On 11 March 2011 several nuclear reactors in Japan were badly damaged by the 2011 Tōhoku earthquake and tsunami. The Tōkai Nuclear Power Plant lost external electric power, experienced the failure of one of its two cooling pumps, and two of its three emergency power generators. External electric power could only be restored two days after the earthquake.[2][3]

Selling uranium stockEdit

In February 2013 in an attempt to raise money to be able to pay back loans due in April 2013, Japan Atomic Power did sell part of its uranium-stock. Streamlining and selling the uranium would be needed to pay back 40 billion yen. After April 2013 the major shareholders were expected to guarantee the payments for some 100 billion yen in loans. Japan Atomic Power refused to disclose the buyer.[4]

Activities abroadEdit

Japan's first nuclear activity in a previously non-nuclear country will be four 1000 MW reactors at Ninh Thuận 2 Nuclear Power Plant. The feasibility study to be carried out by Japan Atomic Power Company.[5] Japan Atomic Power Company will also consult the project.[6][7] The plant will be built by a consortium, International Nuclear Energy Development of Japan Co, which comprises 13 Japanese companies.[8] The plant will be owned and operated by state-owned electricity company EVN.

Unit 1 is expected to be commissioned in 2021, unit 2 in 2022, unit 3 in 2024 and unit 4 in 2025.[5]
