Steel liner

Similar behaviour occurs when trying to locate voids in concrete cast behind steel plates, e g. the steel liner in nuclear containment walls. Our own experience has shown that in the case of a steel liner (encast at depth 250 mm) the reflected compression waves are dominant regardless of the condition of the concrete behind the plate.

MKI The Mark I containment consists of two separate structures (volumes) connected by a series of l.irae pipes One volume, the dry well, houses the reactor vessel and primary system components. The other i oUmic is a torus, called the wetwell, containing a large amount of water used for pressure suppression and as, i heai sink. The Brunswick units use a reinforced concrete structure with a steel liner. All other M,uk 1 cnni.un ments are free-standing steel structures, The Mark I containments are inerted during plant oper.mon i. prevent hydrogen combustion. 

Issues related to HE of steel liner may still exist however, due to the thin steel liner carrying lower stresses, potential for hydrogen cracking could be reduced. 

The main principles are to store gas at high pressures (15-25 MPa) in lined rock caverns at relatively shallow depth (100 - 200 m). Gas-tightness is provided by a steel liner. The liner is supported by a concrete layer, the purpose of which is to transmit the pressure forces from the liner to the rock. The role of the rock is to resist to the gas pressure. 

A steel liner reinforced with a steel I-beam baffle was installed in the LEAP tank for secondary containment of the experiment. The primary liner was a 0.64-cm thick welded seam high-density polyethylene (HDPE) liner installed within an outer steel liner. Baffles in the steel liner were backfilled with pea gravel and contained eight fully screened 5-cm-inner-diameter (ID) wells. These wells could be used for leak detection as well as mitigation by inducing a hydraulic gradient into the tank. The finished interior dimensions of the tank were 8.5-m wide, 8.5-m long, and 3-m deep. 

Supercritical gas extractions Method B. Extractions were carried out in a 500 ml rocking autoclave fitted with a stainless steel liner. The Internal volume of the autoclave with liner was 420 ml. The autoclave was charged with coal and solvent, heated to and maintained at temperature for 1 h. The residue was washed out of the cooled reactor with acetone, filtered, washed with pyridine and then acetone and dried under vacuum. In some cases, g.c. analyses of the gases in the cooled reactor were carried out. 

Na/S cell There are various cell designs and details can be found elsewhere [7]. The principle of operation is illustrated in Fig. 4.28 and a schematic of one design of cell shown in Fig. 4.34. The cell contains just the amount of sodium for it all to be combined with the sulphur for complete discharge. The small space between the stainless steel liner and the electrolyte contains a fine stainless steel mesh which, by capillarity, can raise the height of the liquid sodium which enters the gap through the small hole at the bottom of the liner. The sodium can be pulled to a height of at least 200 mm at 300 °C.

Many of these approaches have been used in mixed potential models to predict the behavior of copper nuclear waste containers in a compacted clay environment (22), and to predict the corrosion rate of nuclear fuel inside these containers once they have failed and water allowed to contact the nuclear fuel (U02) wasteform (6). The container is lined with a carbon shell liner to give it mechanical integrity. Consequently, when the container floods with water on failure, two corrosion processes are possible, corrosion of the U02 wasteform (conservatively assumed to be unprotected by the Zircalloy cladding within which it is encapsulated) and corrosion of the carbon steel liner. The reaction scheme underlying...

The barrel Is composed of a steel liner 3/8 00 and an aluminum outer sleeve that Is 3/4 OD at the mark. You want to cut through the outer barrel only, so draw a line on the hacksaw blade 3/16 above the teeth. Cut the barrel at the file mark, rotating It as you go, until the entire cut is 3/16" deep. If you saw slowly, you can feel when you reach the steel liner,...
