Master ThesisFrancesco Paolo Caravello
1) Safety Analysis in the Cooling System of the SPES Target/Source: analysis and variation with respect to EXCYT (LNS).
1) Top Event: GROWING of the Temperature of the Cooling Fluidover the imposed limit (19oC)
Frequency of happening of the TE
P(TE) = 5.3*10-3 year-1
(accidental event every 200 years)
2)Top Event: Evaluation of the majorEnvironmental Impact after dispersion ofactivated material (from the target) afterirradiation.
2) Safety Analysis : Evaluation of the production of the Radio-isotopes and theirchains after irradiation of UCx target
