On November 4th, 2015, the seminar for freshman class went on a trip to visit the Nuclear reactor of MIT. After arriving there there, we all had to leave our bags in a room because we can’t bring anything to the nuclear reactor. But before going to the nuclear reactor, an Assistant Superintendant, Frank Warmsley the III, gave us a lecture about the nuclear reactor history. Like, the reactor was opened in 1958, and it upgraded two times, one in 1975, and later in 2010. Right now, it operates at a high 6 MW thermal power, and that is produces no greenhouse gases. Also it uses water as a coolant.There was stuff I didn’t get, but he said some interesting things that I haven’t heard about before. After we finished from the lecture, we will finally went to the reactor itself. The hype was real. I have not been to a nuclear reactor before in my life, so this was so exciting for me, and pretty much all of us. Before we gone to the reactor, the door to enter it was an air lock, and it uses an iris scanner lock. I didn’t know it existed until that day. There was another thing that I didn’t expect was the reactor is in fact blue colored. Unlike cartoons and other tv series that say the reactor is green.Finally, we went to the control room, where everything is controlled there. There, a guy who works to keep an eye out for if anything happens, but it is rarely that something major happens because this nuclear reactor is for research purposes only. When we finally were about to finish for today, we had to scan our bodies with this machine that would detect if we picked up any nuclear particles along our tour. Going to this trip was worth it, and would definitely go again if I had the chance.
