Reference excerpt

Nuclear Power and the Environment, sometimes simply called the Flowers Report, was released in September 1976 and is the sixth report of the UK Royal Commission on Environmental Pollution, chaired by Sir Brian Flowers. The report was dedicated to "the Queen's most excellent Majesty." "He was appointed "to advise on matters, both national and international, concerning the pollution of the environment; on the adequacy of research in this field; and the future possibilities of danger to the environment." One of the recommendations of the report was that:

"There should be no commitment to a large programme of nuclear fission power until it has been demonstrated beyond reasonable doubt that a method exists to ensure the safe containment of longlived, highly radioactive waste for the indefinite future." The "Flowers Report" was prompted by a proposal in 1975 to set up an international nuclear fuel reprocessing plant in Windscale. Windscale is a large nuclear facility on the coast of Cumbria in Northwest England that was built after World War II to produce plutonium for England's nuclear weapons program. The facility suffered a leak in 1973, which put it out of commission until the plans for the international nuclear fuel reprocessing plant were proposed. This proposal was met with strong resistance after it became known to the public and as a result, the plans to build the nuclear reprocessing plant were never acted upon. Radioactive waste management and disposal strategies have been enacted since the publishing of "The Flowers Report". This put the responsibility of disposing radioactive waste into the hands of those who are producing it. It was not until 1982 that the Department of the Environment, after their previous method proved to be not as effective as they had hoped, decided to enact stronger guidelines and rules regarding radioactive waste. The responsibility of disposal was then passed over to the government. This led to the Department of the Environment gaining a few new responsibilities: securing the disposal process at an establishment, making sure the method of disposal is safe and well researched, and lastly, keeping the waste secured and away from the public after it has been disposed of. In the United States, as of 2008, uranium ore reserves are primarily kept in Wyoming and New Mexico, totaling an estimated one billion, 227 million pounds. This uranium ore will be turned into fuel that will be used in the operation of nuclear power plants, creating low-levels of radioactive waste. "Spent" uranium fuel becomes radioactive waste as a result of the fission process. This "spent" fuel must be removed and replaced from nuclear power plants every 18 to 24 months; it is then shipped to specifically designed and licensed disposal sites. The U.S. Nuclear Regulatory Commission and the U.S. Department of Transportation carefully control and regulate the management, packing, transport, and disposal of waste.

The Flowers Report The Flowers report is composed of eleven chapters in a compilation of over 200 pages. The chapters cover a wide range of subjects and topics related to radioactive activity.

Chapter One: Introduction The Flower's Report introduction chapter consists of six pages. The report introduces the topics of nuclear technology, future projections on commercial reactors, concerns for left over radioactive waste, other uses of nuclear technology (that will not be the focus of the report), and concerns with development of nuclear reactors. This chapter also gives an arrangement of the entire report's information that acts as an outline for the information presented, including later chapters' topics and main points.

Chapter Two: Radioactivity and Radiobiology The focus of the first half of the chapter is designed to provide basic information about atoms and radiation to aid in later chapters. The first half covers the basics on atoms such as: an atom consists of Neutrons, Protons, and Electrons; the atomic number of an atom determines the amount of protons in one atom; and that protons are roughly 2000 times heavier than electrons (see atom). The concept of radiation is introduced through ionization which is the process of adding one or more electrons to, or removing one or more electrons from, atoms or molecules, thereby creating ions. From there certain particles can cause ionization. The ionizing particles are alpha particles (a type of ionizing radiation ejected by the nuclei of some unstable atoms that are large subatomic fragments consisting of two protons and two neutrons), beta particles (subatomic particles ejected from the nucleus of some radioactive atoms that are equivalent to electrons), gamma particles (electromagnetic energy photon) and energetic neutron radiation (energy released from an atom in the form of neutral particles called neutrons). The second half focuses on knowledge of radiation introduced into the environment and humans. Flower's and his team concluded in 1976 that low levels over a long exposure time can prevent a cell from dividing or further damaging genetic information. Other topics covered are the effects of plutonium in the body. For instance, animals being susceptible to radiation causes birth defects among the litter. Chapter two concludes with a concern of radiation affecting an entire species of animals as opposed to a group.

Chapter Three: Nuclear Power Chapter Three focuses on nuclear power. This chapter main concentration is on nuclear reactors and the basic physical principals of which reactor operation is based. An understanding of the different types of reactors that are in use or plan to be used is given. It also accounts for the nuclear fuel cycle and the operations that are involved in the fabrication and treatment of nuclear fuel. It begins with the extraction of uranium from the mine to the fuel fabrication plant and then to reactors. Furthermore, it incorporates the removal of spent fuel and its treatment to extract material suitable for incorporation of fresh fuel along with the treatment and disposal of wastes.

Worked examples

Example 1 — a first encounter with Nuclear Power and the Environment

Start with the simplest possible case. Write down what Nuclear Power and the Environment claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nuclear Power and the Environment before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nuclear Power and the Environment ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nuclear Power and the Environment

In research: Nuclear Power and the Environment appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nuclear Power and the Environment in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nuclear Power and the Environment is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1976 in the environment, 1976 non-fiction books, Books about nuclear issues, so understanding it makes those chapters shorter.
In everyday life: Look for Nuclear Power and the Environment outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
