Radiation hardness studies and detector characterisation at the JSI TRIGA reactor

Present Services at the Triga Mark Ii Reactor of the Jsi

The 250 kW TRIGA Mark II research reactor of the Jožef Stefan Institute (JSI) has been in operation since 1966. The reactor went critical on 30 May 1966. It is a light water reactor, with solid fuel elements in which the zirconium hydride moderator is homogeneously distributed between enriched uranium. The reactor core consists of about 70 fuel elements, which are arranged in an annular lattice...

Radiation hardness of the PIBETA detector components

We have examined long term changes in signal amplitude gain, energy resolution and detection efficiency for the active components of the PIBETA detector system. Beam defining plastic scintillation counters were operated in a ∼ 1 MHz stopped π + beam for a period of 297 days, accumulating radiation doses of up to 2 · 10 6 rad. Detectors in the charged particle tracking system—a pair of cylindric...

Beam calculation for TRIGA reactor

As part of the INIE project of the Big-10 consortium, efforts are underway at UIUC to assemble and test a set of codes that can be used for the design of the next generation of research reactor. SCALE 4.4 has been selected as one of the set of codes for this purpose. We here report some results of analysis of a TRIGA reactor using KENOVI, one of the codes in the SCALE system. Results are presen...

TRIGA Mark-II Research Reactor

The present work gives a methodology for assessing radiological concentration of I, I, I, I, and I due to a hypothetical accident of TRIGA Mark-II research Reactor at AERE, Savar, Bangladesh. The concentrations were estimated through different pathways like ingestion of vegetation, milk, and meat from air and ground deposition. The maximum air concentrations for all 16 directions were found at ...
