 Hi, I'm Henry Jones. I'm a hydrologist. I work for the Office of New Reactors in the Division of Site and Environmental Analysis in the branch of hydrology and meteorology. Hydrologist is a scientist that studies water, its distribution, and its impact on the environment and our impact on water. Well, we both serve in two roles, one in the safety side and also the environmental side. In the safety side, we look at how water will impact our safety structures. What I mean, for example, storm surge and tsunami and local precipitation, will they flood the plant? Will they scour and dig up power lines or piping? Will the buildings be watertight from leakage? On the environmental impact side, we might look at how, if there's an accident, will the radionuclides travel in the water to a nearby place, farms or plants, where people may ingest the radiation. So, we play both sides that are very integral to each other. Well, we're critical in that most of your sites depend on water to determine if they have the proper siting. If a site cannot have enough water or enough water for an emergency, they can either put the site there or neither would it be licensed to put a plant there without the water. So, hydrologists play a critical role in that. We'll look at the applicant's review and see if they could put their safety structures to be safe from tsunami, surge, dam break, river flow, local precipitation and on the environmental side that if there's an accident that nothing would impact the public safety.
