This report describes progress in the design of and process applications related to the 2240-MW(t) HTGR-SC/C, the monolithic HTGR-PH, and the 250-MW(t) HTGR-MRS/PH and HTGR-SETS plant concepts. The HTGR core design program is reported, including proposed solutions to the thermal-hydraulic core fluctuation phenomena experienced in the FSV HTGR design. Detailed descriptions are presented on improvements in NSSS components, including the PCRV and thermal barrier, reactor internals, steam generator, main and auxiliary circulators, and helium service system and auxiliaries. The expected performance of the HTGR-SC/C NSSS is presented, and the progress on priority technical issues related to nuclear heat supply integration is discussed. Plant system dynamics, availability, and maintainability studies are reported along with goals and best estimates for achieving them. Licensing, safety investment, and reliability study results are also presented.
