HTGR gas turbine power plant configuration studies

Conference ·
OSTI ID:4307464
From winter meeting of American Society of Mechanical Engineers; Detroit, Michigan, USA (11 Nov 1973). The High Temperature Gas Cooled Reactor (HTGR) gas turbine power plant concept combines the existing design HTGR core with a closed-cycle helium gas turbine power conversion system which is driven by the reactor coolant helium. The use of a gaseous working fluid enables the heat rejection to be well matched to the capabilities of dry cooling towers which can minimize environmental impact while conserving water resources. The objective of the studies reported was to establish the main features of the reactor and gas turbine power conversion system layout for subsequent preliminary design studies. Initial decisions were made to adopt an integrated arrangement (gas turbine loops located within the prestressed concrete reactor vessel) embodying multiple turbomachinery loops, based on a non-intercooled cycle with a high degree of heat recuperation. The plant configuration studies consisted of the preparation and evaluation of alternative designs incorporating various orientations of the turbomachinery and heat exchangers with respect to the reactor core and primary and secondary containment systems. Design studies were made of single-shaft and split-shaft turbomachinery in conjunction with both horizontal and vertical generators and were evaluated on the basis of control, safety, and maintenance. 7 references.
