TECHNICAL WORKING GROUP ON ADVANCED TECHNOLOGIES FOR LIGHT WATER COOLED REACTORSs (TWG-LWR)
Through activities conducted within the frame of the Technical Working Group on Advanced Technologies for Light Water Reactors (the TWG-LWR), the IAEA fosters the global realization and sharing of the benefits of technology advances for LWRs by facilitating international information exchange, collaborative assessments and co-operative research. The TWG provides a global forum for exchanging information on national programmes, provides advice to the IAEA on its activities in technology development for LWRs, marshals support in the home countries for conduct of the agreed activities, and is a means for the IAEA to provide balanced and objective information to all Member States on LWR technology status and advances.
The scope of the TWG-LWR includes technology advances for improvements of current LWRs, evolution of LWR design and technology, and advanced (evolutionary and innovative) LWR designs. Activities of common interest to the TWG-HWR are conducted jointly. Also, the TWG-LWR scope cuts across complementary thematic topics which are also covered by IAEA's Division of Nuclear Installation Safety, Department of Safeguards, Division of Nuclear Fuel Cycle and Waste Technology, as well as the TWG-FPT, -NFCO, -LMNPP, -NPPCI, & -T&Q. Therefore, through the one-house approach, recommended activities are sometimes carried out in co-ordination with these groups. As appropriate, activities are co-ordinated with the OECD-NEA and the European Commission.
In May, IAEA-TECDOC-1391 "Status of Advanced LWR Designs: 2004" was published. This document presents an overview of global development trends and includes descriptions of 35 advanced LWR designs, according to a common outline.
Currently the activities within the frame of the TWG-LWR include:
-
Cooperation in the 6th International Conference on Nuclear Reactor Thermal Hydraulics, Operation and Safety (Nara, Japan, 4-8 November, 2004)
-
Planning of a collaborative assessment of Advanced Applications of Water-Cooled Reactors (jointly with the TWG-HWR)
-
Preparation of the Workshop on Nuclear Power Plant Simulators for Education (International Centre for Theoretical Physics, 8-19 November, 2004
-
Conduct of a Coordinated Research Programme on Natural Circulation Phenomena, Modelling and Reliability of Passive Safety Systems that Utilize Natural Circulation (jointly with the TWG-HWR)
-
Planning of a Coordinated Research Programme on Heat Transfer and Thermo-hydraulic Code Testing for Super-critical Water-Cooled Reactors (jointly with the TWG-HWR)
-
Documentation of the results of a Coordinated Research Programme on "Establishment of a Data Base on Thermo-physical Properties of Materials of LWRs and HWRs" - presenting new measurements contributed through the CRP as well as data assessments conducted by the participating institutes.
-
Contribution to a document on "Management Strategies to Improve Economics" - led by the Nuclear Power Engineering Section.
