0 Nikolaeva, A.; Nikolaev, Y.; Kryukov, A. Steel Fabrication. Safety is always paramount due to the enormous amount of energy stored inside a pressure vessel. Due to the thickness of the walls of the pressure vessels, thermal stresses arise as a consequence of the temperature gradient along the thickness of the wall. 0000003201 00000 n Sorry. Your submission has been received! The function of a power reactor installation is to extract as much heat of nuclear fission as possible and convert it to useful power, generally electricity. This energy could lead to serious consequences should any part fail. Cold cracking, also called heat-affected zone (HAZ) cracking, occurs during cooling when the stress of solidification causes the weaker solid metal adjacent to a weld bead to crack. Comparison of pre- and in-service inspection techniques in Belgium and Germany against the backdrop of Ultrasonic Indications found at the reactor pressure vessel of Doel-3. permission provided that the original article is clearly cited.

American Alloy Fabricators ensures a secure fit by rolling our dimpled jacket around the tank then plug welding the dimples to the vessel. A high value of the thermal stress is compensated, partially, by a high tensile strength. Chemical composition (mainly Cu, P and Ni wt.% contents), Note that from the first issue of 2016, this journal uses article numbers instead of page numbers. The corrosion of the reactor materials, in addition to the associated consequences, such as loss of thickness, formation of cracks, etc., entails that the corrosion products are strongly radioactive and are carried by the coolant towards the outside of the reactor. 98 0 obj <>stream Controlled Pressure Range: 5 to 500 psi.
