The safety analyses and evaluation works on the process and facility for ACP demonstration have been performed. The several safety factors, such as the risk, environmental, radiation, structural, criticality, were analyzed. The analysis results confirmed the reliability of the safety on the ACP process and facility during normal and accident conditions.

KAERI (Korea Atomic Energy Research Institute) has developed the GAMMA+ code for a thermo-fluid and safety analysis of a VHTR (Very High Temperature Gas-Cooled Reactor). A key safety issue of the VHTR design is to demonstrate its inherent safety features for an automatic reactor power trip and power stabilization during an anticipated transient without scram (ATWS) accident such as a loss of forced cooling by a trip of the helium circulator (LOFC) or a reactivity insertion by a control rod withdrawal (CRW). This paper intends to show the ATWS assessment capability of the GAMMA+ code which can simulate the reactor power response by solving the point-kinetic equations with six-group delayed neutrons, by considering the reactivity changes due to the effects of a core temperature variation, xenon transients, and reactivity insertions. The present benchmark calculations are performed by using the safety demonstration experiments of the 10 MW high temperature gas cooled-test module (HTR-10) in China. The calculation results of the power response transients and the solid core temperature behavior are compared with the experimental data of a LOFC ATWS test and two CRW ATWS tests by using a 1mk-control rod and a 5mk-control rod, respectively. The GAMMA+ code predicts the power response transients very well for the LOFC and CRW ATWS tests in HTR-10.

For the safety assessment of the demonstration-scale incineration plant for treating the combustible radioactive wastes, radiation doses of a worker and a residential individual were estimated. The demonstration plant showed a good performance of trial-burn tests using non-radioactive tracers with resulting In high mass reduction of around 40 times and very low emmission of dusts through a stack, which promised a high decontamination factor in an order of 10$^{7}$ . Based on the result s obtained from the trial-burns in the process, the estimation of radiation dose for workers and general publics near the plant was made using dose pathway calculation theories. The parametric values for calculation were selected from design and operational results of the process and from more conservative conditions In reference data. The estimated annual doses for workers and residential indivisuals were 3.07 $\times$ 10$^{-4}$ and 4.35 X 10$^{-8}$ $\mu$Sv/y, respectively, which were high enough to operate the process when comparing with the allowable dose limit in the regulation. The dose calculation models were quite applicable with showing an excellent safety for the process.

Performance demonstration with real flawed specimens has been strongly required for nondestructive evaluation of safety class components in nuclear power plant. Specimen has been designed to produce mechanical fatigue flaw with tension stress and fatigue flaw has been produced to control stress and cycle, for suitable roughness. Notch condition is considered for control of fracture mode. After seal welding for fracture surface, final welding was performed to complete flaw specimen with GTAW(Gas Tungsten Arc welding) and FCAW(Flux Cored Arc Welding). It was demonstrated flaw size of flawed specimen by radiographic. testing and ultrasonic testing.

본 연구는 2010년과 2015년 전국 16개 지역에서 발생한 집회시위 현황을 연구대상으로 선정하고 집회시위 발생현황에 대한 지역별 군집을 분석하여 그 변화를 알아보는데 그 목적이 있다. 이에 따른 연구결과는 다음과 같다. 첫째, 2010년 집회시위 발생현황에 대한 지역별 군집은 1단계로 (1) 광주, 충남, 인천, 충북, 경북, 대구, 강원, 제주, 대전, (2) 전남, 경남, 부산, 전북, 울산, 경기, (3) 서울 등 3군집으로 구분되고, 2단계로 (1) 광주, 충남, 인천, 충북, 경북, 대구, 강원, 제주, 대전, 전남, 경남, 부산, 전북, 울산, 경기, (2) 서울 등 2군집으로 구분된다. 둘째, 2015년 집회시위 발생현황에 대한 지역별 군집은 1단계로 (1) 울산, 강원, 충북, 충남, 인천, 경북, 전남, 광주, 제주, 대구, 대전, (2) 부산, 전북, 경남, (3) 서울, 경기 등 3군집으로 구분되고, 2단계로 (1) 울산, 강원, 충북, 충남, 인천, 경북, 전남, 광주, 제주, 대구, 대전, 부산, 전북, 경남, (2) 서울, 경기 등 2군집으로 구분된다. 셋째, 집회시위 발생현황에 대한 지역별 군집 변화는 2010년 '전남, 경남, 부산, 전북, 울산, 경기'는 '집회시위 관리지역(사회 문화, 노정, 경제 중심)', '서울'은 '집회시위 빈발지역'으로 구분되고, 2015년 '부산, 전북, 경남'은 '집회시위 관리지역(노정 중심)'으로, '서울, 경기'는 '집회시위 빈발지역'으로 구분된다. 이는 집회시위 관련 치안정책이 지역별 집회시위 증감 정도, 지역별 집회시위 군집 변화 등을 고려하여 가변적으로 수립, 시행될 수 있다는 것을 시사한다. 나아가 '인권을 지향하는 경찰'을 토대로 하는 효율적인 집회시위 관리에 도움이 될 수 있다.
