TOKYO (majirox news) – Radioactive water has been found leaking into the sea through a 20-centimeter crack near the sluice gate of reactor No. 2 at the Fukushima Dai-ichi nuclear power plant, said TEPCO (Tokyo Electric Co and plant operator).

The water containing high levels of radioactive material had accumulated in a concrete pit. For the first time, radioactive water was confirmed to have leaked into the sea from the crippled plant. Water in the pit measured more than 1,000 millisieverts of radiation per hour, which exceeds the legal limit.

Workers will fill the pit with cement to seal the leak. The pit is for maintenance and storing electric cables.

The term sluice gate refers to an artificial channel for conducting water with a valve or gate to regulate the flow.

Japan pumps out contaminated water
The contaminated water lying on the floors of the turbine buildings connected to reactors No.1, 2, 3 and 4 at Fukushima Dai-ichi power plant will be removed tomorrow.

Today workers will empty the contaminated water from steam condenser storage tanks in the turbine buildings in order to pump out water from the floors tomorrow.

The tainted water has to be removed to allow the operation to cool the fuel rods in the reactor cores to move forward.

Monitoring radiation systems
TEPCO ( Tokyo Electric Co and plant operator) completed installing eight monitoring radiation detection systems yesterday at the plant to replace ones that were damaged by the earthquake and tsunami, which struck Japan on March 11.

The systems are for monitoring radioactivity and ionizing radiation, according to the safety agency.

IAEA specialists check sea water
Today ocean water specialists from the International Atomic Energy Agency (IAEA) will monitor sea water radiation levels.

The IAEA will dispatch two additional specialists to assist in solving the problems at the crippled plant. They will arrive April 4.

A team of 16 specialists have been in Japan since March 24 and 25 to help in monitoring radiation levels. The group of experts include radiation protection, food safety and safeguards department officials.

The IAEA was set up as the world’s “Atoms for Peace” organization in 1957 within the United Nations. The Agency works with its Member States and multiple partners worldwide to promote safe, secure and peaceful nuclear technologies, according to its site.
