Transferring water in the basement of the Unit 1 turbine building to the condenser coils

2011-4-6

 On 3rd April, transferring of consuming water by means of the system one condenser toward condenser coils storage space tank was began in preparation for transferring consuming water within basement in the system one turbine constructing toward condenser. On 2nd April, transferring of consuming water by means of the system a few of condenser toward condenser storage space tank was began in preparation for transferring consuming water within basement in the system one turbine constructing toward condenser coils.
TEPCO has identified a feasible leakage trail by means of the Turbine constructing of system a few of toward sea by means of a sequence of trenches/tunnels utilized to provide energy toward sea consuming water ingestion pumps and provide of program consuming water toward reactor and turbine buildings. On 4th April, a tracer was utilized in an make an effort to decide in which the consuming water was coming from. So far, the tracer has not been observed within consuming water leaking in to the sea.
In system one clean consuming water may be continually injected in to the reactor stress vessel by means of feed-water collection at an indicated flow demand of 6 m3/h producing utilization of the temporary electrical pump with off-site power. In models a few of and three clean consuming water is getting injected continually in to the RPVs by means of fire extinguisher collection at indicated prices of 9 m3/h and 7 m3/h producing utilization of the temporary electrical pump with off-site power.
In system one the indicated temperatures on the feed consuming water nozzle in the RPV decreased from 243 °C to 234 °C and on the bottom of RPV stable at 115 °C. The RPV stress indications are fluctuating and Drywell stress is stable. The RPV stress indications for the a few of channels are diverging. For system a few of the indicated temperatures on the feed consuming water nozzle in the RPV is stable at 142 °C. The temperatures on the bottom of RPV was not reported. Indicated Drywell stress remains to be at atmospheric pressure. In system three the indicated temperatures on the feed consuming water nozzle in the RPV is stable at 114oC and on the bottom of RPV is about 85 °C. The validity in the RPV temperatures measurement on the feed consuming water nozzle is even now below investigation.
In system a few of extra consuming water was injected by means of the invested condenser coils method collection toward invested fuel swimming pool with a temporary pump on April 4. In system 4, 180 T of clean consuming water was sprayed toward invested fuel swimming pool by concrete pump on April 3rd.
There may be no alter of placement on models 5-6 as well as the standard invested condenser coils storage space Facility.
