Astrofisika

 

"Terkadang Kita merasa hanya berada pada satu ruang dan waktu tanpa menyadari mungkin ada ruang dan waktu serta semesta lain yang ada selain apa yang kita rasakan saat ini"

Bagian Terakhir Perkuliahan Astrofisika

Frontiers and Controversies in Astrophysics

Lecture 24 - The Multiverse and Theories of Everything

verview:

Professor Bailyn begins the class with a discussion of a recent New York Times article about the discovery of a new, earth-like planet. He then discusses concepts such as epicycles, dark energy and dark matter; imaginary ideas invented to explain 96% of the universe. The Anthropic Principle is introduced and the possibility of the multiverse is addressed. Finally, biological arguments are put forth for how complexity occurs on a cosmological scale. The lecture and course conclude with a discussion on the fine differences between science and philosophy.

Components

The key components common to most types of nuclear power plants are:

• Nuclear fuel
• Nuclear reactor core
• Neutron moderator
• Neutron poison
• Coolant (often the Neutron Moderator and the Coolant are the same, usually both purified water)
• Control rods
• Reactor vessel
• Boiler feedwater pump
• Steam generators (not in BWRs)
• Steam turbine
• Electrical generator
• Condenser
• Cooling tower (not always required)
• Radwaste System (a section of the plant handling radioactive waste)
• Refueling Floor
• Spent fuel pool
• Nuclear safety systems
  
  
  • Reactor Protective System (RPS)
  • Emergency Diesel Generators
  • Emergency Core Cooling Systems (ECCS)
  • Standby Liquid Control System (emergency boron injection, in BWRs only)
• Containment building
• Control room
• Emergency Operations Facility
• Nuclear training facility (usually contains a Control Room simulator)

Nuclear power is produced by controlled (i.e., non-explosive) nuclear reactions. Commercial and utility plants currently use nuclear fission reactions to heat water to produce steam, which is then used to generate electricity. In 2009, 13-14% of the world's electricity came from nuclear power.^[1] Also, more than 150 naval vessels using nuclear propulsion have been built.

 (Mr. Angga Fuja W.)

The economics of new nuclear power plants is a controversial subject, since there are diverging views on this topic, and multi-billion dollar investments ride on the choice of an energy source. Nuclear power plants typically have high capital costs for building the plant, but low fuel costs. Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear plants. Cost estimates also need to take into account plant decommissioning and nuclear waste storage costs. On the other hand measures to mitigate global warming, such as a carbon tax or carbon emissions trading, may favor the economics of nuclear power.
