New decameter radiopolarimeter URAN- 2. NASA Astrophysics Data System (ADS)Brazhenko, A. I.; Bulatsen, V. G.; Vashchishin, R. V.; Frantsuzenko, A. V.; Konovalenko, A. A.; Falkovich, I. S.; Abranin, E. P.; Ulyanov, O. M.; Zakharenko, V. V.; Lecacheux, A.; Rucker, H. The description of the new decameter radiopolarimeter is submitted. It is created based on the phased array URAN- 2, which is the greatest decameter array in the world after UTR- 2, having the effective area about 3. MHz. Polarimeter works at the central frequency of 2. MHz in a band of 1. Hz and 0. 3 k. Hz. It provides reception of circular polarization waves by the horizontal crossed dipoles from any direction. Its sensitivity is ≈1. Jy. With the URAN- 2 radiopolarimeter polarizing characteristics of a sporadic radio emission of the Sun (bursts of II and III types), and Jupiter (L- and S- bursts) are investigated.

The obtained data will consist well with the results derived in adjacent frequency ranges. At research of the radio emission of Cyg A and Cas A the essential fluctuations of a degree of circular polarization (Stokes V parameter) of these sources radiations are found. This is caused, presumably, by ionosphere inhomogeneity. ![]() It is unique radiopolarimeter really working on so low frequencies. The URAN- 2 radiopolarimeter organically supplements unique Ukrainian system of URAN decameter radio telescopes. URANOUS IODATE AS A CARRIER FOR PLUTONIUMDOEpatents. Miller, D. R.; Seaborg, G. Datierung 900 Zahlen In Kanada ZastavaT.; Thompson, S. G. A process is described for precipitating plutonium on a uranous iodate carrier from an aqueous acid solution con. A plutonium solution more concentrated than the original solution can then be obtained by oxidizing the uranium to the hexavalent state and dissolving the precipitate, after separating the latter from the original solution, by means of warm nitric acid. COGEMA Experience in Uranous Nitrate Preparation. Sci. Tech Connect. Tison, E.; Bretault, Ph. Separation and purification of plutonium by PUREX process is based on a sequence of extraction and back extraction which requires reducing plutonium Pu IV (extractable form) into Pu III (inextractable form) Different reducers can be used to reduce Pu IV into Pu III. ![]() Early plants such as that for Magnox fuel at Sellafield used ferrous sulfamate while UP 1 at Marcoule used uranous sulfamate. These reducers are efficient and easy to prepare but generates ferric and/or sulphate ions and so complicates management of the wastes from the plutonium purification cycle. Recent plants such as UP3 and UP2 8. La Hague, THORP at Sellafield, and RRP at Rokkasho Mura (currently under tests) use uranous nitrate (U IV) stabilized by hydrazinium nitrate (N{sub 2}H{sub 5}NO{sub 3}) and hydroxyl ammonium nitrate (HAN). In the French plants, uranous nitrate is used in U- Pu separation and alpha barrier and HAN is used in Pu purification. Compared to sulfamate, U IV does not generate extraneous chemical species and uranyl nitrate (U VI) generated by reducing Pu IV follows the main uranium stream. More over uranous nitrate is prepared from reprocessed purified uranyl nitrate taken at the outlet of the reprocessing plant.

Uranous nitrate can be generated either by electrolysis or by catalytic hydrogenation process. Electrolytic process has been implemented in early plant UP 1 at Marcoule (when changing reducer from uranous sulfamate to uranous nitrate) and was used again in UP2 plant at La Hague. However, the electrolytic process presented several disadvantages such as a low conversion rate and problems associated with the use of mercury. Electrolysis cells with no mercury were developed for the Eurochemic plant in Belgium and then implemented in the first Japanese reprocessing plant in Tokai- Mura. But finally, in 1. La.

NASA Astrophysics Data System (ADS)Belov, A. S.; Ivanov, A. S.; Lozins'kyy, A. B.; Rashkovskiy, S. L.; Shepelyev, V. A. 2. 00. 6- 0. 8- 0. The decameter range VLBI network URAN consists of 5 radio telescopes including the world largest in the range - UTR- 2. They make up interferometers with the baselines 4. Large size antennas arrays (up to 2 km), electrically controlled over both coordinates, are used to increase the sensitivity and decrease the confusion and interference effects. The system of distributed preamplification with a high dynamic range and receivers with narrow IF bandwidths (2. Hz) have been applied in order to minimize the broadcast station interference. Studies with the URAN were carrying out for a number of years and several tens of radio sources have been already observed successfully. For successful prolongation of the investigations it is necessary to increase the sensitivity of the system since the reliable determination of the sources angular structure needs a high signal- to- noise ratio. The increasing of the antennas effective area is cost- intensive and it is impossible now. An alternative way is a broadening of the received band and/or increasing of the coherent integration time to boost the radiometric gain. At the decameter wavelengths the coherent integration time is significantly limited by the effect of the interplanetary and ionosphere plasma. Front- end facility of all the URAN telescopes is broadband so a new generation of wideband back- end equipment has been developed including receivers with wide bandpass, fast ADCs and a computer based data storage devices. New equipment, the algorithms of the interferences rejection and the data reduction methods will be described in the report. Applications of URANS on predicting unsteady turbulent separated flows. NASA Astrophysics Data System (ADS)Xu, Jinglei; Ma, Huiyang. Accurate prediction of unsteady separated turbulent flows remains one of the toughest tasks and a practical challenge for turbulence modeling. In this paper, a 2. D flow past a circular cylinder at Reynolds number 3,9. RANS (URANS). Some typical linear and nonlinear eddy viscosity turbulence models (LEVM and NLEVM) and a quadratic explicit algebraic stress model (EASM) are evaluated. Numerical results have shown that a high- performance cubic NLEVM, such as CLS, are superior to the others in simulating turbulent separated flows with unsteady vortex shedding. Project of the URAN array for registration of atmospheric neutrons. NASA Astrophysics Data System (ADS)Gromushkin, D. M.; Barbashina, N. S.; Bogdanov, F. A.; Kokoulin, R. P.; Ovchinnikov, V. V.; Petrukhin, A. A.; Stenkin, Yu V.; Khokhlov, S. S.; Shulzhenko, I. A.; Yashin, I. I. The project of a new setup is directed at the registration of atmospheric neutrons (URAN) generated by hadronic component of extensive air showers (EAS). The setup includes 7. EAS components: electromagnetic by the group passage of charged particles and hadron component by the thermal neutrons. The neutrons and charged particles are detected using a specialized scintillation composition made of granulated alloy of crystals based on the Zn. S(Ag) powder with an admixture of B2. O3.

Reynolds- Averaged Navier- Stokes (URANS) method and Large Eddy Simulation (LES) in single- fluid approaches to multiphase modelling, respectively. It is observed that the large- scale structures and characteristic periodic shedding predicted by the URANS with the modified SST k- ω turbulence model show a good qualitative match with the experimental observations but with quantitative discrepancies, such as a different cavity length and volume, and a different location of shedding. Compared to the URANS results, the LES results reproduce more details of unsteady dynamics with an improved quantitative agreement.
