Cooling Water System CWS

This section evaluates the structuraT integrity of the pressure boundaries of the PWS, the Engineered Safety Feature (ESF) Systems, and the Cooling Water System (CWS). Evaluation of the ESF system structural integrity includes the following safety systems ... 

DB 2.7 - Seismically Qualified Cooling Water System (CWS) -- Ensure that the shutdown cooling functions of the cooling water system is seismically qualified by analyses, and by DOE approved walkdowns etc. Seismic issues are described in Section 6.1 of this report.

These substances are used on site for water treatment further details regarding use of these substances are provided in UKP-GW-GL-035 (Reference 14.23). These substances are stored in liquid/solution form in tanks located within the turbine building (Table 6.4.1 of the EDCD, Reference 14.2). Tank locations within the building will be subject to detailed design/layout. These substances are used primarily in association with the cooling water system and are stored in the circulating water system (CWS) area, in an area reserved for chemical storage. 

One feasible network would correspond to the cold streams Cl, C8, and C9 diverted to suitable jacketed reactor compartments, as the simple network in Fig. 14 shows. The hot streams not shown in this network are matched directly with cooling water (CW), and the amount of steam used here is very small. Note that this network would require the same minimum utility consumption predicted by the solution of (PIO). It can be inferred that the network in Fig. 14 is equally suitable for both the simultaneous and sequential solutions. In fact, Balakrishna and Biegler (1993) showed that, for exothermic systems in which the reactor temperature is the highest process temperature, the pinch point is known a priori as the highest reactor temperature (in this case, the feed temperature) and the inequality constraints in (PIO), Qh 2h () ). F G P. can be replaced by a simple energy balance constraint. This greatly reduces the computational effort to solve (PIO).

The normal source of makeup water to the K-, L-, and P-Reactor Disassembly Badns is from the filtered water system throu two makeup water fines. One of the fines supplies the MB, while the other supplies the VTS badn (Ref 8-28). Inhered water to eadi badn is supplied through a manual blodc valve and then to a pneumatically operated butterfty valve. The water then flows into the respective section of the Disassembly Bam Filter water can be automatically controlled, but is not usually operated in this manner. Makeiq> water addition is normally manually controlled via the manual block valves. The emergency cooling water pump suction header CW-39 and the river water header RW-1 were once alternative sources of mak water to these Disassmbly Basins. Each of these alternate sources of water have been drained and isolated from the Disassembly Basins (Ref 8-27), and are not considered as sources. 

One of our major goals was to make this technology work with room-temperature GaAs lasers. These are small, efficient, can be current modulated, are potentially inexpensive and reliable but have limited power. At present, 10 to 20 mW CW is the most one can expect to achieve reliably. In comparison Nd YAG lasers are bulky, expensive, inefficient, require water cooling and the pump-lamps have limited lifetime. In addition, an expensive modulator (e.g., acousto-optic) is needed for the LV system.
