Development of High Temperature Reactor Fuel
One of the types of nuclear reactors is the high temperature reactor (RST). This type of reactor can be made modular according to the need of the local electricity. The high temperature reactor besides producing electricity, also makes possible for utilizing the heat of the reactor for processes needing high temperature. The High Temperature Reactor fits with the geographic condition of Indonesia which consists of islands that have not yet any connections to the integrated electrical network.

The modular High Temperature Reactor, is one of the reactors with high level of security because the fuel is anti melting even though it is in accident condition and has an inherent cooling which could cool down by itself without any handling by anyone. The reactor was developed in Germany, South Africa, China and several of the countries use fuel in the form of balls. The ball formed fuel was made of coated particles measuring less than 1 cm which was mixed with a graphite matrix, and molding became a ball measuring 5cm in diameter, therefore forming a fuel element in the form of a 6cm diameter ball.

The coated particles which become the high temperature reactor fuel, consists of small particles of UO2,  with 4 layers, one buffer layer and 3 isotropic layer. The first layer is a low density pyrocarbon as a buffer, a place to store the results of fission, the high density pyrocarbon to maintain the fission results, the silica carbide which also functions as a strengthener to further maintain the results of fission which is still coming out of the high density pyrocarbon layer, and the most outer layer of the high density pyrocarbon to protect the silica carbide. The layers of pyrocarbon and silica carbide could withstand temperatures up to 3000 oC.

NUCLEAR CORNER BATAN JOGJA

By : Retno Tjatur Endang SW (Sub Section of Scientific Documentation)

Currently maybe there are still not many of the public who know or even the employees of PTAPB BATAN who know that there is an exhibition hall which is very representative with professional touch in the field of interior design. Also im accordance to its name, the facility is situated in building 16 which location is the most north western “corner” of the PTAPB complex. The facility which is built using the 2011 Budget is the Center for Dissemination of Nuclear Science and Technology (PDIN) and has been inaugurated several months ago which does not specifically present activities of the PTAPB, but represents BATAN in general.
