In summary, there are a few differences between APWR and PWR in terms of core and nuclear fuel. However, it is possible to use PWR data to calculate nuclear flux and burn up for APWR. As for the AP1000, it uses a 14-ft active fuel length and standard 17x17 fuel with 14-ft pellet stack. More technical information can be found on the NRC website in the Design Control Document.

What's the significant difference between APWR and PWR in terms of core and nuclear fuel, I mean, if we want to calculate nuclear flux and burn up of APWR, can we use PWR data instead?

btw, anyone knows a site that provides AP1000 datasheet or specification?

The AP1000 uses a 14-ft (4.27 m) active fuel length, similar to that used by South Texas and EdF 1300 MWe plants. The fuel rods are more or less standard 17x17 fuel with 14-ft pellet stack.

One can find technical information on the NRC website in the Design Control Document, particularly sections 4.1 and 4.2.

For the AP1000, see

Items 134 - 139.

1. What is the difference between an APWR and a PWR?

The main difference between an APWR (Advanced Pressurized Water Reactor) and a PWR (Pressurized Water Reactor) is their design and fuel type. APWRs use advanced technology, such as a larger core and higher operating temperatures, to improve efficiency and safety. They also use mixed oxide fuel, which contains both uranium and plutonium, while PWRs typically use only enriched uranium fuel.

2. How do the core and fuel data compare between APWRs and PWRs?

The core and fuel data for APWRs and PWRs are quite different due to their design and fuel type. APWRs have a larger core size and higher operating temperatures, which allows for a higher power output and longer operating cycles. They also have a higher burnup rate, meaning the fuel can be used for a longer period of time before needing to be replaced. Additionally, the mixed oxide fuel used in APWRs has a higher energy density compared to the enriched uranium fuel used in PWRs.

3. Which type of reactor has better performance and efficiency?

Both APWRs and PWRs have their own advantages and disadvantages in terms of performance and efficiency. APWRs have a higher power output and longer operating cycles, making them more efficient in terms of energy production. However, PWRs have a simpler design and are more widely used, making them more reliable and easier to maintain. Ultimately, the performance and efficiency of each reactor will depend on its specific design and operating conditions.

4. What safety considerations are different for APWRs and PWRs?

While both APWRs and PWRs are considered to be safe and reliable nuclear reactors, there are some differences in their safety considerations. APWRs have a larger core size and higher operating temperatures, which require more advanced safety features to prevent accidents. They also use mixed oxide fuel, which presents different safety concerns compared to the enriched uranium fuel used in PWRs. Overall, both types of reactors have extensive safety measures in place to ensure the protection of the public and the environment.

5. Which type of reactor is more commonly used?

PWRs are currently the most commonly used type of nuclear reactor worldwide, accounting for around 60% of all nuclear power plants. APWRs, on the other hand, are a newer and less widely used technology. As of 2021, there are only a handful of operational APWRs in the world, with more under construction or planned. The choice between using an APWR or PWR will depend on various factors, including the specific needs and resources of each country or region.
