In summary, the conversation discusses various topics related to power generation and thermodynamic cycles. The first question asks about the advantages and disadvantages of using nitrogen as a cooling gas in a PBMR compared to helium. The second question is about ways to increase power in a Brayton cycle while maintaining pressure and temperature. The third and fourth questions compare the ideal cycles of Brayton and Atkinson, and Diesel and Otto, respectively. The final question considers the changes in losses during compression and expansion in different cycles.

I would need help, if there is someone willing to help...

Q:

·What are advantages and disadvantages of nitrogen as cooling gas in PBMR comparing with helium?


·On witch way is possible to increase power of Brayton cycle to act on compressor side and in the same time greatest pressure and temperature to remain the same?


·Which one of ideal cycles is better, Brayton or Atkinson?

·Which one of ideal cycles is better, Diesel or Otto?

·Why losses during compression and expansion rapidly change sequence in comparing Diesel and Otto, Brayton or Atkinson cycle?

Thanks

What is a Pbmr?

A Pbmr, or Pebble Bed Modular Reactor, is a type of nuclear reactor that uses small fuel particles instead of traditional fuel rods. These particles are contained in graphite pebbles and are able to withstand higher temperatures, making them more efficient and safer than traditional reactors.

How does a Pbmr work?

A Pbmr uses a process called high temperature gas-cooled reactor (HTGR) technology. The nuclear fuel is formed into small particles and then encased in graphite pebbles. These pebbles are then stacked together in a core, and helium gas is used to transfer heat from the reactor to a power conversion system, which then generates electricity.

What is the advantage of using a Pbmr?

Pbmr technology offers several advantages over traditional nuclear reactors. These include increased safety due to the use of small fuel particles that are less likely to overheat, improved efficiency due to the use of helium gas as a coolant, and the ability to use the waste heat from the reactor for other purposes, such as desalination or hydrogen production.

What is a thermodynamic cycle?

A thermodynamic cycle is a series of processes that a system undergoes in order to convert energy from one form to another. In the context of Pbmr, a thermodynamic cycle is used to convert the heat generated by the nuclear reaction into electricity.

What are the different types of thermodynamic cycles used in Pbmr?

There are several types of thermodynamic cycles that can be used in Pbmr, including the Brayton cycle, the Rankine cycle, and the Stirling cycle. Each of these cycles has its own advantages and disadvantages, and the choice of cycle depends on the specific requirements of the reactor and its intended purpose.
