Kartini Reactor Experimental Facilities

Kartini reactor has several experimental facilities that can be utilized, among others: Lazy Suzan/Rotate Rack, Pneumatic Transfer System, Thermal Column and Beam Port.

Lazy Suzan/Rotate Rack

A facility located around the reactor core, a rack where samples will be irradiated. This facility consists of 40 holes where irradiation can be played and used together. Each rack hole has a diameter of 31.75 mm and a depth of 27.4 cm. Incharge and discharge of the sample is carried out through an adjustable steering tube from the top of the reactor.

Pneumatic Transfer System

This facility is a pipeline system with a length of 40 m which is connected from the laboratory to the reactor core. This system works to irradiate the sample quickly and needs to be chopped and analyzed. The sample is placed in a container with a diameter of ± 2.5 cm and is transferred from the chamber to the reactor core for irradiation and can be transferred back to the laboratory for analysis.

Thermal Column

The thermal column contains graphite measuring 1.20 m x 1.20 m, 1.60 m long, extending from the outer side of the reflector to the inside surface of the closed door. The closing door contains barite concrete and can be driven by a motor running on the tracks. It is an experimental facility utilizing gamma radiation and thermal, epithermal neutron source.

Beam Port

The neutron beam port is a facility in the form of a duct which serves to channel the neutron and gamma of the fission reaction from the reactor core to the outer side of the reactor for experimental purposes and as an irradiation facility of materials of relatively large size up to 15.2 cm in diameter. There are 4 pieces of neutron beam tube with an internal diameter of 19.5 cm, mounted through the concrete shield and reactor tank up to the reflector surface.

Some experiments on utilizing the output neutron flux from the Kartini Reactor beam port include:

  • Neutron Radiography
  • Sub critical Assembly Reactor
  • BNCT (Boron Neutron Capture Theraphy)
  • PGNAA (Prompt Gamma Neutron Activation Analisys)
