Is the radial peaking factor same as normalized radial power profile?
Vnt666Skr said:Thanks Astronuc.
Is it defined at each axial/radial position? Suppose I have a power profile of a single pin. How do I find out the peaking factors at various locations in the axial and radial direction?
A peaking factor would be determined from the local power density (or linear power) divided by the core average power density (or linear power). The average power density is found from the thermal rating of the reactor core divided by the total length of active fuel. The local power density is calculated with a core simulation code (e.g., SIMULATE or other proprietary code) which solves a multi-group neutron diffusion or transport problem. The codes calculate the neutron flux and local enrichment, which includes effects of depletion and transmutation, and from these determine the fission density, from power density is calculated.Vnt666Skr said:Thanks Astronuc.

A peaking factor is a measure of the maximum power demand compared to the average power demand over a specific period of time. It is important in power profile analysis because it helps to determine the capacity and reliability of a power system, as well as the potential for overloading or underutilization of resources.
A peaking factor is calculated by dividing the maximum power demand by the average power demand over a specific period of time. This period of time can vary depending on the application, but is typically measured in hours, days, or seasons.
A power profile is a graphical representation of the power demand over a specific period of time. It is often used in conjunction with peaking factor analysis to better understand the patterns and trends of power usage. Peaking factor is a quantitative measure that helps to characterize the power profile.
Yes, a high peaking factor can be a cause for concern in certain situations. For example, if the peaking factor is consistently high over a long period of time, it may indicate that the power system is reaching its maximum capacity and may require upgrades or improvements to meet the demand. However, a high peaking factor during a short-term event, such as a heat wave, may not necessarily be a cause for concern.
Peaking factor and power profile analysis can provide valuable insights into the patterns and trends of power usage, which can help in planning for future power needs. By understanding the peak demand periods and the corresponding peaking factor, power systems can be designed and managed more effectively to meet the demand and avoid overloading or underutilization of resources.
