For the purposes of the present chapter and following the discussion in section 6.3, the sums of the O&M and fuel costs for land-based SMRs were taken equal to the corresponding sums for NPPs with the reference large reactors. For barge-mounted plants, the corresponding sums were multiplied by a factor of 1.5 reflecting the assumption of a higher O&M costs owing to the need of periodical factory repairs of a barge[56], see the discussion in Section 6.3. The resulting O&M and fuel costs (components of the LUEC) for SMRs plant configurations considered are given in Appendix 3 (Table A3.6).

4*335 MWe (USA) 5*125 MWe (USA) 2*300 MWe (Russia) 2*300 MWe, barge (Russia) 1 *90 MWe (Korea) 2*35 MWe, barge (Russia) 2*8 MWe, barge (Russia)
