With regard to FY2018, plans were underway for Hamaoka NPS to transport low-level radioactive waste to JNFL in May this year.

However, water drops and coat peelings were found at the bottom of one of the 960 low-level radioactive waste (drums) Hamaoka NPS handed over to JNFL this March, and investigations are therefore underway at the moment. There had been other low-level radioactive waste scheduled for transportation in May, but a decision was made to deliver them after factoring in results of future cause investigations on the peeling event.

The drum in which personnel found coating spall will be sent back to Hamaoka NPS for detailed investigations.The remaining drums that were handed over to JNFL in March 2018 will likewise be returned if outcomes of future checks lead to determining the need for detailed investigations.

The changed transportation timing will be announced as soon as they are decided.
