  TRIGA - Wikipedia, the free encyclopedia
TRIGA is a class of small nuclear reactor designed and manufactured by General Atomics of the USA.
The TRIGA reactor uses uranium-zirconium-hydride (UZrH) fuel and has a design which incorporates a prompt negative temperature coefficient, meaning that as the temperature of the core increases, the efficiency of the reactor decreases - so it is physically impossible for a meltdown to occur.
The prototype for the TRIGA nuclear reactor (TRIGA Mark I) was commissioned on 3 May 1958 in San Diego and operated until shut down in 1997.

Sonam Tsewang (or Tsering), Triga (or Trinkar) and Wangdu, who are all non-political prisoners, have each been given sentence extensions of at least three years after they reportedly protested about the way the UN visit was "stage managed" by the authorities, according to sources in Tibet.
According to unconfirmed reports, Sonam Tsewang is from the Meldrogongkar area near Lhasa, Triga is from Sog county in Nagchu prefecture, and Wangdu is from Shigatse, all in the Tibet Autonomous Region.
Triga, Wangdu and Sonam Tsewang, who is said to be a convicted rapist, are detained in unit two of Drapchi prison, which is occupied solely by criminal prisoners.

 Wild Triga
Wild Triga is unique in that it is a perennial grain crop, unlike all of our other grains which are annuals.
Wild Triga is generally recognized as safe as a grain relative of wheat.
Individuals with wheat or gluten allergies should use caution with Wild Triga grain as it is a close relative of wheat.

 TRIGA - 45 Years of Success
However TRIGA is no ordinary light water reactor because much of its "moderation" of neutrons is due to the hydrogen that is mixed in with the fuel itself.
Known as the TRIGA Mark I reactor, it was originally licensed to operate at a power level of 10 kilowatts, but was soon upgraded to 250 kilowatts.
This original TRIGA, designated as a nuclear historic landmark because it pioneered the use of unique, inherently safe capabilities in nuclear reactors, operated successfully until 1997, when it was permanently shut down because of its age.

The TRIGA reactor’s inherent safety is due to a physical property of its fuel elements which gives the TRIGA core a large prompt negative temperature coefficient.
At the TRIGA Mainz, the reactor core is placed inside an aluminum tank of 2.00 m in diameter and 6.25 m in height, filled with distilled water.
This decision was mainly made in connection with the research work performed and planned at the TRIGA Mainz and the training of students in the fields of nuclear chemistry, nuclear physics and radiation protection.

In fact, although the kinetic parameters of TRIGA and of fast neutron spectrum are very different, the kinetic response to perturbations are identical, except for a shifting to the lower frequencies of the reactor transfer function.
Moreover, an important feature of the TRIGA layout is the possibility to carry out, before the coupling with the accelerator, a propaedeutic experimental campaign by inserting into the current central thimble a known standard fixed neutron source, and performing static and dynamic measurements for different sub-criticality levels.
Even if the TRIGA experiments are made in a thermal neutron system, the frequency behaviour of the system transfer function is similar to its behaviour in a fast system.

 TRTR '97 Session V Proceedings
The intent of this presentation is, after a short reminder about TRIGA fuel design and fabrication to describe the new facility, with special emphasis on the safety features associated with the modification of existing fabrication buildings.
TRIGA fuel fabrication requires special skills and know-how gained by GENERAL ATOMICS along the years, and which were part of the technology transfer, and special training of CERCA technicians before the closure of San Diego workshop and during the start-up of the fabrication at the CERCA workshop.
The new TRIGA workshop at CERCA has been installed in the same building as the MTR fuel workshop, in a section which was previously used by other fabrications no longer supported in Romans.

 Small Research Reactor Workshop Sessions 1 & 2 Speakers and Abstracts
Most of the steady-state experiments were simulated; effective multiplication factors, control rod worths, excess reactivity and shutdown margin as well as the neutron flux and power distributions were used in the validation process of the physical model.
Fuel surface heat flux, heat transfer coefficients, and axial distribution of temperatures of the fuel centerline, fuel surface and the cladding `surface in the hot channel were calculated for the reactor operating at full power level.
Loss-of-flow accident analysis conducted on the forcedflowcooled TRIGA core shows that the flow reverses direction to the natural convection mode very quickly and smoothly, with essentially no interruption in the fuel temperature decay rate.

CHINESE authorities have slapped an increase in the prison sentences of three Tibetans who participated in political protests during and after the visit of a United Nations delegation to Drapchi prison in Lhasa last October, London-based Tibet Information Network reported on 7 October.
They are all said to have organised the protest because they felt the prison authorities intended to mislead independent experts from the Working Group during their visit to Drapchi prison on 11 October last year.
The three prisoners, Sonam Tsewang, Triga and Wangdu, reportedly met before the visit of the Working Group to discuss how they should make their protest.

 Criticality Safety Assessment of a TRIGA Reactor Spent Fuel Pool under Accident Conditions   (Site not responding. Last check: 2007-09-05)
If the same pool would be used for emergency core unloading, all the calculations were done with the most reactive, fresh 12 wt% standard TRIGA fuel to cover the possibility for such unloading to occur in the very beginning of the core life.
The most compact, the hexagonal arrangement, is not the most critical, neither is the contact pitch square arrangement but, depending on the number of absorber rods, the optimum moderation and, consequently the highest supercriticality is achieved for pitches between 4cm and 4.5cm.
Both, the fuel elements and the absorber rods were exactly modeled, as well as the walls of the pool, so that both, axial and radial leakage was correctly described.

 Cornell News: Ward Center and reactor to close
Robert Richardson, Cornell vice provost for research, said the decision to decommission the reactor was being made now because relicensing of the reactor by the Nuclear Regulatory Commission is scheduled for 2002-03, and thus the university was forced to make a decision about continuing operations.
The TRIGA (an acronym for teaching, research, isotope, General Atomics) reactor is the only remaining research reactor in New York state and one of 26 operating university research reactors in the United States.
During the entire 1999-2000 school year, the TRIGA reactor was used for research by Cornell faculty members for only 226 hours, representing "a serious underutilization of this facility," said Richardson.

Two irradiation tests in the C2 device from the TRIGA 14MW reactor were performed between the years 1985-1987.
Because of the axial flux asymmetry inside the TRIGA reactor core, the experimental elements are shorter in length than the CANDU fuel design.
The irradiation tests consisted in evaluation of the time-evolution of the internal pressure from two experimental fuel elements having the main design characteristics as the Romanian CANDU type fuel element design and to follow the dependence of the internal pressure of the fission gas on the fuel density.
