Heavy-Section Steel Irradiation Program: Foreign Trip Report, October 21, 1989-November 11, 1989.

摘要

The traveler served as a member of the delegation from the US Nuclear Regulatory Commission in an information exchange meeting on nuclear safety with the Czechoslovak Atomic Energy Commission in Prague, Czechoslovakia, October 23--27, 1989. The exchange included meetings at the Institute of Nuclear Research in Rez, visits to the Skoda Concern in Pilsen and the Dukovany Nuclear Power Plant, and meetings at the Czechoslovak Commission for Nuclear Energy in Prague which resulted in the signing of a protocol agreement. From October 30 to November 6 the traveler presented lectures and participated in discussions on radiation effects and fracture mechanics at the Harwell Laboratories, Oxfordshire, United Kingdom; at the institute for Materials, Stuttgart, Federal Republic of Germany; at the Institute of Technology, Trondheim, Norway; and at the Royal Institute of Technology, Stockholm, Sweden. The effects of radiation on nuclear pressure vessel and support steels, and the conduct of experimental fracture mechanics programs to evaluate structural integrity were the primary topics of discussion during those visits. Additionally, the traveler attended workshop meetings of the International Group on Radiation Damage Mechanisms in Pressure Vessel Steels (IG-RDM) in Helsinki, Finland. This workshop of the IG-RDM was the first technical meeting of the IG-RDM following its installation on October 7, 1988. The meetings resulted in detailed exchange of technical progress between participants, identification of specific areas requiring continued research, and procedures for collaboration and sharing of resources.
