Summary of HRT Run 25

Description: Run 25 was the final period of power operational of the HRT. The reactor was operated for periods of 62, 8, 52, and 80 hours at 5 Mw with no outward indication of fuel and core and blanket average temperatures of 270 and 230 deg C, respectively. The uranium concentration in the was 1.7 to 2.0 g U/kg D/sub 2/O. Longer periods of operation were prevented by mechanical difficulties, notably with the fuel feed pump. While the reactor was subcritical after the last of the above runs, the upper patch… more

Lessons from design and manufacture of US LCT coils

Description: In the international Large Coil Task (LCT), US industrial teams have finished one coil and are nearing completion of two others. Of the lessons learned, the ones that apply most widely to advanced technology development have to do with the difficulty of scheduling progress in a novel undertaking. Reasons for schedule stretch-out are discussed in this paper. The major factor in the LCT was the discovery by all participants of more technical problems than could have been foreseen. Also, the effor… more

The IEA Large Coil Task Test Results in IFSMTF

Description: The Large Coil Task (LCT) is an international collaboration of the United States, EURATOM, Japan, and Switzerland to develop large superconducting magnets for fusion reactors. The testing phase of LCT was completed on September 3, 1987. All six coils exceeded the design goals, both as single coils and in six-coil toroidal tests. In addition, a symmetric torus test was performed in which a maximum field of 9 T was reached in all coils simultaneously. These are by far the largest magnets (either … more

Superconducting Magnets for Fusion Reactors

Description: Superconducting magnets for fusion reactor applications are being developed in the U.S., Europe, Japan and the USSR. A substantial technological base already exists, but magnets for fusion face special problems and strong incentives for higher performance. In the U.S. high-field magnets for mirrors are being addressed by construction of the superconducting (NbTi) MFTF and by Nb/sub 3/Sn conductor development. Large toroidal field magnets for tokamaks are being developed through the Large Coil P… more

Description: The international Large Coil Task (LCT) has designed, built, and is testing six different toroidal field coils. Each has a 2.5- x 3.5-m D-shaped bore, a current between 10 and 18 kA, and is designed for stable operation at 8 T. Three coils are bath-cooled; three are cooled by forced flow of helium at supercritical pressure. One uses Nb/sub 3/Sn; the others NbTi. The test coils are equipped with voltage, temperature, magnetic field, flow pressure, strain, displacement, and acoustic emission sens… more

Summary of HRT Run 14

Description: A detailed study of HRT Run 14, which was abruptly terminated by the formation of a hole in the Zircaloy-2 core tank is presented. In this run the reactor was operated at high temperature and pressure for ten days from March 25 to April 4, 1958. Nuclear power operation extended from March 29 until April 4, when fuel solution leaked into the heavy-water blanket. The maximum power level attained was 6.4 Mw. The reactor equipment performance was satisfactory, except for the core vessel, but the nu… more

Conceptual design study for the ORMAK-F/BX facility

Description: From 5th symposium on engincering problems of fusion research; Princeton, New Jersey, USA (6 Nov 1973). Consideration is being given in the U S. to a large, injectionheated tokamak that could attain the zero-power Lawson criterion with H plasma in the late 1970's. The facility would be designed for subsequent replacement of some internal components and addition of shielding and containment to permit D-T burning experiments. An 8-manyear conceptual design study is to be accomplished in FY-1974 a… more

Design of superconducting toroidal magnet coils and testing facility in the USA

Description: In the U.S. Large Coil Program, three industrial teams are presently designing test coils to general specifications prepared by the Oak Ridge National Laboratory with guidance from USERDA. Each test coil is approximately half the bore size of reactor coils, being oval or D-shaped, with a bore of 2.5 x 3.5 m. The dimensions and operating requirements of the coils are identical for all test coils. The coils are designed to produce a peak field of at least 8 tesla at the winding of a selected coil… more

Procurement and testing of superconducting toroidal field coils in the large coil program

Description: As part of the development of superconducting toroidal field coils for tokamak reactors, the U.S. Large Coil Program was established to accomplish the design, fabrication, and testing of large coils of competing designs, under conditions approximating those in a reactor. Three U.S. industrial teams are under contract to design and fabricate at least one coil each, to guidelines and specifications established by the Program.

Role of the large coil program in the development of superconducting magnets for fusion reactors

Description: Three U.S. industrial teams are designing and will build one coil each to a common set of specifications. Coil specifications and test conditions were chosen to insure maximum relevance to fusion program needs. Each test coil will have a 2.5 x 3.5 m D-shape bore, will contain about 7 MA-turns, and must operate at a peak field of 8 T while subjected to pulsed fields up to 0.14 T in a test stand that can accommodate up to 6 coils in a compact toroidal array. Coils by General Dynamics/Convair and … more

Experience with operation of a large magnet system in the international fusion superconducting magnet test facility

Description: Superconducting toroidal field systems, including coils and ancillaries, are being developed through international collaboration in the Large Coil Task. Focal point is a test facility in Oak Ridge where six coils will be tested in a toroidal array. Shakedown of the facility and preliminary tests of the first three coils (from Japan, Switzerland, and the US) were accomplished in 1984. Useful data were obtained on performance of the helium refrigerator and distribution system, power supplies, con… more

Description of the Ibm-704 Code for the Calculation of Concentration Transients in the HRT

Description: The calculation of concentration transients caused by mixing in the interconnected three-body system of the fuel dump tanks, core and blanket has been coded for the IBM-704. The system of equations includes material balances, the dependence of critical temperature on core and blanket concentrations, and the effect of temperature (density) changes on flow rates. The controllable flow rates, the fuel dump tank weight and the initial conditions are input variables. Outputs include core and blanket… more

HRT Source Shield Calculations

Description: Calculations indicate that the proposed shielding arrangement will give a dose rate at the surface of the water tank of about 100 mrem per hr., practically all gammas. This is adequate for transportation and handling, but if the radiation actually proves to be this high, a storage location isolated from normal working areas must be provided. The isolation area need not be large, however, since the calculated dose rate at 10 feet from the shielded sources is only 3.5 mrem pr hr. For the short ti… more

A Study of Uranium Isotopic Ratio Information from the HRT

Description: Samples taken at low power ("no loss" conditions ) over a period from Run 12 to Run 21 were analyzes by mass spectrograph to determine uranium isotopic composition. Results conformed that part of the uranium inventory is at all times held up, out of solution, in the reactor and that there is limited isotopic exchange between dissolved uranium and uranium in solids.

Effects of Letdown Rates and Oxygen Injection Rates on Xenon Poison Level and Excess Oxygen Concentration in the HRT

Description: Calculations indicate that it is impossible, even at high oxygen injection rates, to insure an excess of oxygen in the HRT fuel solution if the bubble letdown rate is more than 1 or 2 liters per minute. If, on the other hand, no bubbles are allowed to form, a reasonable excess oxygen concentration can be maintained with an oxygen injection rate which would not tax the capacity of the off-gas system. The xenon poison will be reduced to less than 2% by liquid letdown alone, and if an iodine absor… more
