State-run Taiwan Power Co must draft a plan for the decommissioning of the first reactor at the Chinshan Nuclear Power Plant, within three years, The Taipei Times reported, citing a senior official at the Atomic Energy Council.

According to Chiu Tzu-tsung, head of the regulator’s Radiation Monitoring Centre, Taipower has until 5 December 2015 to show the regulator how it plans permanently and safely shut down the reactor in 2018, as scheduled.

Taipower must give details on the costs and manpower it will need to handle the decommissioning, and how it intends to dispose of the reactor, the newspaper reported.

If Taipower fails to submit the plan on schedule, the company will face a fine of between NT$500,000 and NT$2.5 million (US$17,200 and US$85,900), and be given a new deadline, according to the reports.
