LIQUID METAL FAST REACTOR TRANSIENT DESIGN... 

An examination has been made of how the currently available computing capabilities could be used to reduce Liquid Metal Fast Reactor design, manufacturing, and construction cost. While the examination focused on computer analyses some other promising means to reduce costs were also examined. 

The first information on civilian design of liquid-metal fast reactor on barge was introduced to the authors of this paper in 1996 during the week of ICENES-96 Conference here in Obninsk. 

The information on the KLT-40C reactors in its possible deployment in Pevek or near St. Petersburg has been widely publicized. On the other hand since the liquid metal fast reactor type has not proceeded into the market, it remains to the BATAN the least informed. It is anticipated that recent progress will be presented in the forum. 

In conclusion, although the CEA has now decided to focus its R D on gas cooled reactor concepts, with the prospect of perfecting a gas cooled fast reactor in the long term (4th generation), it nevertheless shall preserve activities and expertise it has acquired on sodium cooled fast reactors over the years. CEA would like to pursue further exchanges with other countries who are also engaged in liquid metal fast reactor research.

GENERAL REVIEW OF THE DECOMMISSIONING OF LIQUID METAL FAST REACTORS (LMFRs) IN FRANCE... 

This paper gives a general review of the decommissioning of Liquid Metal Fast Reactors (LMFRs) held since the last decades in France. It summarizes the main steps to process the decommissioning of RAPSODIE and SUPERPHENIX. This ejq)erimental feedback can highlight several recommendations and a general approach for the decommissioning of future LMFRs still in operation. 

SUPERPHENIX is a pool type liquid metal fast reactor. The coolant is sodium. It is composed of a main reactor vessel of 21 m diameter and 19.5 m high filled with 3250 tons of liquid sodium (Fig. 7).

In the frame of Liquid Metal Fast reactors knowledge preservation French project, CEA has separated the field of this subject in several items and has designed several experts to treat specific areas. Thus, this paper presents how this study was made dealing with the following item sodium coolant and cover gas. This paper explains what were the main difficulties by making this study and how they can be solved. 

Development of R D linked to Liquid Metal Fast Reactors had an important stop in France since the decision of the final shutdown of Superphenix in 1998. From the very beginning of this technology until now with the decommissioning aspects, France have accumulated a huge knowledge in this field mainly shared by three companies CEA, EDF and FRAMATOME ANP.

The BN-350 nuclear power plant has been used for seawater desalination and electricity production for 23 years, the longest of any commercial liquid metal fast reactor (LMFR). During that time much has been learned about successful LMFR operation and design. The present paper describes some important design features of the BN-350 NPP and presents some performance results from the whole operational period. 

Under the sponsorship of the Central Research Institute of Electric Power Industry (CRIEPI), Toshiba Corporation has designed the 4S-50 Liquid Metal Fast Reactor, which supplies electricity to a desalination plant, supported by the Technical Advisory Committee of4S.

There is one significant difference. Depending upon design, a positive void coefficient is possible with a molten salt coolant. Several other reactor types have this characteristic liquid-metal fast reactors and heavy water reactors. A positive void coefficient implies that if the core looses all coolant, the power level increases.

Fluctuations in the lower part of the hot pool. In a Liquid Metal Fast Reactor, the bottom part of the hot pool is a transition area between the hot and cold zones of the reactor. It is called the "corps mort" area. This region is armular and bounded laterally by the core barrel and the outer shell called which is called the redan. Its behaviour is linked to two conflicting phenomena ...
