X-300A PROCESS MONITORING BUILDING (COMPUTER BUILDING)

Facility Information

The X-300A Process Monitoring Building was built by the Peter Kiewit Sons’ Construction Company in 1954 and is currently in use by the Radiation Protection group as an Emergency Response Room (ERR). The ERR contains the equipment, supplies and resources for the Radiation Protection personnel to use when responding to emergencies. In addition, the shift Radiation Protection personnel maintain their work stations there and keep the ERR inventory. The X-300A is located just west of the circulardomed X-300 building.

Formerly known as the “Computer Building,” the X-300A Process Monitoring Building originally held the electronic monitoring equipment that tracked plant processing, including the central processing unit for the cascade automatic data processing system (CADP). The CADP System was utilized prior to the shutdown of the Cascade and is no longer in service. The central processing unit (CPU) has been removed.

The building has a poured concrete slab foundation, reinforced concrete walls, no window openings, and a relatively flat roof. There is an L-shaped concrete block addition on the west half of the southern façade. The main building has one entry located on the north façade with a heavy solid metal blast door. The addition has two metal entry doors on the west façade and one inset in the south façade. The main building has 1,430 square feet of floor space.

The interior of the building previously housed a variety of computers and equipment used in the monitoring of plant processing systems. Floors in the building are covered with linoleum, with certain panels perforated to allow for increased air flow to keep the computer equipment cool. The walls are clad in a fibrous wallboard material, and the building has a drop ceiling with acoustic tiles and inset troffer-type fluorescent lighting.
