Reactor service building

The machine shop is adjacent to the plug storage room so that the plughandling crane can be utilized by the shop. The shop provides for machine tool work, lead burning, welding, and sheet metal and pipe work. All these functions are designed specifically for exclusion-area work. 

The warehouse section is a two-floor area. The lower floor is designed for storage of heavy materials such as lead bricks or steel shielding plates. The space in general, is to store items needed for exclusion area work. Some office space is also available on this floor. The upper floor is designed for lighter storage and/or offices. 

The operations testing area is designed for the setup of mock up or functional test apparatus. A 10- by 50 by.10-ft-deep pit is located in one corner to allow for vertical apparatus height approaching 40 ft. Service outlets are provided in the pit and along the outer walls for the benefit of the experimenter. 

There will be a definite need for such a building on the site. Although it has not been constructed as a part of the initial program, it should be actively considered within the first year of operation.

Reactor Service Building (including Nuclear Island Cooling Water Building Chilled Water Building)... 

Response spectrum recorders are not supplied as discrete instruments. A permanently installed response spectrum analyzer provides more complete information than that provided by response spectrum recorders. Data from the strong motion accelerometers are fed into the response spectrum analyzer to produce earthquake spectra immediately following an earthquake. The response spectrtun analyzer is located in the Reactor Service Building with readout both there and in the Control Room. This system achieves the intent of Regulatory Guide 1.12, Revision 1. (Ref. 13)...

Sufficient space remains -for future additions to the Reactor Building wing, Process Water Building, Cooling Tower, Water Treatment Building, and Boiler House. Also, space is provided for future facilities such as an administration buiIding, reactor service building, cafeteria, and hot laboratory. 

A view of the general arrangement of the fuel-handling system is shown in Fig. 5.6. New fuel assemblies arrive at the plant in shielded and cushioned containers. They are unloaded and inspected in a shielded new fuel-handling facility located in the reactor service building (RSB). Upon acceptance of a core component, it is stored in a subcritical array in a storage facility located in the floor of the new fuelhandling facility. 

Ex-vessel transfer machine (EVTM). This rail-mounted transfer cask moves core component pots (CCPs) with fresh fuel and other core components from the EVST to the reactor vessel and moves CCPs with SNF and other core components from the reactor vessel to the EVST. The CCPs are small vessels used to transfer fuel and other components in a temperature-controlled sodium environment. The EVTM is also used for fresh fuel, SNF, and other transfer operations within the reactor service building and remains in the reactor service building during reactor operations. 

In the process of refueling, the EVTM first moves an empty sodium-filled CCP from the EVST into a transfer position on the periphery of the reactor core. The EVTM then returns to the reactor service building and removes a new fuel assembly in a sodium-filled CCP from the EVST while the IVTM in the reactor vessel removes an SNF assembly from the reactor core and deposits it into the empty CCP. The EVTM then places a CCP with a new fuel assembly in a second transfer position inside the reactor vessel and removes the sodium-filled CCP with the SNF assembly. The SNF assembly is transferred to the EVST. The cyclic process continues until refueling is completed. 

The EVST (Fig. B. 13) is a sodium-filled storage facility with a two-tier rotating turntable and a fixed closure head with fuel transfer ports. The EVST is located in the reactor service building between the EVTM gantry rails in a nitrogen-gas-filled concrete vault. The EVST performance characteristics are provided in Table B.3. Major EVST components and their primary functions are listed in Table B.4. 

Because of its small size, the reactor containment structure is located within a reactor service building. The general layout of systems and equipment within the reactor service building is as shown in Figures 1,2, and 3 with critical reactor auxiliary equipment placed near the reactor. Radwaste systems and equipment are situated at one end of the reactor service building away from the reactor. Large, heavy equipment is placed on the bottom floor elevation, while lighter equipment is located on the upper elevations. The system layouts are based on past experience with central station plants.
