【Summary】

This conference was broadly divided into two parallel tracks: on supercomputing in nuclear applications and on Monte Carlo simulation. There were up to 7 sessions of talks in each track. The conference attracted 377 participants (221 from within Japan, and 156 international attendees) and confirmed the importance of computational studies to the fields of nuclear energy and radiation research.

In the Supercomputing in Nuclear Applications (SNA) track, latest results were presented on reactor physics, thermal hydraulics, nuclear fuels, reactor structural materials, resulting in significant exchanges of information and discussions. Reflecting the developments of massively parallel supercomputers over recent years, simulations are now possible with greater temporal and spatial resolution than before, and this was the subject of a number of talks. The development of multi-scale multi-physics simulation techniques has become a major trend for tackling the complex, composite, problems in atomic energy.

In the Monte Carlo (MC) track, latest research results were announced on advances of Monte Carlo simulation theory, code developments, and practical use of Monte Carlo simulation. The Monte Carlo simulation theory talks covered the problems of eigenvalue calculation convergence, bias and under sampling. It is increasingly possible to evaluate statistical uncertainties with high precision. In addition, the deterministic / Monte Carlo hybrid simulation technique is showing promise for reducing uncertainties in shielding calculations. Code development talks covered improvements to physics models, verification studies, and calculation precision improvements. Stand-out applications of the Monte Carlo technique were for reactor and shielding calculation problems (including technologies for model development), and combined neutron transport – material damage simulations. In the medical applications and radiotherapy field, it is expected that a new field will develop for nanodosimetry research.

【Program Outline】

　

October 17 (Sun)	Tutorial on the FLUKA Monte Carlo Simulation package developed at CERN. Registered participants received copies of the FLUKA code and a practical tutorial on its use.
October 18 (Mon)	Atsuyuki Suzuki, President of JAEA, gave the welcome address and Motoshi Shinozaki who heads MEXT’s Nuclear Power Research Division gave the congratulatory remarks. Shunsuke Kondo, Chairman of the Japan Atomic Energy Commission, proceeded to give the keynote speech titled ‘Nuclear Research and Development Strategy in Japan’. This was followed by three invited talks covering movements in supercomputing use in Japan, America and Europe. The main part of the day included 64 talks and 21 poster presentations.
October 19 (Tue)	Three invited talks covered cutting-edge supercomputing research in the nuclear sciences field. These were followed by 65 talks and 29 poster presentations.
October 20 (Wed)	On this day there were two invited talks on Monte Carlo simulation, and 93 talks and 25 posters.
October 21 (Thu)	After 37 oral presentations, the awards were given for the student papers. The main conference concluded with the closing talk and the announcement of the next SNA+MC conference by its hosts. 70 attendees then stayed to participate in a tutorial on the Particle and Heavy Ion Transport System (PHITS). The tutorial consisted of practical examples of calculations using PHITS. Participants from both Japan and abroad stayed for this tutorial, indicating the high level of interest in the PHITS code.
October 22 (Fri)	The day of the conference technical tour included visits to the advanced HIMAC and high-intensity proton accelerator J-PARC facilities.
