Ms. Christina Prah (NPP second-year)’s paper was selected as a best paper of KARP (Korean Association for Radiation Protection) Fall conference 2022.

The Introduction of the paper is:
  A nuclear accident is any operational deviation of a nuclear reactor from the normal that leads to the destruction of a reactor and containment shielding integrity and subsequent radiation release to the environment. Despite prior safety incidents, nuclear power has a long history of supplying the cheapest and enough electrical supply needed for expanding businesses. Nevertheless, the widespread use and commercialization of nuclear power plants in underdeveloped nations are hindered by the safety issues of every first-of-a-kind (FOAK) technology. Notably, public and regulatory distrust surrounding the nuclear industry's safety and security is increased by terrible historical occurrences, such as the TMI, Chernobyl, and Fukushima Therefore, every risk-related operation must, by definition, have emergency planning and preparedness to safeguard the public and the environment. Therefore, the IAEA proposes addressing nineteen (19) critical concerns before any nuclear facility is established, including emergency preparation. The Emergency Planning Zone (EPZ), in the vicinity of the nuclear power plant, is where additional considerations and management strategies are planned and put into reality in the event of a nuclear emergency. The EPZ is divided into the plume exposure pathway (up to 16km) and the ingestion exposure pathway (extends about 50 to 80km). Within the plume exposure pathway is the exclusion area boundary (EAB) set between 800m to 6000m, and a low population zone found behind the EAB with a population density of fewer than 25000 people. Additionally, the NRC Regulatory Guide 1.195 and 10 CFR 100 states that anyone within the exclusion area border (EAB) should not receive a thyroid dose above 3000mSv and a whole-body dose estimate greater than 250 mSv for two hours after the onset of a severe event. For a person residing within 30 days of the progression of the accident, the preceding requirements are the same for the low-population zone.
Control room habitability systems enable control room staff to maintain their safety while minimizing the effects of radioactive releases through safe plant operations in the event of accidents. To ensure habitability within 72 hours of accident progression, control room doses must not exceed 50 mSv according to the Code of Federal Regulations 10 CFR 50.34. 

This project seeks to evaluate the maximum doses at the emergency planning zone and control room for APR1400, VVER1200, HPR1000, and Nuscale Power Module. It does this by adopting the SNAP/RADTRAD codes to simulate REA and   FHA. The REA and FHA simulation output will estimate the doses at the EAB, LPZ, and control room. The four reactors understudy are pressurized, and light water reactors incorporated passive safety features.

Mr. Lee Joo-ho (EPE second-year)’s paper was selected as a best paper of KARP (Korean Association for Radiation Protection) Fall conference 2022.

The Introduction of the paper is:
   The release of radioactive materials during nuclear accident has a serious impact on the environment and human health. Therefore, it is necessary to conduct a radiological consequences analysis to analyze the accident situation and take prompt protective actions during accident. In the 2011 Fukushima accident, it was difficult to estimate the amount and effect of radioactive materials using internal information and environmental monitoring due to the earthquake and tsunami. So, the estimation of source term using environmental monitoring was recommended. Therefore, we propose a new source term estimation strategy that overcomes the existing physical limitations and errors of estimation. In this study, a feasibility study on the estimation of source term using the environmental monitoring based on UAV and Deep Learning technology is proposed and conducted.

The 12th colloquium was held in the KINGS auditorium with approximately 80 people of the KINGS community on 22 November 2022. The invited speaker, Dr. Hwang Yong-soo, President of KINAC, delivered a lecture titled DPRK Nuclear Issues - DPRK Nuclear Capability and Our Responses.

After the lecture, Dr. Hwang and audience of KINGS students and KINGS professors had a Q&A session on how to stop North Korea to develop nuclear weapon and North Korea’s electricity grid.
