It is shown that on creation of capital reserve to cover the risk of hypothetical severe accidents in NPP the size of the allocation is comparable to or greater than the fuel costs for a power-generating unit of a large NPP. The damage consequent to severe accidents in NPP is 1000 times greater than the insurance limits adopted for nuclear risks. An empirical power-law function (with exponent 1.6) representing the damage consequent to a severe accident as a function of the reactor capacity is studied. As a consequence of the nonlinearity of the reduction of the scale of the damage caused by a hypothetical accident on transitioning to small modular reactors (SMRs) the capital reserve allocated for risk insurance for NPP becomes realistic.

结果表明，在建立资本准备金以覆盖核电厂假设的严重事故风险时，拨款规模可与大型核电厂的发电装置的燃料成本相当或更大。NPP严重事故造成的损失比核风险所采用的保险限额大1000倍。研究了经验功率定律函数（指数为1.6），该函数代表了严重事故导致的破坏，该函数是反应堆容量的函数。由于在过渡到小型模块化反应堆（SMR）时发生的假设性事故造成的损害规模减少的非线性影响，分配给NPP的风险保险的资本准备金变得现实。
