Main results of AES 92 assessmentMain results of AES 92 assessment

The AES-92 plant design has been developed as a Standard Design in the Russian Federation context. Even so, the compliance assessment performed and reported in the EUR Volume 3 AES-92 Subset shows a good level of compliance of the AES-92 plant design with the EUR policies, objectives and requirements.

Many "compliances with objectives" have been identifiedRussian Federation specific regulatory contextThe designer intends to demonstrate compliance during the detailed design phase

Many "compliances with objectives" have been identifiedRussian Federation specific regulatory contextThe designer intends to demonstrate compliance during the detailed design phase

Compliance with objectives (CWO):the design is supposed to achieve the objective of the requirement; either a different approach from the EUR one is used to achieve the same objectives, or the approach is not yet defined

Compliance with objectives (CWO):the design is supposed to achieve the objective of the requirement; either a different approach from the EUR one is used to achieve the same objectives, or the approach is not yet defined


Compliance with the EUR objectives:PSA targets: the AES 92 results are quite low for the internal events, thus the EUR objectives are reachable, but impact of certain hazards and initiating events has not been assessed yetSafety classification: the Russian Standard OPB88/97 based on different principles than EUR. The safety classified part may bea bit larger than allowed in EUR.Primary and Secondary Containment performance: balanced design achievable because of big reserve for optimisation

Compliance with the EUR objectives (continued):Passive Heat removal in Design Extension Conditions for 72 h: reliable operation of Passive Heat Removal System beyond 24 h depends on results of tests on PHRS and gas-removal system Reactor Pressure Vessel: 60 year-lifetime possible by construction changes, improved material properties, surveillancespecimensAutomatic isolation of Residual Heat Removal System located outside primary containment: could be done on customer demand

Compliance with the EUR objectives (continued):EUR Seismic spectra & soil conditions: adaptable designFuel & core performance

Average FA Burn-up: 51 MWd/kgHM (55 for EUR)Type of fuel: initially UO2 core, 50% MOX feasibleLength of fuel cycle: initially 12 months, but capability for 24

Codes & standards: use of Euronorms looks possibleHV Grid requirements: comparable voltage-frequency fields

Several Non-Compliances have been identifiedOverall construction time: 60 months from first concrete to commercial operation, no reduction foreseen for AES 92Digital I&C and computerised Man-machine interface

for AES 92 partially computerised control room normal operation handled via fully computerized MMI safety systems dealt through conventional controlswith duplication of information on displays of computerized MMI

Refuelling & regular maintenance outage duration: 28 days for AES 92 (20 days requested in EUR)Spent fuel storage capacity: 642 cells for AES 92 (instead of 738 cells according to EUR, mainly for MOX spent fuel)

Non-compliance (NOC):the design does not meet the requirement; an assessment of the gap importance must be given.
