(1) Backup pumps for the secondary loop water system automatically turn on.

(2) 0 sec The pumps in the secondary loop shut down automatically, due to a slight malfunction.

(3) Secondary loop includes current transformer, voltage transformer, secondary wiring, electronic energy meter and burden monitoring units.

(4) The PT secondary loop voltage drop equals to the product of the PT secondary loop impedance and the loop current.

(5) The PT secondary loop voltage drop is a changing amount and has the characteristics of indirection and certain randomness.

(6) Operator notices that the valves for the secondary loop backup pumps are off.

(7) 4 sec Backup pumps within the secondary loop automatically turn on.

(8) It's conclusion shows that SCAS can be not only used to calculate 16N and 17N source term in secondary loop without reactor core system, but also use...

(9) 8 min An operator notices that the valves for the backup pumps in the secondary loop are off. He opens the valves. The secondary side now operating normally.

(10) The flow accelerated corrosion(FAC) to equipments by the high flux feed water occurs easily in steam and water systems of secondary loop of PWR .

(11) The results of transient test events show that the simulation successfully fulfills control and protection function of primary and secondary loop in NPP.

(12) By using control strategy of parameter parameters self-turning fuzzy PID, lead secondary loop the automatic doing control offers excellent dynamic response and stable characteristic.

(13) The separation of the protection loop and measurement loop can reduce the PT secondary loop current effectively, but can't guarantee which meets the relevant rules.

(14) SCAS is the source term code to calculate steam activation products in secondary loop of reactor, which is developed by Nuclear Power Institute of China.

(15) 8 min An operator notices that the valves for the backup pumps in the secondary loop are off. He opens the valves.

(16) As an example[Sentencedict.com], the capability of the simulation model was validated by taking simulation of rapidly power reducing condition of secondary loop.

(17) Theoretically the net voltage fluctuation and the change of secondary loop impedance is shown by the effective value of welding current, and by compensating the constant current control is realized.

(18) 2 sec Because heat is no longer being transferred to the secondary loop, water pressure and water temperature in the primary loop rise. This is normal and no cause for concern.
