Overview

Safety Principle

The most critical aspect of radioactive waste management is how to manage the radiation, and it becomes the safety standard of the radioactive wastes.

Safety Management of Radioactive Waste

The most critical aspect of radioactive waste management is how to manage the radiation, and it becomes the safety standard of the radioactive wastes.

Safety Principle(Safety Regulations by Government-Secure Inspection, Regulations from Site Selection to Post Management/ Inspection in Private Sectors-Disposal Safety, Participation from Local Communities & Enviornmental Organizations, Monitoring/ Multi-Barriers-Triple Barriers-Disposal,Container, Silo, Natural Rock

Level of Radiation at the Disposal Facility

Annual radiation limit for an ordinary person:
1 mCV (millisievert) per year (not including 2.4 mCV of the natural radiation)

Actual level of radiation at the disposal facility:
0.004 mCV per year (It is less than 0.01 mCV, the level of radiation exposure from watching TV for 1 year)

Disposal Method

Underground Silo

Safety of Underground Silo Disposal Facility


Silo disposal is a method using natural and artificial barriers in a rock cavern in bedrock or under the ground, and the safety can be ensured by artificially excavating a silo.

Near Surface Disposal

Safety of Near Surface Disposal Facilities Reinforced with Artificial Barriers


Near surface disposal is a radioactive waste disposal method with a natural or artificial barrier in depth of about 30 m underground, and disposal with an artificial barrier is widely used to secure safety.

Transportation System

Hanjin Cheongjeong Nuri

Hanjin Cheongjeong Nuri, a radioactive waste transport ship, was built to safely transport radioactive wastes generated from each nuclear power plant and nuclear-related facilities to the disposal facility.

Features

Length and Width: 78.60m / frasl: 15.80m

Draft: 4.0 m

Total Tonnage: 2600 tons

Total Deadweight Capacity(DWT): 1365tons

Speed: 12.0 Knots

Engine: Double Diesel Engine Units (1632 HP each)

Max. Capacity: 190 Containers (1,520 Drums)

Characteristics of Hanjin Cheongjeong Nuri

It is designed and built with double-hull and double engine structure to prevent leakage in case of an accident.

An accident is prevented by state-of-the-art electronic equipment such as Automatic Identification System (AIS) and Automatic Radar Plotting Aids (ARPA). - The radiation level in the ship is automatically monitored by radiation monitoring system.

The radiation level in the ship is automatically monitored by radiation monitoring system.

Radiation protection and emergency response plans are established to prepare for an unexpected accident.

Safety is further guaranteed by prominent sailing personnel and radiation safety officers on board.
