Fukushima Daiichi NPS Prompt Report (Aug 09, 2013)Tritium Density Result of Water Quality Survey inside the Port of Fukushima Daiichi NPS (Follow-up Information 33)
This is follow-up information on the latest situation concerning the detection of high densities of Tritium and Strontium in the observation hole at the east side of the Unit 1-4 Turbine Buildings of Fukushima Daiichi NPS.
We would like to make an announcement on measurement results of the γ tritium density in water sampled on August 8 from the newly installed groundwater observation hole No.0-1 (east of Unit 1 Turbine Building), as we obtained the results.
<Groundwater observation hole No.0-1> (new)
- Sampling on August 8:
Tritium 23,000Bq/L
This tritium density in the water from the groundwater observation hole No.0-1 was high compared to the densities (several hundred Bq/L) in the groundwater observation holes No.2-1 and No.3-1 measured in the past. Therefore, we will conduct measurement and sampling again on this location.
We are continuing to tackle this problem in such manners as to intensely bring forward implementation of contamination prevention measures such as foundation improvement work to the bank protection, and comprehensively intensify the monitoring by using the results of additional boring to drill additional locations, and the analyses results on seawater at such locations as the port interior and the water outlets.
