As you requested, Mr. Paulson and I have prepared a tentative sketch of the floor plan and external appearance, of a building specifically designed to house the Nuclear Reactor State College intends to build. The details are not completely thought out, but the four essential features at the eventual instal- lation (sketch 1, left above) are included. They are, in order of importance: 1. The Reactor Room, with the nuclear reactor, a huge octagonal block of concrete 17 feet across and 11 feet high (largely underground and partly below floor level), in the center of the room. Around the reactor must be space for experimental equipment. Opposite each opening in the concrete block, from which a collimated beam of radiation may emerge, a narrow opening in the building wall leading to an underground radiation trap, must be provided. Head room above the reactor is needed for large ventilation blowers, and for lifting crane. 2. The Research Wing, or more correctly, the pre-and post-exposure sample pre- paration, handling and counting laboratories. These facilities for specimen manipulation immediately adjacent to the Reactor Room will more than double the types and importance of research projects which can be undertaken. This wing must be equipped for the handling of highly radioactive materials. 3. The Student Wing. With the press of research problems certain to be scheduled for the Reactor, and the high level of radioactivity, it will be virtually impossible to have students in the Research Wing for nuclear technology training. Yet instruction and education is one of the fundamental objectives for which the Reactor is being established. Hence a space adjacent to the Reactor suitable for laboratory and student research activities is highly desirable. 4. The Control-Observation-Calculation-Records Area. If necessary, the control console can be located in one of the laboratory wings, adjacent to the Reactor Room. It is almost imperative however, that there be a sizable area near the Reactor which is completely free of radiations or radioactive materials. Cal- culations, records, observation facilities for visitors (of which there are certain to be many, because this will be the first reactor in the entire country--the world, perhaps, accessible to the public), etc. must be located outside "work" areas.
