Hydraulic testing of half our bodies of Passive Core Flooding System (PCFS) Hydro-accumulators begins at Petrozavodsk Department of AEM-Applied sciences, Russia.
These are supposed for Energy Unit – 2 of Rooppur Nuclear Energy Plant. Eight PCFS Hydro-accumulators will probably be put in in every unit.
Based on Rosatom, the Russian contractor of the Rooppur NPP, hydraulic check is likely one of the most essential last inspections of the tools.
PCFS Hydro-accumulator is full of specifically handled thermally enriched water and the strain within the vessel is raised as much as 4.4 MPa and held for 10 min minimal.
After the strain is launched, the outer floor is inspected visually for any leaks and everlasting deformations.
Hydro-accumulators every having a capability of 120 cubic meters are manufactured from stainless-steel.
It contains three shells and two heads. Ladders and upkeep platforms in addition to different internals are put in inside the physique.
PCFS refers back to the second stage of NPP passive security methods. It’s supposed for the removing of the coolant residual warmth of the reactor major circuit.
An aqueous boric acid resolution heated to a temperature of roughly 60 levels is saved within the Hydro-accumulator throughout operations of the plant.
If for any motive the strain within the major circuit falls under a sure stage, the fluid is robotically fed into the reactor and the lively core is cooled down.
Rooppur NPP is designed and being constructed by the Engineering Division of the Rosatom State Company.
AEM-Applied sciences has been producing principal reactor room tools for each the models of the ability plant.
Based on Bangladesh Atomic Power Fee, the implementing authority of the RNPP, the primary unit of the ability plant was scheduled to start out operation in 2022 and second one in 2024.
However not too long ago the primary unit’s operation was rescheduled to 2024 and second unit to 2025.
