하나로를 이용한 재료조사시험용 계장캡슐 개발에 앞서 캡슐 mock-up (96M-01K)을 제작하였으며, 이 캡슐 mock-up의 실제 하나로 조사시험공 장입시를 가정하여 강도 및 열적 건전성 평가를 수행하였다. 평가 결과 하나로 정상출력시 (30MW) 캡슐 mock-up 내 조사시료의 온도는 진공 및 heating system을 사용하여 279~473$^{\circ}C$ 범위로 조절될 수 있었으며, 목표 조사기간 동안 캡슐 mock-up은 강도적으로 허용기준을 충분히 만족함으로써 안전한 것으로 판명되었다. 향후 본 캡슐 mock-up을 이용한 노외 simulation 실험 등을 통하여 기존 캡슐 mock-up의 건전성을 확인한 후 이를 기준으로 하여 표준형 하나로 캡슐을 설계 .제작하고자 한다.

An experimental study was carried out with the Mock-up made for the improved water level control of the steam generator in nuclear power plant and for the confirmation of swell/shrink status of the water level by opening and closing the steam dump valve. We can confirmed the possibility of using the Mock-up by introducing the PI controller and the FUZZY controller. Accordingly, we can confirmed that the practical usability of advanced controllers, which will be developed for the improved water level control of the steam generator in nuclear power plant by using the Mock-up.

This study is analyze the damage of warehouse fire accident be made through the fire characteristic database of combustibles and real scale fire test of warehouse mock-up. Combustibles fire tests are carried out for database using RCT (Room Corner Tester) to predict fire growth the goods. A mockup ($3m{\times}3m{\times}2.4m$) of clothes warehouse was built and real scale fire test by LSC (Large Scale Calorimeter) base on the fire characteristic DB. The mock-up of clothes warehouse is made of two type sandwich panels (Glass wool, EPS foam sandwich panel). As a mock-up test result, test 1 (Glass wool sandwich panel) and test 2 (EPS foam sandwich panel) indicating fire growth such as 5 MW, 11 MW of maximum HRR (Heat Release Rate).

To minimize construction of nuclear facility, it is required to reduce reinforcing bar amount and solve reinforcing bar concentration and for this, it is necessary to develop appication design technology and modular of high strength reinforcing bar. Hence, KHNP reduces excessive reinforcing bar amount which can cause possibility of poor construction of concrete through design standard development and modular of nuclear facility structure using high strength reinforcing bar to raise economics and has its purpose to maintain high-level safety and durability as they are. After reviewing the rebar drawing of the NPP structures and performing the mock-up test, the rebar modulation method in the various area of the NPP Structure has been established.

Cable net system openness and flexibility is good high and the large deflection caused no damage to the structure itself. However, cable installation, install complex systems and technologies are needed. In this study, for the basic materials of cable net construction management, cable net expert's advice and mock-up test results are summarized.

This study aims to know temperature and humidity handling ability of Hwang-To brick and traditional paper window's in mock-up room test. To achieve these goals, mock-up room test was carried out. The results are as follows. 1) There are no significant differences among specimen in temperature handling capacity. 2) Traditional paper windows are very sensitive when compared with glass window in humidity control. 3) Traditional paper windows have a big handling capacity in humidity control when vapors letting out in mock-up room. 4) Hwang-To brick case is more stable than other cases in relative humidity variances because it has more potential to contain humidity.

In this study, experiments of development and application of 50 MPa high-performance concrete are performed for large dimensional tunnel linings. In order to produce 50MPa high-performance concrete, eight optimal mixtures replacing with fly ash and ground granulated blast furnace slag up to 50 percent of type I Portland cement were selected then tests for mechanical properties and simple adiabatic temperature rise tests were carried out. And in order to assess the quantitative characteristics of heat of hydrations of developed mixtures, three mixtures that the type I Portland cement (OPC) and each one mixture of binary and ternary mixtures (BS30, F15S35) were reselected, then the adiabatic temperature rise tests and mock-up tests were performed. Consequently, the comparisons between the results of mock-up tests and finite element analysis can be enhanced the reliability of analyzing routines of thermal behaviours of the developed high-performance concrete.

In this study, the failure and deformation characteristics of steel fiber reinforced shotcrete (SFRS) which is a primary tunnel support was investigated to find out ground-support mutual behavior. To this end, a mock-up of a tunnel was made and experimented with the conditions of lateral earth pressure coefficient 0.5 and 1.0. During the tests, 11 hydraulic cylinders were used for loading. for better simulation of the lateral earth pressure effect, these cylinders were controlled separately by two groups; crown and side wall. Meanwhile, the deformation of shotcrete was measured by 11 LVDTs. Backfill material was also used fur better load transfer from hydraulic cylinders to shotcrete. For the validation of the mock-up test results, 3D numerical analysis is carried out. To do numerical analysis under the same condition as a mock-up test, the load history curve which was obtained during the test was tried to be simulated using an individual FISH routine in the numerical analysis.

The ultimate objective of this research is to develop the technologies for the construction of 100-year housing as the first task for improving housing environments. The technological development of 100-year housing makes it possible to advance construction technologies and part development, to develop long-life housing with durability and Flexibility responding to customers' needs for future living space. At first, for this purpose, the applications according to the types of the Standard Model of Long-life Housing are proposed to respond to the life-cycle of near-future demographic and social structure, and the construction of the Mock-up House execute based on the location selected during the 2nd year and the basic plan. Then the Standard Model of Long-life Housing are advanced and proposed through evaluating the field applicability of the Mock-Up House.

Available daylight in inside offers comfortable view environment, and psychological and physical advantages to people in a room. Architectural design has a need for daylight prediction. But it is difficult to predict the illuminance values in daylight system. Using various Daylight simulation software is easy and simple, but we can find different results under the same conditions. This study compares with illuminance values from simulation (Lightscape 3.2, Relux 2007, Radiance 3.9) and Mock-up experiment with a same space and parameter of daylight (location of space and window, date, time and sky condition).
