Tepco secretly increased the water amount to inject to reactor2.
Having the heating gauge indicate extreme temperature, Tepco and NISA has been suspecting the gauge was out of order.
On 2/18/2012, Tepco officially abandoned the gauge and decided to pick up another one, which is located at 135° far from the first one. It’s indicating about 30℃.
However, Tepco increased the water amount to inject on 2/15, and still haven’t decreased the water amount.
According to their plant parameter data, they were injecting 17.5 tones / h of water until 12:00 2/15, but the data of 6:00 2/16 tells they inject 17.6 tones /h, which was increased by 0.1 tone / h.
No explanation is given from Tepco and the data of 12:00 2/18 tells they are still injecting 17.6 tones /h.
