Housing of reactor coolant pumps (RCPs) made for second unit of Rooppur Nuclear Power Plant has successfully undergone Fit-up check in Russia.

The check was conducted at Petrozavodsk Branch of “AEM-Technologies”.

It was done in presence of the representatives from Bangladesh Atomic Energy Commission (BAEC) and the authorised organisation “VO Safety” recently, said a press release.

Each of the two units of the plant will have a set of four coolant pumps with spherical housing.

At all manufacturing stages the RCPS housings are subject to various types of inspection, including dye-penetration test, ultrasonic test, and radiographic test among others.

Fit-up check is one of final tests, when assembility of the RCPS spherical housing with the suspension component (spacer) and with the inner cone is checked.

The RCP housings are the items belonging to the first safety class.

At a nuclear power plant, the reactor coolant pump set provides coolant circulation from the reactor to the steam generators and operates under the coolant pressure of about 160 atmospheres and at a temperature of 300 degrees.

The RCP will be sent to the Bangladesh in separate components. Hence after successful checking, it is to be dismantled for painting before shipment.

Rooppur NPP is being designed and constructed under the Russian project.

Designing and construction of the plant is performed by Engineering Division of Rosatom State Corporation.

The plant is going to consist of two power units equipped with two VVER reactors, the life cycle of which to be 60 years with an option to extend for another 20 years. Capacity of every unit will be 1200 MW.

The company “AEM-Technologies” manufactures basic equipment of reactor hall for two power units of the plant.

It is a part of machine-building division of Rosatom State Corporation – Atomenergomash.
