Medium-Term Implementation Plan for Spent Nuclear Fuel Reprocessing

The Nuclear Reprocessing Organization of Japan (“NuRO”) executes its operations inaccordance with the Medium-Term Implementation Plan for Spent Nuclear Fuel Reprocessing
formulated pursuant to the “The Spent Nuclear Fuel Reprocessing Implementation Act” (“the Act”) and“Ordinance for Enforcement of the Spent Nuclear Fuel Reprocessing Implementation Act”. Ensuring thesafety is the overriding priority in executing its operations, and NuRO promotes them steadily andefficiently.

1) Timing, Location, and the Quantity of Spent Nuclear Fuel for Reprocessing
Pursuant to the provisions of Article 42 of the Act, after authorization is received from theMinister of Economy, Trade and Industry, NuRO entrusts the reprocessing services to Japan Nuclear
Fuel Limited (“JNFL”), which is the licensee of reprocessing activity as specified in the Law for theRegulations of Nuclear Source Materials, Nuclear Fuel Materials and Reactors (“Law for theRegulations of Nuclear Reactors”), and implements it at JNFL’s Rokkasho Reprocessing Plant.
The Rokkasho Reprocessing Plant is currently under construction and JNFL is proceeding toconstruct the plant with the aim of completing construction in the first half of FY2018. Therefore,
during the period until such time, NuRO appropriately manages the process control so that the plantis able to be completed as planned.
With regard to the quantity of spent nuclear fuel to be reprocessed, at the stage when theoperation plan and other arrangements are specifically defined after completion, NuRO will
formulate a plan prior to implementing the reprocessing under Japan’s principle not to possess
plutonium without specific purposes.

2) Timing, Location, and the Quantity of Plutonium for MOX Fuel Fabrication
Pursuant to the provisions of Article 42 of the Act, after authorization is received from theMinister of Economy, Trade and Industry, it is anticipated that NuRO will entrust MOX fuelfabrication (mixed-oxide fuel fabrication of uranium and plutonium (“MOX Fuel Fabrication”))
services to JNFL, which is the licensee for fabrication activity as specified in the Law for theRegulations of Nuclear Reactors, and will implement at JNFL’s Rokkasho MOX Fuel Fabrication
Plant.

The Rokkasho MOX Fuel Fabrication Plant is currently under construction, and JNFL isproceeding to construct the plant with the aim of completing construction in the first half of FY2019,
Therefore, during the period until such time, NuRO will appropriately manage the process control sothat the plant is able to be completed as planned.
With regard to the quantity of MOX fuel to be fabricated, at the stage when the operation planand other arrangements are specifically defined after completion, NuRO will formulate a plan prior toimplementing MOX Fuel Fabrication under Japan’s principle not to possess plutonium without
specific purposes.

3) Regarding the Implementation of Other Activities related to Reprocessing
NuRO will appropriately store and manage radioactive waste separated as a result of previous
reprocessing and radioactive waste generated as a result of previous commissioning test, including
waste generated in the future, at JNFL’s Rokkasho Reprocessing Plant until they are delivered forfinal disposal.
NuRO will appropriately continue to store and manage radioactive waste from overseas atJNFL’s Waste Storage Management Facility until it is delivered for final disposal for a period of 30
to 50 years, which is the period of time necessary for cooling the waste. Also, NuRO willappropriately store and manage waste to be returned from overseas in the future at Waste Storage
Management Facility until it is delivered for final disposal.
With regard to decommissioning the plants described in numerals 1, 2 and 3, NuRO willcommence after operation of such plants are terminated.
