FEATURES OF THE GT-MHR

Experimental Design Bureau of Machine Building (OKBM),Russian Federation VII — 1. DESCRIPTION OF THE GT-MHR CONCEPT An international project for the GT-MHR was launched in 1995 by the Russian Ministry for Atomic Energy and the General Atomics Company of the USA. Later, the project was joined by the Framatome[53] (France) and Fuji Electric (Japan). At present, the preliminary design is […]

SUMMARY OF PASSIVE SAFETY DESIGN FEATURES FOR SSTAR

Tables IX-5 to IX-9 below provide the designer’s response to the questionnaires developed at the IAEA technical meeting “Review of passive safety design options for SMRs” held in Vienna on 13-17 June 2005. These questionnaires were developed to summarize passive safety design options for different SMRs according to a common format, based on the provisions of IAEA Safety Standards [IX-2] […]

PASSIVE SAFETY DESIGN FEATURES OF THE GT-MHR Safety objectives

The top level safety objective is to provide protection for the personnel, public, and environment against radiation and radioactive contamination. This main objective must be fulfilled at every stage of the reactor plant lifecycle and in all operating conditions; more specifically it is defined by the radiation and technical safety objectives.
