The main thrust of this meeting was the interpretive techniques currently being applied to radiography (both X and N). The X-ray advances discussed were in many instances an adaptation of recent medically oriented techniques, particularly edge enhancement, color contrast enhancement, and various derivations from laminography and tomography. It is very surprising that so much time has passed before these techniques have been applied to commercial radiography. At General Atomic we applied edge enhancement and color contrast enhancement to our NR work as early as 1971. While these techniques have been known in X-radiographic circles for several years, there is still little application. Even less application has been made in the NR field. At this meeting, one of the first applications of laminography to commercial X-radiography was described and is available from Medicom Corp. In Weymouth Landing, Massachusetts. Although a simplistic application to inspection of ersatz fuel bundles has been made by

The objective of this study program is to establish aset of recommendations for a neutron radiography facilitywhich is contemplated as part of the PNC's Fuel MonitoringFacility at Oharai,Ibaraki-ken. This plan has beenproceeded by exchanging requests,comments and/orrecommendations between PNC and GAC.Follwing are the main items which have been studiedand discussed in the report:1. Status of NR technology in U.S.A.2. SAR and design of the standard TRIGA reactor3. NR facility requirements and its ground rules

The most common impurity in liquid sodium systems,oxygen,forms a crystalline precipitate at temperatures above thefreezing point of sodium. This property allows purificationof liquid sodium by a cold trap,a device in which thetemperature of the liquid sodium is reduced to near itsfreezing point and the impurity crystals are removed.Nitrogen,hydrogen and carbon,and many other impuritiessuch as fission products,corrosion products and tritium arealso removed by cold trapping,at least to varying degrees.The design and operation of liquid-metal cooled reactorstypically require several different cold trap applicationsfor purification of the reactor coolant loop,the inter-mediate coolant loops,and auxiliary systems such as fuelstorage,fresh sodium,etc. For each application,differentduty cycles are imposed from time to time by maintenance,incidents,steady-state operation,and other operationalevents. Different trap designs for specific applicationsare therefore required.Cold traps in the interm

This working group has been translating into Japanese the publication "Practical Guidance for Engagement with the Public on Radiation and Risk" by IRPA in 2020. This publication was made with the theme of public understanding, which was one of key issues that the consultation by IRPA to its member societies identified as most necessary in the radiation protection system. The translated guidance is supposed to be distributed to radiation protection experts and relevant communities in Japan who may be interested in public understanding. The purpose of this symposium is to share the working progress and important points of the guidance.

The WG has translated the "Practical Guidance for Engagement with the Public on Radiation and Risk" ("IRPA Guidance") issued by the International Radiation Protection Association ("IRPA") to its member societies in 2020. "The content of the IRPA guidance was presented at a symposium organized by the Health Physics Society of Japan in June 2020. The content of the IRPA guidance was presented at the Health Physics Society planning symposium held in June 2020, where many experts attended and provided feedback. In this planning session, we will focus on public engagement and related specific examples and situations related to public engagement.
