I spotted this across my twitter feed from the usual reliable sources.

1. ENENEWS: BREAKING: 82°C at Reactor No. 2 — Keeps rising even after injection of more water — Tepco “set to dump in boric acid”
2. EX-SKF: JUST IN: #Fukushima Reactor 2 RPV Bottom Temperature at 82 Degrees Celsius
3. Enformable: Temperatures at Fukushima Daiichi reactor 2 continue to rise

Editor's Note: I did confirm as below that the trend of the lower reactor (shown as "B" in the charts) temperature is trending down for the last 100 days.

NISA has been announced that the plant parameters (reactor state), the temperature of the reactor has been graphed.
You can check the daily water temperature, pressure and radiation dose of No. 1-5, Fukushima Daiichi nuclear power reactors.
As soon as the data is published and updated as the chart.
All information is automatically graphed the information that is published by CSV. No. 4 is the value of CSV information has not been published, not shown.
Meaning of the terms in the chart below. A reactor feedwater nozzle temperature ... B ... lower temperature pressure vessel design temperature of the reactor ※ (maximum temperature resistance) is indicated by a dotted line at 302.

※ The value of the graph shows the maximum absolute value of the day.
