    摘要： A pressurized nuclear-reactor core is surrounded by a burst shield having a side wall formed with a plurality of longitudinal passages in which are received longitudinal prestressing elements whose upper ends extend beyond the upper edge of the side wall. The cover is formed with a plurality of holes that register with the passages in the side wall so that the cover can be set over top of the side wall with the upper ends of the prestressing elements projecting beyond the cover. Each prestressing element is provided at its upper end with an anchor body which can bear in force-transmitting relationship either with the side wall of the burst shield through a sleeve received in the cover and having a lower end standing on the upper edge of the side wall and an upper end adjacent the anchor body, or with the cover by means of a removable nut screwed on to the anchor body and engageable in force-transmitting relationship with the cover. In use the anchor body is dimensioned to pass through the cover on the top of the side wall so that when this cover is to be removed the nut is unscrewed and the anchor body bears through the sleeve on the upper edge of the side wall in order that the side wall not be destressed.

    摘要： A pressure vessel apparatus for containing fluid under high pressure and temperature including pressure surges caused by in-vessel explosions includes a vessel main body, a vessel top body and a vessel head. Elongated tendons interconnect the vessel main body to the vessel top body and elongated tendons with removable anchors also connect the vessel head to the vessel top body. The tendons with insulated protecting sleeves connecting the vessel main body to the vessel top body are chosen to allow the vessel top body to temporarily separate from the vessel main body before the vessel head separates from the vessel top body. These tendons may be mounted directly, on springs, or on dampers in order to provide optimum (minimum) response to the postulated load cases. Reinforced and internally supported bellows are provided about a joint between the vessel main body and the vessel top body to prevent leakage from the interior of the pressure vessel apparatus upon liftoff of the vessel top body from the vessel main body. Continuously wound prestressed wire strands or bands are provided around the periphery of the vessel walls.

    摘要： A novel jacking system and method are provided for moving a cable through a sheath which includes opposite vertical portions connected by an intermediate arcuate portion. The cable is relatively heavy, being made up of the order of some 170 to 200 strands of high carbon steel wire, each approximately of the order of one-quarter inch in diameter. The total length of the cable is of the order of 500 feet while its weight is some 7 1/2 to 10 tons.

The test instrument is capable of sending a first wavelength to the optical sensor and receiving a second wavelength from the optical sensor, wherein at least one of the instrument or the processor is configured to analyze the second wavelength and output sensor measurement data for storage in the database. The processor is configured to calculate an amount of tensile loading which exists in the post-tensioned tendon, based on the sensor measurement data and the sensor baseline data, and to provide an output.
