Unit 2 Inlet Bar Screen
Explanation:
To minimize migration of contaminated water to the open sea, on the ocean-side of the ***Inlet Bar Screen of Unit 2***, the two temporary steel plates (3 plates in total) were installed to stop water from leaking out of the inlet bay (around 08:30 until 10:00, 13 April). In addition, a silt fence to prevent the spread of the contaminated water was installed in front of the Screen of Units 3 and 4. (13:50 UTC, 13 April).

The transfer of contaminated water from the trench of the Unit 2 Turbine Building to the condenser started on 12th April and continued on 13th April until approximately 660 tonnes were transferred.

To minimize the movement of contaminated water to the open sea, temporary boards to stop water (3 steel plates in total) were installed on 13th April on the ocean-side of the ***Inlet Bar Screen of Unit 2. ***

Silt fences have also been installed in the inlet canal and in front of the ***Inlet Bar Screens*** of Units 1, 2, 3 and 4. On 11th April, a silt screen was installed at the southern end of the inlet canal. The installation in front of the Inlet Bar Screen of Units 3 and 4 was completed on 13th April and for Units 1 and 2 on 14th April.

As of 14th April, white smoke was still observed coming from Units 2 and 3. White smoke was also observed coming from Unit 4 on the 14th April.
