Foundations in punched trenches at construction projects in chuvashin

Results are presented for tests on 27 foundations in punched (tamped-out) trenches (including some tested under repeated loading and when a long period had elapsed after their construction), which showed high technical-economic indices. Experience with their operation permits recommending wider use of this foundation construction method.Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 2, pp. 18–21, March–April, 1992.     

Measurement of the subcriticality of power-stressed reactors with an analog reactimeter

Conclusions A technique has been developed for measuring the effects of reactivity in a subcritical reactor with an analog reactimeter. It is based on the compensation of the current applied to the reactimeter input from the neutron detector. The compensation of current produced by neutrons of the subcritical multiplying assembly formalizes the algorithm for reactivity calculation, making it an adequate model of a reactor with a source and making it possible to determine the subcriticality without prior entry into the critical state. In this case the measurements are made in the presence of neutron sources characteristic of power-stressed reactors. The regular devices of the control and safety system could be used to produce unsteady variation of the neutron flux.All of this permits the proposed method to be extended to zero-power reactors and to power-stressed reactors. Once the subcriticality has been measured an analog of the neutron source is introduced into the reactimeter. This instrument measures the effects of reactivity in the subcritical state without the reactor being previously put into the critical state, monitors the entry of the reactor into the critical state by checking the reactivity, and makes all the measurements usually made with analog reactimeters. If the intensity of the source does not change during measurements (5–10 min) when chambers sensitive to rays (e.g., KNK-56 chambers) are used as neutron-flux detectors, then the accuracy of -ray compensation does not affect the results of the measurements.Translated from Atomnaya Énergiya, Vol. 45, No. 5, pp. 375–376, November, 1978.     

Lubricants on a mixed base. Principles for controlling the properties

Modern commercial oils and lubricating greases are primarily multicomponent disperse systems. Such products contain no less than 3 – 5 different components, and there can sometimes be 8 – 10 components. Since the 1930s, oils and other petroleum-based lubricants have been widely used in industry. Translated fromKhimiya i Tekhnologiya Topliv i Masel, No. 2, pp. 40 – 43, March – April, 2000.

Reliability of assessment of the proneness of soils to slump-type settlement

It is demonstrated that existing predictions of slump-type-settlement deformations are more than 1.5 times lower than the actual possible slump-type settlement of soils, which is observed under field conditions. Suggestions are given for determination of the coefficient of relative proneness to slum-type settlement, which adjusts noncorrespondence between predicted and actual slump-type settlements.

Power-generating unit with dual-loop sodium-cooled fast reactor and dual-wall steam generator

The results of a probabilistic analysis performed to validate the safety of AES-2006 designed for the site of the Novovoronezh nuclear power plant are presented. The requirements for the AES-2006 design are examined. The characteristic features of the AES-2006 design for the conditions at the Novovoronezh nuclear power plant site are described, including the diversity of the equipment and operating regime, passive systems, and scheduled maintenance of safety systems with the reactor operating at power. The scope of the probabilistic safety analysis performed at the development stage of the technical design is described. The important problems which must be solved in a probabilistic safety analysis for the designs of new nuclear power plants are discussed.

The pharmacokinetics of Kefzol in patients with acute pancreatitis when administered intravenously and endolymphatically

Pharmacokinetics was studied of kefsole administered by intravenous and endolymphatic routes to patients (n = 23) with acute pancreatitis. The studies made showed that intravenous route for the drug administration makes for a quicker entering of the antibiotic into the peritoneal exudate. Apart from these reasons, endolymphatic antibacterial therapy does not appear to avert the development of complications involving pus-formation/discharging in acute pancreatitis and does not seem to be essential in the complex of therapeutic measures to be applied for treating the above patients.
