Lava Tubes at Shallow Depth

M. Di Bari, and G. Zito
University of Bari, Italy

Many theoretical studies concerning lava tubes focus on the thermal disturbances generated on the earth surface. Recently a solution was suggested, where a lava tube located at a great depth h in the soil, where the ratio between h to the major axis of the ellipse a is higher than 10. However, lava tubes more frequently are located at shallower depths.  In this work we ...

Benchmarking as Key Element of Confidence Building in Safety Assessments for Radioactive Waste Disposal

E. Weetjens
SCK-CEN (the Belgian Nuclear Research Centre), Mol, Belgium

Verification of the codes applied for assessment of the long-term repository safety is typically one of the quality assurance requirements demanded by regulatory bodies, in the disposal of radioactive waste. In this paper, an internationally organized benchmark exercise is presented, in which the comparison was carried out for a selection of key radionuclides. The examples presented in this paper ...

Comparison between COMSOL and RFSP-IST for a 2-D Benchmark Problem

G. Gomes
Atomic Energy of Canada Limited, Mississauga, Ontario, Canada

RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For validation purposes, results from RFSP-IST are often compared with those from other codes. This paper documents the ...

Investigation of Natural Convective Air Flow Field through Comb Channels

R. Umhack, M. Rainer, M. Tamerle, and G. Hillmer
Process-, Environmental- and Bio- technology, MCI - University of Applied Sciences, Innsbruck, Austria

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is used. A chart showing radiator power was produced, which includes radiator power for different temperatures and ...
