LEROY, N.Y., Sept. 26, 2001 Tokyo Electric Power Company, one of the world’s largest power utilities, is featuring its thermal hydraulics research on its web site.
Included in this report is Helios Energy Technologies’ (HEETech) HelioPAC™, a system which is being integrated into the Advanced Boiling Water Reactor (ABWR) feedwater train to improve plant reliability, life cycle cost and to simplify the feedwater system.
The HelioPAC™ (U.S. Patent No. 4,569,635) is the most advanced steam injector device available and has received international recognition as having excellent potential for improving Rankine Cycle performance and enhancing nuclear plant safety.
TEPCO has collaborated with Toshiba Corporation, Yokohama, Japan on the development of the Steam Injector based ABWR feedwater heating system since 1999. For over a decade, Toshiba and HEETech have worked jointly on the development of several nuclear plant safety innovations and this most recent application closely mirrors another of HEETech’s patented processes. U.S. Patent No. 5,794,447 and European Application No.97916857.2 describe HEETech’s proprietary method for implementing HelioPAC technology into the steam plant power cycle to increase net cycle efficiency, reduce capital cost and lower O&M expenses.
Dr. Tadashi Narabayashi, Senior Specialist of Reactor Components at Toshiba’s Nuclear Engineering Laboratory presented a technical paper at the SMiRT-15 Conference (1999) in Seoul, South Korea describing the proposed nuclear feedwater heating system. The paper, entitled Development of Steam Injector for Next Generation Reactor , was coauthored by distinguished researchers from TEPCO as well. Dr. Narabayashi has presented many other papers related to Toshiba’s ongoing HelioPAC studies, particularly with respect to their very successful passive safety applications for the Japanese Boiling Water Reactor.
