Owing to four faulty valves AERB has decided to delay Kudankulam nuclear power plant

India's nuclear regulator ordered replacement of four defective plug valves of the system that cools the reactor of Kudankulam nuclear power plant after the problem was detected during ongoing pre-commissioning tests.
The defect in the components of the four valves - there are thousands of such devices in a nuclear reactor - was found during pre-commissioning tests early this year, officials said.
"During testing of thousands of indian butterfly valves installed in the plant, the performances of four valves of a particular type were found deficient," R Bhattacharya, Secretary, Atomic Energy Regulatory Board (AERB) said in a statement here Friday evening.
Officials said that the butterfly valves were in the Emergency Core Cooling System (ECCS) that removes heat from a nuclear reactor under extreme components. On finding the defective valves, the Nuclear Power Corporation of India Limited (NPCIL) had procured replacements through its Russian collaborators.
"These valves are requiring larger efforts to get corrected," another official said but added that this was not an unprecedented development.
AERB Chairman S.S. Bajaj said the new components have been procured and were being assembled.
The programme 'requires formulation of detailed quality assurance plans specifying the sequence of activities and identifying the quality control points at which physical inspection/verifications are performed by the Quality Assurance Groups of contractors/manufacturers as well as independently by NPCIL'.
It added that the AERB had cleared for an 'initial fuel loading' at the plant as part of the commissioning activities and that "satisfactory demonstrations of functional capability are a prerequisite for considering the plant suitable for operating phase."

The hydraulic valve device precision & advantages and disadvantages

Appearance of Pneumatic Butterfly Valves, the main difference is that they rely on the power source of the drive. Hydraulic valve stand hydraulic power source, the higher oil pressure to push the piston to drive the valve switch. The precision requirements of the hydraulic actuator is very high, a little a bit processing undeserved cause hydraulic oil leak, the oil cylinder is likely to be scrapped. Is the cause of hydraulic pneumatic valve price is expensive. Hydraulic valve output torque relative to the pneumatic valve, power is strong. Hydraulic valves are widely used in water, steam, water, paper, petrochemical, natural gas, solution and pulp two-phase mixed flow medium, and the dust and gas, powder conveying solid medium containing particles fluid is the ideal equipment, using the hydraulic operation, is more convenient for management automation, remote control, hydraulic signal device, can be used for automation and centralized control.
Hydraulic device is made of hydraulic pressure valves to regulate the opening and closing or drive it by control, motivation and actuators are composed of three parts. Control part consists of a pressure control valve, flow control valves, directional control valves and electric control system composition. Drive by the motor or pneumatic motor, hydraulic pump, tank and so on, is the effective power on the electric or pneumatic motor axis into hydraulic transmission fluid pressure can. Actuator has two kinds, one kind is hydraulic cylinder actuators, realize reciprocating linear motion; The other is a hydraulic motor actuators, realize the rotary motion, the advantages and disadvantages of hydraulic device is as follows:
A, hydraulic valve device
1) the simple and compact structure, small volume;
2) is stable and reliable;
3) can get a lot of output torque;
4) the output torque can be accurately by constant pressure relief valve adjustment, including the opening and closing torque adjustment, even can be reflected directly by hydraulic pressure instrument;
5) easy speed regulation;
6) in power, the sudden accident, still can use accumulator to one or several power operation. The long distance pipeline emergency shut-off valve and wellhead discharge automatically
Valve has a special meaning.
Second, the hydraulic valve gear faults
1) the oil temperature is greatly influenced by environmental temperature, the oil temperature change caused by oil viscosity changes, affect the operation;
2) piping trouble, easy to produce leakage;
3) is not suitable for the signal to produce a variety of operations (such as signal amplification, memory, logic, arithmetic).
