FLOATING POWER GENERATING PLANT OF NUCLEAR POWER STATION OF SMALL CAPACITY
At the beginning of 90-ies Russian scientists suggested using floating nuclear stations to supply hard-to-reach area with heat and power. The most effective nuclear station of small capacity (ATES MM) on the basis of floating power generating plant reactor unit KLT-40S (reactors of such type have been successfully used on nuclear ice-breakers for more than 35 years).
By RF Ministry of Nuclear energy order (No.739 dd 30 November 2000), Severodvinsk (Arkhangelsk region) was chosen as the place for building main nuclear power plant of small capacity on the basis of floating power generating unit with reactor units KLT-40S. FSUE “PO “Sevmash” was appointed as general contractor.
By order of RF Ministry of natural resources (No.447 dd 18 July 2002) ATES MM National environmental impact assessment was approved.
By solution of RF Ministry of nuclear energy, FSUE “Concern “Rosenergoatom”, Russian shipbuilding agency technical project of floating power generating unit 20870 with reactor units KLT-40S for ATES MM was approved.
In RF Gosatomnadzor (Federal agency on ecological, technological and nuclear inspection) the following licensees were received:
- for building floating power generating unit on FSUE “PO “Sevmash”,
- for constructing ATES MM on the basis of floating power generating unit with reactor units KLT-40S in Severodvinsk,
- for designing and constructing floating means with reactor units KLT-40S on FSUE “PO “Sevmash”.
Project underwent deputy and public hearings in established order.
On the 14th of June 2006 Head of RF Federal agency of nuclear energy S.V. Kirienko and Head of administration of Arkhangelsk region N.I. Kisilev approved protocol “Regarding cooperation in the field of building nuclear power station of small capacity (ATES MM) on the basis of floating power generating plant”. During solemn ceremony FSUE “Concern “Rosenergoatom” signed the following contracts:
– with FSUE “PO “Sevmash” – “Agreement on building and delivery of one non-self-propelled ship – floating power generating plant with two reactor units KLT-40S for ATES MM”, “Agreement of general contract for performing building and mounting works regarding constructing and commissioning shore hydraulic structures and lines within ATES MM”.
– with FSUE “OKBM named after I.I. Afrikantov” – “Agreement for manufacturing and complaex delivery of equipment for two reactor units KLT-40S”.
– with OJSC “Kaluga turbine plant” (Kaluga) – “Agreement on manufacturing and delivery of two steam-turbine block units”.
