Nuclear power plants in Korea stores approximately 3,800 drums of paraffin solidification products. Due to the lack of homogeneity, these solidification products are not allowed to be disposed of. There is therefore a need for the separation of paraffin from the solidification products. This work developed an equipment for a selective separation of paraffin from the solidification product using the vacuum evaporation and condensational recovery method in a closed system. The equipment mainly consists of a vacuum evaporator and a condensational deposition recovery chamber. Nonisothermal vacuum TGAs, kinetic analyses and kinetic predictions were conducted to set appropriate operation conditions. Its basic operability under the established conditions was first confirmed using pure paraffin solid. Simulated paraffin solidification product fixing dried boric acid waste including nonradioactive Co and Cs were then fabricated and tested for the capability of selective separation of paraffin from the simulated waste. Paraffin was selectively separated without entertainment of Co and Cs. It was confirmed that the developed equipment could separate and recover paraffin in the form of nonradioactive waste.

Improvisation is an important firm competence in product innovation as firms increasingly face inherent uncertainty in new product development (NPD) process and frequent jolts in the external environment. While there is some empirical and conceptual work on the value of improvisation for several new product outcomes, there is lack of empirical research on the antecedents of improvisation in innovation studies. We attempt to address this gap by studying the role of team variation and team convergence traits in the occurrence of improvisation in a sample of 118 NPD teams from manufacturing firms.

The purpose of this paper is to understand how customer relationship termination (i.e., preparation and process), alone or in combination with customer involvement, contributes to the new product development outcome. While termination preparation has a synergistic effect with customer involvement, the termination process has a trade-off relationship with customer involvement.

Molten Salt Reactor (MSR) is one of Generation-IV nuclear reactors that uses molten salts as a fuel and coolant in liquid forms at high temperatures. The advantages of MSR, such as safety, economic feasibility, and scalability, are attributed from the fact that the molten salt fuel in a liquid state is chemically stable and has excellent thermo-physical properties. MSR combines the fuel and coolant by dissolving the actinides (U, Th, TRU, etc.) in the molten salt coolant, eliminating the possibility of a core meltdown accident due to loss of coolant (LOCA). Even if the molten salt fuel leaks, the radioactive fission products dissolved in the molten salt will solidify with the fuel salt at room temperature, preventing potential leakage to the outside. MSR was first demonstrated at ORNL starting with the Aircraft Reactor Experiment (ARE) in 1954 and was extended to the 7.4 MWth MSRE developed in 1964 and operated for 5 years. Recently, various start-ups, including TerraPower, Terrestrial Energy, Moltex Energy, and Seaborg, have been conducting research and development on various types of MSR, particularly focusing on its inherent safety and simplicity. While in the past, fluoride-based molten salt fuels were used for thermal neutron reactors, recently, a chlorine-based molten salt fuel with a relatively high solubility for actinides and advantageous for the transmutation of spent nuclear fuel and online reprocessing has been developing for fast neutron spectrum MSRs. This paper describes the development status of the process and equipment for producing highpurity UCl3, a fuel material for the chlorine-based molten salt fuel, and the development status of the gas fission product capturing technologies to remove the gaseous fission products generated during MSR operation. In addition, the results of the corrosion property evaluation of structural materials using a natural circulation molten salt loop will also be included.

Molten Salt Reactor (MSR) is one of the generation-IV advanced nuclear reactors in which hightemperature molten salt mixture is used as the primary coolant, or even the fuel itself unlike most nuclear reactors that adopt solid fuels. The MSR has received a great attention because of its excellent thermal efficiency, high power density, and structural simplicity. In particular, since the MSR uses molten salts with boiling points higher than the exit temperature of the reactor core, there is no severe accident such as a core melt-down which leads to a hydrogen explosion. In addition, it is possible to remove the residual heat through a completely passive way and when the fuel salt leaks to the outside, it solidifies at room-temperature without releasing radioactive fission products such as cesium, which make the MSR inherently safe. Both fluoride and chloride mixtures can be used as liquid fuel salts by adding actinide halides for MSRs. However, the MSRs using chloride-based salt fuels can be operated for a long time without adding nuclear fuel or online reprocessing because the actinide solubility in chloride salts is about six times higher than that in fluoride salts. Therefore, the chloride-based MSRs are more effective for the transmutation of long-lived radionuclides such as transuranic elements than the fluoride-based MSRs, which is beneficial to resolve the high radioactive spent nuclear fuel generated from light water reactors (LWRs). This paper examines liquid fuel fabrication using an improved U chlorination process for the chloride-based MSRs and presents the strategy for the management of gaseous fission products generated during the operation of MSR.

포스트바이오틱스(postbiotics)는 프로바이오틱스(probiotics)가 발효과정 중 생산하는 유용한 대사산물과 미생물의 구성성분을 포 함하는 개념이다. 포스트바이오틱스는 기존 프로바이오틱스 소재가 갖는 안전성(safety), 기능성(function), 안정성(stability)의 한계를 극복할 수 있는 새로운 대안 소재로 주목받고 있다. 사균화 처리과정으로, 특정 대사물질의 복합물 형태로 제조되고 있기에 기존 생균제보다 가공, 포장, 유통, 섭취가 용이하다. 면역력이 낮은 환자나 건강 취약 계층의 소비자들도 안전하게 섭취할 수 있는 것도 장점이다. 뿐만 아니라, 체내에서 면역 조절, 감염 방지, 지질 및 콜레스테롤 대사, 항산화 기능을 보이고 있어, 앞으로 건강기능 식품 우수 소재로 활용될 가능성은 더 커질 것이다. 다만, 대부분의 연구들이 아직은 세포실험과 동물시험인 단계이기에 실제 인체적용 시험을 마친 소재들은 적은 편이다. 향후 꾸준한 연구성과를 바탕으로 다양한 기능을 가진 포스트바이오틱스 소재와 제품들이 개발된다면 건강기능식품 산업에 새로운 성장동력이 될 것으로 예상 된다.

The nature of NPD is conducive to SMEs improvising at all stages of the process. This has the potential to create new knowledge, which, if retained and harnessed, can then be applied at higher strategic levels within the firm. This paper examines this phenomenon, through a preliminary qualitative study.

The concept of co-creation with consumers has been extensively studied in the literature documented in innovation management and marketing literatures. In this study, we contribute to the literature threefold. First, we develop a model to investigate how co-creation with fans enhance purchase intent and engagement of other customers. Second, we test the model using the data collected from consumers on four different product categories including beer, car, cosmetics and travel. By doing so, we examine the differences between product vs. service as well as different product categories. Third, we will compare the results with that of ordinary consumers to check if there are any differences in the case of co-creating with fans. Most of the extant studies have found a positive effect of co-creation on the outcome evaluation. However, engaging other consumers by co-creation with fans has not been studied. For bridging this research gap, we developed a conceptual model to investigate the antecedents and consequences of co-creation with fans. The hypotheses are as follows. H1: Product class involvement and domain specific knowledge affect perception on co-creation positively. H2: Perception on co-creation affects purchase intent and word-of-mouth positively. H3: The relationships of H1 and H2 differs depending on product categories. H4: The relationships of H1 and H2 differs if companies work with ordinary customers or fans. We tested the hypotheses with the data collected from consumers an online questionnaire survey. Data collection was conducted through a market research agency in 2016 for beer and cars, and in 2019 for cosmetics and travel. The data was collected from 240 consumers in their 20s, 30s, and 40s in Japan. Each segment has same number of males and females, 40 people each for six segments. The findings shed a new light on the co-creation literature and help companies to design better co-creation with fans in different product and service categories.
