The void coefficient has fhe strongest effect in BWR ( Boiling Water Reactors ). In BWR the void coefficient is negative. This negative void coefficient can create lots of problem in an industry. Sudden pump failure, sudden reactor power increase or unstable power oscillations. This can cause vast damage in the Industry.
Add Answer to:
The void coefficient has the strongest effect in which reactor? CANDU PWR LMFBR BWR
9) Which of these reactor types has the weakest moderating coolant? LMFBR BWR PWR AGR
9) Which of these reactor types has the weakest moderating coolant? LMFBR BWR PWR AGR

A reactor, which will contain corrosive liquid, has been design. If the reactor is made of mild steel, the initial installed cost will be $6000, and the useful life period will be 4 years. Since stainless steel is highly resistant to the corrosive action of the liquids, stainless steel, as the material of construction, has been proposed as an alternative to mild steel. the stainless steel reactor would have an initial installed cost of $16000. The scrape value at the...

Consider a chemical reactor that has a constant heat release. In this reactor, there are 1-m long cylindrical pipes (L) have inner diameter of 25 mm (D) and Helium gas enters each of the pipe at 400K (Ti) and exits at 800K (Te) that is used to cool the reactor at atmospheric pressure and has mass flow rate as 0.02 kg/s. Determine; (Helium properties at Tf; ρ=0.08 kg/m3; Cp=5200 J/kg.K; µ= 32*10-6 kg.m/s ; k=0.23 W/m.K; Pr= 0.72) the surface...
