亚临界试验区的概况美国迄今为止的13次亚临界实验,都是在美国内华达核试验场亚临界试验区的地下实施的。亚临界试验区在内华达核试验场中部的1号试验场区内,总面积约1.2平方千米,中心坐标为北纬37°00′262″、西经116°03′26″。该地区海拔1200米,地表为典型的沙漠地貌,地下为厚度约600~700米的第四纪冲击岩,岩石硬度低,地下水流速缓慢,水位
OVERVIEW OF THE SUBCRITICAL CRITIC EXPERIMENTAL AREAS Thirteen sub-critical experiments in the United States so far are conducted underground at the subcritical pilot zone of the United States nuclear test site at Nevada. The subcritical test zone covers a total area of about 1.2 km 2 in the No. 1 experimental zone in the central part of the Nevada Nuclear Test Site with coordinates of 37 ° 00’262 "north latitude and 116 ° 03’26 west longitude. The area is 1,200 meters above sea level, the surface is typical of the desert landscape, the ground is about 600 ~ 700 meters thick quaternary rock, rock hardness is low, the groundwater flow is slow, the water level
