Introduction

During and after World War 2, The United states of America was developing nuclear weapons in large quantities. They wanted to develop a secret industrial facility to manufacture nuclear weapons. In June 1942, the Manhattan Engineer District of Army Corps of Engineers (MEDACE) was inculcated to locate a site where the desired facility could be developed. In March 1943, a site in southern Washington State was developed as a plutonium production site with an area of approximately 560 square…
