Over the years, probabilistic risk assessment (PRA) research activities conducted at the U.S. Nuclear Regulatory Commission (NRC) have played an essential role in support of the agency's move towards risk-informed regulation. These research activities have provided the technical basis for NRC's regulatory activities in key areas; provided PRA methods, tools, and data enabling the agency to meet future challenges; supported the implementation of NRC's 1995 PRA Policy Statement by assessing key sources of risk; and supported the development of necessary technical and human resources supporting NRC's risk-informed activities. PRA research aimed at improving the NRC's understanding of risk can positively affect the agency's regulatory activities, as evidenced by three case studies involving research on fire PRA, human reliability analysis (HRA), and pressurized thermal shock (PTS) PRA. These case studies also show that such research can take a considerable amount of time, and that the incorporation of research results into regulatory practice can take even longer. The need for sustained effort and appropriate lead time is an important consideration in the development of a PRA research program aimed at helping the agency address key sources of risk for current and potential future facilities.

To evaluate the antioxidant and antitumor potential of a newly bred rice, Hiami (Suweon-511), total polyphenol content, $\gamma$-oryzanol content, radical scavenging activities, and antitumor activities were measured (control: Ilpum). Total polyphenol contents were 6.31 and 3.75 mg/g for unhulled (UHR) and hulled rice (HR) of Hiami, which was higher than that of Ilpum (5.66 and 3.47 mg/g). The $\gamma$-oryzanol contents were 33.53 and 39.47 mg/100 g for UHR and HR of Hiami, which was higher than that of Ilpum (24.33 and 28.68 mg/100 g). DPPH radical, hydrogen peroxide, superoxide radical and hydroxyl radical scavenging activities of 70% ethanol extracts of Hiami were higher compared to Ilpum, and UHR was higher than those of HR. Antitumor activities of the 70% ethanol extracts of Hiami and Ilpum were increased with a dose-dependent manner. The extracts of Hiami have higher activities of antitumor activities on gastric and breast cancer cell lines compared to other cancer cell lines, and Ilpum has higher activities of antitumor activities on colon and liver cancer cell lines.

Allium hookeri (Liliaceae), native to India is widely cultivated in Korea lately as a medicinal plant. This study was performed to evaluate the antioxidant and lifespan extending effects of the root of A. hookeri. Methanol extract from the root of A. hookeri was successively partitioned as methylene chloride, ethyl acetate, n-butanol and H₂O soluble fractions. Antioxidant effects of the fractions were measured by measuring the radical scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH), and superoxide quenching activities. Lifespan extending effects of the fractions were investigated using Caenorhabditis elegans model system. In addition, stress resistant, superoxide dismutase (SOD) and catalase activities, and intracellular reactive oxygen species (ROS) levels were also studied. Furthermore, we had investigated aging-related factors such as reproduction, food intake, growth and movement of C. elegans to find any sample-induced significant change. Our results revealed that ethyl acetate soluble fraction from the root of A. hookeri showed the most potent antioxidant and lifespan extending effects, and this fraction elevated the most potent SOD and catalase activities of worms, and reduce intracellular ROS accumulation.
