At least one secondary piping loop branches away from the primary loop and returns downstream to the primary loop via a pair of closely spaced tees in a primary/secondary piping loop interface apparatus. The primary/secondary piping loop interface apparatus is of unitary construction and includes a...
PRIMARY/SECONDARY PIPING LOOP INTERFACE APPARATUSA primary-secondary loop piping system includes at least one boiler in fluid communication with a primary piping loop and at least one primary loop pump in the primary piping loop. At least one secondary piping loop branches away from the primary ...
The article presents a comparison of the operational modes and performance of primary/secondary (P/S) loop and primary-loop-only-variable-flow (PLOVF) control system. It states that (P/S) loop uses a qualitative and quant...
Two main loops are 6" diam pipe, and common piping is 6" diam with check valve. Problem: When system sees low load and secondary variable flow pumps are operating at low flow, chillers trip out due to low flow conditions (from constant flow primary pumps). Question: Does ...
The perennial operation of nuclear power primary loop piping leads to deterioration of the piping and the potential risk of leakage. At present, there is no reliable technology to detect the leakage directly. This paper proposes a method to obtain the piping deterioration evolution trend based on ...

The secondary circuit design is optimized to enable good heat removal by air in natural convection, such as in situations like “Fukushima” where both the cooling water and alternating current (AC) power supply are lost. For this purpose, several measures are taken: – A secondary loop design...
Hose of the liquid-cooled door for connecting to branches of the primary loop Material: compliant with the requirements on contact with the working medium. For details, see the section about CDU and secondary pipe material requirements in the Liquid Cooling Deploymen...
PROBLEM TO BE SOLVED: To provide a reliable internal pump and light water nuclear power plant primary system piping by reducing the increase in frictional loss of a flow by the gap part of the internal pump to inhibit of secular change in recirculation system piping and a main steam pipe whi...
heat in the steam generator4to secondary water which passes through the secondary part of the generator. The secondary water circulates in a closed loop in a secondary cooling system (not shown). It evaporates as it passes through the generator4, the steam so produced driving a steam turbine...
