Purpose of experiment The exercise allows students to operate the reactor on their own under the supervision of a licensed reactor operator. First the students have to achieve criticality, then they have to change the reactor power level and stabilize
Exercise No. 10: Pulse experiment
Purpose of experiment The pulse experiment is a demonstration of a reactor transient in a supercritical state, made possible by the inherently safe design of the TRIGA reactor. The aim of the experiment is to perform several pulses by rapidly
Exercise No. 9: In-core neutron flux mapping
Purpose of experiment The purpose of the experiment is familiarization with the construction and operation of compensated boron-lined ionization chambers, which are frequently used as nuclear instrumentation detectors. Basic principle of chamber compensation are explained and demonstrated practically in a
Exercise No. 8: In-core neutron flux mapping
Purpose of experiment A nuclear reactor in operation is a source of a mixed neutron and gamma field, a shut-down nuclear reactor is a source of a gamma field. The purpose of the exercise is the measurement of the gamma
Exercise No. 7: In-core neutron flux mapping
Purpose of experiment The purpose of the experiment is the measurement of relative axial neutron flux distributions in several experimental locations in the core of the JSI TRIGA reactor. This is accomplished through the use of miniature fission chambers with
Exercise No. 6: Control rod worth calibration
Purpose of experiment The void coefficient of reactivity is one of the most important coefficients of reactivity for safe reactor operation. The JSI TRIGA reactor is equipped with an electro-pneumatic system with which air can be injected into the reactor
Exercise No. 5: Control rod worth calibration
Purpose of experiment The negative reactivity induced by control rod insertion is a parameter of key importance for safe reactor operation. The relation between the control rod position and reactivity is non-linear, therefore the control rod worth calibration curves are
Exercise No. 3: Fuel temperature coefficient of reactivity
Purpose of experiment A negative fuel temperature reactivity feedback effect is of key importance in inherently safe reactor design. The purpose of the experiment is to measure the fuel temperature reactivity coefficient of the TRIGA reactor, i.e. the reactivity change
Exercise No. 2: Reactor response to step reactivity changes
Purpose of experiment The purpose of the experiment is to demonstrate the principles of reactor kinetics at low power levels and in the operating power level range by inducing step reactivity changes. The reactor power response to reactivity changes is
Exercise No. 1: Critical experiment
Purpose of experiment The critical experiment is one of the fundamental experiments in Reactor Physics. Its main purpose is to determine the critical number of fuel elements and / or control rod positions in a critical assembly. The experiment is
