A prefabricated in-core nuclear plant instrumentation chase concrete form is provided that has integral embedment plates at the locations where the in-core instrumentation guide thimble supports contact the walls of the chase. In some embodiments, such nitric oxide-releasing compounds are macromolecules such as dendrimer and co-condensed silica. Also, the effective compression ratio of the compression stroke cylinder is decided based on a piston position at engine restart. A conducting gate layer is placed over the upper silicon dioxide layer. The female mold couple includes a female mold core. The system can include a catheter having a tip portion that can generate sound waves which can be detected by auscultation devices which allows the position of the catheter tip to be triangulated.
