OREANDA-NEWS. Electric Power Development Co., Ltd. ("J-POWER") hereby gives notice that J-POWER has concluded formulation of measures for reinforcing safety at the Ohma Nuclear Power Plant.

Based on the new safety standards, measures for reinforcing safety have been examined, including design reviews.

For design basis to prevent severe accidents, J-POWER will further strengthen earthquake and tsunami resistant measures, and for the newly established measures against severe accidents, J-POWER will incorporate measures to prevent core damage and containment vessel failure, and install a specified severe accident response facility as a countermeasure to terrorist attacks such as airplane crash.

Standard seismic motion: 650 cm/s2 (previously 450 cm/s2)
Design basis tsunami: Highest sea water level: T.P. +6.3 m (previously +4.4 m),
Lowest sea water level: T.P. -4.1 m (previously -3.8 m)

In the Ohma Nuclear Power Plant, all measures are being implemented during construction, including the specified severe accident response facility which is subject to transitional measures for five years after the regulations are enforced, to create a safe power plant.

The construction works for measures for reinforcing safety that have been formulated this time are scheduled to commence in November 2015 toward completion in December 2020. The planned construction budget is approximately 130 billion yen.
