Abstract

The 51st German Plant Protection Conference was held by the Federal Biological Institute of Agriculture and Forestry [BiologischeBundesanstaltfür Land- und Forstwirtschaft] in Halle/Saale from 5th to 8th October 1998. The attendance of over 1,000 registered participants reflected the continued lively interest shown in the conference. Some 330 oral contributions, assigned to the various sections, were presented in five parallel sessions.

Projects of High-Temperature Nuclear Reactors

(Overview. Part 2) / Augstas Temperatūras Kodolreaktoru Projekti

J. Ekmanis, E. Tomsons and N. Zeltiņš

Part 2 of the overview gives emphasis to the projects of high-temperature NRs, whose development is an area of active engagement for the specialists from the USA, France, Japan, Russia, China, the Netherlands, and Germany. Projects of several powerful NRs of the HTGR type for commercial use had been worked out in the USA and Germany already by 1970 but not yet implemented.
