In the area of property insurance (corporate) there are times when certain industrial objects cannot be taken over by the insurance company if they cannot reinsure most of the risks that may cause damage to their objective. A significant example can be Cernavoda nuclear plant for which the insurance mechanism involves dispersion of risk as much as possible. Therefore it is secured by two pools (unions of insurance companies which associate to cover risk) with tradition in nuclear security: one is British, British Atomic Energy Insurance Comity (which includes 60 companies) and another Italian (which includes 30 companies). If to these figures we also add the ten participating Romanian insurance companies as well as the companies that are involved indirectly as reinsurers, we can easily draw the conclusion that the number of companies participating in one way or another to ensure the Cernavoda nuclear power plant is over 100.
