The 8.9 magnitude earthquake and following tsunami last week has seen Japan struggle as it battles to control the nuclear meltdown of power plants in the north-east of the country.

Fukushima nuclear power plant in particular has been closely scrutinised as reports flow in on the progress of the plant - Japan's nuclear board raised the nuclear alert level from four to five today. Explosions and reports of nuclear fuel rods melting at the power plant have meant progress on the situation has been closely followed.

Industry body the Japan Atomic Industrial Forum are currently publishing daily updates of the status of power plants in Fukushima which give great detail into the condition of each reactor. Ranked from a level of low to severe, the update records the conditions of core and fuel integrity, water level and containment amongst other key information. These are some of the most in-depth and recent records and show how the crisis is being handled.

The table below shows the status of the reactors in the Fukushima Daiichi (the largest of the Fukushima power plants) and is colour coded to show the severity. Green for low, yellow represents high and red shows those of severe significance as judged by the JAIF. We have used JAIF's update 13 as this is the most up to the minute data we can get.

A table of major incidents and accidents at the plants can be found in our spreadsheet as can the data for Daini, Onagawa and Tokai Daini Nuclear power stations. What can you do with this data?
