CTL020184 Page 3 GENERAL CONSIDERATIONS. Reactor venting Ulhat level of initiator overcharge should be allowed for in designing the reactor safety venting system? Please check one. No Overcharge allowed for X Overcharge allowed for is _____ % Reaction rate not taken into account in design ____ CoMMents ___________ ___________________________ Bulk initiator delivery Do you feel that bulk initiator (i) feasible? (yes/no) <2) Desireable? (yes/no) delivery No Yes and handling is Comments T7e only use C75 solution 75 percent because of overrating and econoruc considerations. INITIATOR TYPES Several forms of peroxydicarbonate or perester initiator are now offered, you are asked tu rate these in terns of suitability for plant operation. PHYSICAL FORM RATINGS <i) QV. 3AF OP. EC. A. Pure solid (at ambient temperature) ______ _____ _____ _____ B. Pure liquid _____ _____ _____ ______ C/7S Solution (75%) _____ _____ _____ _____ D/40 Frozen water emulsion of liquid <40%) _____ _____ _____ _____ E/SO Emulsion of liquid with antifreeze (60%) ______ _____ _____ _____ F/40 Water dispersion of solid (40%) _____ _____ _____ _____ C Other (specify - could be E/70 etc.) Notes (i) 00. = Overall rating* SAF = Safety considerations only. OP. = Operability* EC. = economic considerations. Indicate your opinion in the requisite space as follows A = Prefered B = Adequate or acceptable C = Inadequate- needs excessive precautions, gives excessive operating difficulties, or is prohibitively expensive. D = Do not have an opinion. E = Possible future choice - not yet developed, CTL020185 INITIATOR HAZARDS DUE TO INJECTION TO REACTOR IN CLOSED MODE.
