Design Guide for Radioisotope Power Generator Pressure Vessels.
Abstract
The guide is the end product of an engineering investigation to establish criteria and inspection procedures to assure long term structural and watertight integrity for radioisotope power generator (RPG) pressure vessels. The suggested construction of the RPG consists of a cylindrical pressure housing with either two formed torospherical end closures circumferentially edge welded to the housing or a flanged housing to which a formed end closure is bolted. The materials of construction are comprised of alloys of nickel, copper and titanium with the Hastelloy alloy C-276 being the preferred choice. The design of the electrical penetrator follows that suggested in the 'Handbook of Vehicle Penetrators, Connectors and Harnesses for Deep Ocean Applications.' The testing requirements consist of design verification tests for the electrical penetrators and sequential hydrostatic and leak testing of the RPG pressure vessel. The hydrostatic tests should be performed at 1.5 times design operating pressure. (Author)
