Nuclear Talk 2011: An Evening with Prof Dr Michihiro Furusaka

AN EYE-OPENER FROM NIPPON!

On 8^th December 2011, a Nuclear Talk organised by MEHB513: Introduction of Nuclear Technology’s Coordinator, Assoc Prof Dr Nasri Abd Hamid in collaboration with Mechanical Department, College of Engineering UNITEN has been held successfully on 8^th of December 2011. The talk intended to broaden local students view on the current nuclear technology as has been developed by other country.

The Talk has been delivered by Prof Dr Michihiro Furusaka, from the Graduate School of Engineering, University of Hokkaido, Japan. His main interests of research are neutron science, instrumentation/neutron radiation source and the device. Currently, he does actively involve in new mini-focusing small angle neutron scattering instrument.

His major involvement in various researches, by naming some examples; development and applications of neutron optical devices, neutron scattering instruments and electrical optical devices based on piezoelectric single crystals have been an eye-opener for the students.

“Neutron scattering??”

From Wikipedia, Neutron scattering is the scattering of the free neutrons by matter which require physical process and experimental technique for the investigation of materials in which very important in nuclear engineering.

Nuclear scattering devices usually come with very large sizes. Prof Furusaka himself has invented smaller neutron scattering device. This device employs focusing mirror analogous to normal magnifier to focus the neutron beams. Instead reducing spaces and allows wide neutron scattering experimentation, the result obtained from the test also more precise with high definition images produced.

One simple advantage by implementing small-scaled neutron scattering device; it minimise the sensor area to perceive the neutron scattering. The small-scaled neutron scattered device as has been developed by Prof Dr Furusaka is mfSans instrument. By using a neutron focusing technique, like the ellipsoid mirror that has been developed, a very compact SANS instrument has been made. In fact, many other devices have to be developed, such as high intensity monochromator, beam  branching device and detector with high resolution and high efficiency of count rate capabilities.

A very precious one hour of knowledge sharing with Prof Dr Michihiro Furusaka! It was very informative presentation, covering wide range of topics; the neutron scattering, short life nuclei and their implementation in cancer screening and the application of neutron matters in Apoptosis. Special thanks goes to Prof Dr Michihiro Furusaka for spending his evening with UNITEN students for presenting his remarkable works. Not forgotten, our lecturer; Dr Azlan Mostafa for his knowledge and experiences sharing during MEHB:513 lectures, thank you sir! 

Hopefully, more informative nuclear engineering related talks can be organised in our beloved UNITEN.

-Furusaka Sensei-

Obligatory poll.

Ahoy there visitors!

We've set up a poll on the right side of this page. Hope you guys could spend a little time to vote. We would like to see your take on Nuclear energy.

There'll be more polls coming up soon!

Thank you in advance.

Fast Breeder Reactors

Under appropriate operating conditions, the neutrons given off by fission reactions can "breed" more fuel from otherwise non-fissionable isotopes. The most common breeding reaction is that of plutonium-239 from non-fissionable uranium-238. The term "fast breeder" refers to the types of configurations which can actually produce more fissionable fuel than they use, such as the LMFBR. This scenario is possible because the non-fissionable uranium-238 is 140 times more abundant than the fissionable U-235 and can be efficiently converted into Pu-239 by the neutrons from a fission chain reaction.
France has made the largest implementation of breeder reactors with its large Super-Phenix reactor and an intermediate scale reactor (BN-600) on the Caspian Sea for electric power and desalinization.
