(If mare space is required use asditinal copies of SUMMARY OF THE EVENT, INCLUDING DATES AND APPROXIMATE TIMES The CPSES Control Room is common to both Units 1 and 2. There are two 50 percent capacity air conditioning units that make up a single Train of the Control Room Air Conditioning System [EIIS:(VI)]. All four Control Room Air Conditioning System (CRACS) units share common ductwork. CRACS units X-01 and X-02 comprise Train A and CRACS units X-03 and X-04 comprise Train B. Normal alignment for CRACS support systems is as follows:
Train A CRACS Unit and Supporting SSCs:
Unit 1 Train A CRACS unit X-01 Unit 1 Train A Diesel Generator Unit 1 Train A Component Cooling Water Unit 2 Train A CRACS unit X-02 Unit 2 Train A Diesel Generator Unit 2 Train A Component Cooling Water (If we spae is requd use addtonal copes of (If more space is required use akidgtnnailcopies of (If more space is requred. use idtinonal copies of (If nore space requred. use aditional copts of (If more space Is required, use addiLional copies of (If tnre space is requedw we additional copies of (if nore spaec is required use additional copies of NRC Form 366A) (17)
