Applicable codes and standards are provided in Table t'u$:n 9.1-21. gpB hLdko 9.1.2.2 Facility Description l 9.1.2.2.1 General Description The spent fuel storage facility consists of the spent fuel pool, containing anodized aluminum spent fuel storage racks, and serves as the storage area for irradiated fuel assemblies. The spent fuel pool and the adjacent reactor well, dryer / separator pool, l and cask loading pit are located in the refueling area as shown in Figure 1.2-14. Figure 9.1-34 shows the arrangement of the spent fuel storage racks. Cooling and cleanup of the spent fuel pool water is discussed in Section 9.1.3. Fuel handling systems are discussed in Section 9.1.4. The reactor enclosure crane is discussed in Section 9.1.5. 9.1.2.2.2 Component Description Spent Fuel Pool - The spent fuel pool is a post-tensioned, reinforced concrete structure that forms an integral part of the reactor enclosure. The pool has a volume of approximately (* 46,000 ft* and is filled with demineralized water to a normal depth of 38 feet, 3 inches. This provides about 23 feet of water above the tops of the stored fuel assemblies. The spent fuel pool is lined with stainless steel plate to minimize leakage and reduce corrosion product formation. A leakage collection system is provided to permit. expedient detection of leaks through the stainless steel liner plate and to prevent the uncontrolled loss of pool water to areas below the i pool. Drainage paths, designed to permit free gravity flow, are formed by welding channels behind the pool wall liner welded r MO joints and by two trench monitoring systems embedded in the floor slab below the floor liner. The design of Ste" typical draina OfW system is shown in Figure 9.1-40. Fool leakage is routed t ough a piping system, provided at the base of the pool wall to Wee dirty radwaste f unnels as shown in Figure 9.1-3. f,edayc,. b eack d 1, se w Es Leakage is detected by observation of water flowing out of the y piping into the dirty radwaste f unnels (Figure 9.1-3) or by low gg-level indication in the skimmer surge tank or the spent fuel pool (Figure 9.1-3). The leakage t a i.e is limii.ed by t40 ' inch linet -,/4 ;S I drain linx, leaks _can-be-nsuaHy rdent+f+ed and--isolated-by ]t slonng-the-manua L isolat-isa valves as - reger-eds 8 Control rod storage hangers in the spent fuel pool provide storage capacity for 76 control rods. g }& Nasido % b e,b. 6 S o Rev. 16, 01/83 g p L. a :.s.; w t w L g%. gf m
