The regulatory standards for nuclear facilities were revised, reflecting the lessons learned from Fukushima-Daiichi NPS accident. Many requirements for safety measures, in case there are natural disaster or severe accidents, are added for nuclear fuel cycle facilities. Aiming achievement of the nuclear fuel cycle, various safety measures for conforming to new regulatory standard and improving, have been taken at Rokkasho reprocessing plant.

The site tour which is a part of CPD events regarding the issue concerning the radioactive waste from nuclear facilities was organized in autumn 2019, and we visited the facilities related to the specified waste due to the Fukushima-Daiichi Nuclear Power Plant accident in spring 2020. The tours made us reacknowledge the impact of radionuclides on environment at accident, the importance of the management of nuclear facilities under the basic premise of ensuring safety, the necessity of the discussion based on the common understanding, and that would be contributed to find the solution of those issues.

Since the FUKUSHIMA-DAIICHI Nuclear Power Plant accident, a significant issue to develop human resources for nuclear and radiation technology has been growing up. A strong effort will be made, based on the serious experiences of troubles/accidents, to restore social confidence by developing engineers having high sense of ethics beyond logic of organization.

The Atomic Energy Society of Japan (founded in 1959; AESJ) establishes the Code of Ethics and organized an ethics committee as a permanent committee in 2001. The mission and the purpose of the Ethics Committee activities permeate through the AESJ members for code of ethics. Members' sense of affiliation with AESJ is not as high as IPEJ. This paper introduce the significance, contents and issues of ethics activities at AESJ.

The verification activity and training of operation in the Fukushima-Daiichi Nuclear Power Station are more important than another Nuclear Power Station. At the JAEA Naraha Remote Technology Development Center, it has being carried out the development work to apply to the decommissioning work by using the full sized mock up and VR system which is built based on location surveying data of inside the reactor building. It is able to contribute to the decommissioning more reliably and efficiently.

We visited Onagawa NPP and discussed with the workers, for study of good practices at this plant, avoided severe accident, when the 3.11 earthquakes and tsunami disaster occurred. It was learned a part of background of the good practices, by discussion about organizational culture included in attitude for safety, philosophy of management, inheritance technology, and so on. It is important that we inform the knowledge leading safety culture analyzed from their experience to public, as professional engineer.

Current status and issues of Fukushima prefecture after the Fukushima-Daiichi Nuclear Power Plant accident were described both of the health effects of radiation exposure and the social effects. Important activities for revitalization in Fukushima are tackling of social task in Fukushima and understanding of correct radiation risk outside Fukushima. The role of the nuclear and radiation professional engineers for this activity was considered.

Five years have passed since the accident of the Fukushima Daiichi Nuclear Power Station. The Nuclear and Radiation section of the Institute of Professional Engineers hosted a site tour of the plant to make themselves sure what is going on in it and to disseminate information about it. The conditions of landscape during traveling between the gathering place and the plant, each reactor, contaminated water treatment, site, and work environment improvement will be reported.

It is one of the important subjects for decommissioning to establish the safe and effective waste management. Research and Development programs on the waste management for Fukushima-Daiichi as it differs from normal practices are conducted by IRID. We show the outline of the lecture presented by Mr.Miyamoto, Deputy Director of IRID.

For decommissioning the Fukushima-Daiichi Power Plant, various studies and activities have continued. In this paper, it was mainly described the status of research for fuel debris retrieval with remote technologies, which was the most difficult challenge, introduced in CPD program. Investigation and analyzing for debris condition in each reactor have done. Various researches and developments for the way of fuel debris retrieval with remote technology, including in access route, from the top or side, have continued with the result.

This serialization article will describe Continuing Professional Development (CPD) of the nuclear and radiation professional engineers for Fukushima support activity after the Fukushima Daiichi Nuclear Power Station accident. In this first article, the structure and the outline of the serialization are noticed. Based on the lecture of CPD, issues and risks of the decommissioning plan of the Fukushima Daiichi Nuclear Power Station are manifested.

Atomic Energy Society of Japan (AESJ) has researched descriptions regarding energy, nuclear power and radiation in textbooks of school education for about 20 years, since 1995. In the activity on 2014 Japanese Fiscal Year(JFY), the research about textbooks to Nuclear and Radiation Group of IPEJ in attendance with professional engineers was requested and implemented. The research focused on the descriptions about the accident of Fukushima-Daiichi Nuclear Power Plant that was passed 4 years, was implemented. As the result, AESJ pointed out that some descriptions should be revised objectively, and there were some misleading descriptions, etc.

Various analysis reports focused on Fukushima Daiichi Nuclear Power Plant disaster have been published from government, national diet, private group and Tokyo electric power company. Japan Health Physics Society (JHPS) analyzed these reports on perspective of radiation protection, and has reported towards the national and international society as "second-order recommendation report". What are radiation protection issues that have been found from these analysis reports? What is the direction of the goal of radiation protection system at the time of nuclear accident? From the results of these analyzes, many challenges have been found in current nuclear disaster prevention system.

In a reprocessing plant, some apparatuses are in severe corrosive condition, like exposure to boiling nitric acid. Safety functions, like fire prevention on organic solvent, are needed on some apparatuses. To maintain the apparatuses and functions, various inspections are performed. The features of the maintenance in high dose, are represented in experiences of remote operation. The way of decommissioning of Tokai Reprocessing Plant has been indicated last year. But importance of maintenance will not change, because the apparatuses for treatment of high level liquid waste will be used for long term. Continuing development of remote maintenance technology and contribution to decommissioning Fukushima Dai-ichi NPP are expected.

There seem to be a problem, though, the people tend to take safety and relief (Anzen-Anshin) as the same concept, without correctly understanding the concept of risk. It is an important issue, then, for the specialists of science and technology how to secure safety as well as how to inform the public about safety. Here I consider what nuclear and radiation professional engineers should do to transfer the information on safety to achieve Anshin (relief) among the public in Japan after the Fukushima-Daiichi Nuclear Power Plant accident.
