The secondary system pipe rupture occurred on August 9,2004, at Mihama nuclear power plant unit 3. Eleven workers, who were preparing for an annual outage that was to start from August 14^<th>, suffered burn injuries, of who five died. Pipe wall thinning was occurred by erosion corrosion. We experimented and analyzed the mechanism to damage. The results show that the ruptured pipe have the turning fluid and the unstable flow. However, the thinning speed and the rupture stress are in the normal range. We guess that the turning fluid and the unstable flow are only a characteristic generated by the piping construction.

This paper describes opinion how to apply intellectual property to the development of code and standards. Japanese enterprises have been grown by eager utilization of patents which have been originally introduced from America or Europe. However, this strategy should be changed because intellectual property should be reflected as international standards to be de-facto standard. JSME organized code and standards committee to develop systematic domestic codes to harmonize with foreign code and standards.

In Japan, there are four regulations which are related to pressure vessel. Technical standards of those and the Japan Industrial Standards in which allowable tensile strength of materials for pressure vessel is stated, have been established based on ASME code. Domestic standards have been revised in order to interface each other and to coordinate with the latest edition of ASME code. Recently, allowable tensile strength of the high chromium steels in the Thermal Power Standard Code has been reduced by review of long-term creep strength with the original analysis method. Self-made standard is of assistance to improve technobgy, performance and reliability of engineering products.
