The differences in other parameters can be explained by the differences in the power response and possible differences in initial conditions (i.e., in terms of initial steam generator pressure).Peter YarskyUnited States Nuclear Regulatory CommissionAndrew Bielen...
After the break of the feedwater line, propagation of the pressure wave along the flow line inside the steam generator was clearly and pertinently observed in all the tests. In terms of the reproducibility of the test results, characteristics of the dynamic pressure in both the FLB-DS-01 and...
The ''RCS Dynamic'' represents the RCS parameters, such as temperature, pressure, and void fraction, as shown in Fig. 13. 6. HUPESS The human performance evaluation support system (HUPESS) has been developed to effectively measure the operator's response when the personnel perform selected ...
The main steam pipe connecting the isolated island and turbine building is subjected to the seismic response difference of different buildings. Isolation t... D Kong,W Liu,Z Li,... - 《International Journal of Pressure Vessels & Piping》 被引量: 0发表: 2024年 Westinghouse, KHNP seek to se...
Lessened heat transfer to the secondary side caused by earlier actuation of the safety injection pumps had more influence on the secondary pressure of the affected steam generator than the break flow. The break flow was discharged as single-phase water in both tests....
The thermal-hydraulic condition in the region of secondary side of APR1400 steam generator is obtained using the ATHOS3 code. The effective mass for modal analysis is calculated using the void fraction, enthalpy, and operating pressure information from ATHOS3 code result. With the effective mass ...

The GASFLOW code calculates the distribution of the steam, hydrogen, and air in the containment during the severe accident using the MAAP results as the mass and energy source terms (Figure 4 and Figure 5). The initial temperature and pressure of the air in the containment are assumed as 30...
