A reader writes in describing the contents:

Report to NISA on units 1 ~ 3 thermometer reliability

(the NISA requested Tepco to write a report once a month):

Some of the thermometers not previously evaluated were found to be usable, and some were found to be broken. Some thermometers that were not connected to a digital recorder have been connected to a digital recorder.

According to the plot on page 126

Unit 2′s TE-16-114L#2 RPV BELLOWS SEAL AREA, newly connected to a digital recorder (on 8 March 2012) reached 100°C on 19 March 2012. (but it is not marked as “broken”).

TE-16-114L#1 is having a similar rising trend, reaching 83°C on 19 March 2012.

According to Google’s translation, the  <監視に使用可> alongside both the navy and burgundy lines means <Can be used for monitoring>.
