TRIPOLI code

However further studies are performed to confirm margins facing the risk of fast fracture PSA to assess the sensitivity of main parameters which contribute to the risk and deterministic studies, taking in account fluence at the end of reactor life (reassessment with Tripoli code), exhaustive review of transients and selection of dimensioning transients, justification of defect sizes deducted from feedback experience of ISI (In-Service Inspection) and from R D experiments for cracks under the liner. A mechanical study integrating all these parameters is in progress. 

Dosimetry data are analyzed using the neutron transport code TRIPOLI in order to determine neutron fluences for energies over 1 MeV, parameter which indexes the aging results. The primary coolant temperatures are 286 °C for most 900 MWe units, 288 °C for 1300 MWe units and 293 °C for 1450 MWe units. The primary coolant temperature of Chooz-A increased from 257 to 265 °C due to a power uprate.
