In 2018, Tokai Reprocessing Plan (TRP) shifted to the decommissioning stage. In order to proceed with steady decommissioning work, TRP effort to enhance project management function. This paper describes the establishment and role of the Decommissioning Project Management Office, effectiveness of applying the project management tool and its utilization concept, and the method of materialize the equipment dismantling plan.

Accidental actions on building structures involve impact and explosion loads. The design loads due to impact are determined by experiment data, impact simulation and energetics approach. These loads are presented in the form of load-time (F-t) curves caused by collision and explosion. It is assumed that the structure is rigid and immovable and that impacting body absorbs all the energy (i.e., hard impact condition is supposed), because this assumption gives conservative results in general. Responses of individual structural members directly-subjected to an impulsive load are evaluated. These responses are classified into three types; impulsive response, dynamic response, and quasi-static response. The maximum responses are basically estimated by direct integration method with a single-degree-of-freedom (SDOF) model. The procedure of the SDOF modelling based on the classification of types of members and failure modes is proposed in AIJ guideline.

Though design guidelines for earthquake and wind loads are specified for buildings, the guideline for impulsive load as explosion and impact is not specified yet in architectural field. This document corresponds to Chapter 8 of the book titled "Introduction to Shock-Resistant Design of Buildings" which made towards the impact design guideline. Some design examples are presented to illustrate the applicability of the tentative guideline for impulsive loads. Two buildings - a steel frame and a reinforced concrete frame building structures - located at the corner of a crossroads are selected. Dynamic responses and the corresponding damage states are illustrated for the cases of two buildings subjected to impact loads due to road vehicle crashes, internal and external explosions. The idea has been shown in this document are those that can be applied to nuclear facilities.

WG4 was newly established under SC3/TC98 (Bases for design of structures) in 2015 to formulate the international standard ISO10252 for accidental actions by artifacts. Accidental action refers to an impact load that acts on the structure accidentally as a result of a collision with an automobile, a train, an aircraft, and so on or a gas explosion that occurs indoors or outdoors. Collisions of flying objects caused by tornadoes or volcanoes are also included in accidental action. The guides established in recent year, for example, the Impact Assessment Guide on Tornado for NPP, which was established in June 2013, require impact assessment for nuclear facilities caused by flying objects. This international standard presents the basic concept for calculating impact loads in these impact assessments. This presentation will introduce examples of design load for some kinds of impact action.

The Architectural Institute of Japan (AIJ) published a book titled "Introduction to shock-resistant design of buildings" on the theme of accidental actions in Jan. 2015. In addition, based on this book, a new chapter on impact loads was added to the revised version of "Recommendations for Loads on Buildings" in March 2015. In this presentation, the outline of the "Introduction to shock-resistant design of buildings" will be outlined. And the activities by AIJ on the shock-resistant design in a concrete and rational manner after the publication of this book will be introduced.
