Selection of Retrieval Techniques for Irradiated Graphite During Reactor Decommissioning - 11587
WM2011 Conference, February 27 - March 3, 2011, Phoenix, AZ Selection of Retrieval Techniques for Irradiated Graphite during Reactor Decommissioning - 11587 D.J. Potter*, R.B. Jarvis*, A.W. Banford*, L. Cordingley*, and M. Grave** * National Nuclear Laboratory, Chadwick House, Birchwood Park, Warrington, Cheshire, WA3 6AE, UK ** Doosan Babcock, Baltic Business Centre, Gateshead, NE8 3DA, UK ABSTRACT Globally, around 230,000 tonnes of irradiated graphite requires retrieval, treatment, management and/or disposal. This waste has arisen from a wide range of reactors, predominantly from the use of graphite moderated reactors for base-load generation, but also from experimental research facilities. Much of the graphite is presently still in the reactor core while other graphite is stored in a variety of forms in waste stores. The first step in the management of this significant waste stream is retrieval of the graphite from its present location. Doosan Babcock and the UK National Nuclear Laboratory are participants in the CARBOWASTE European research project which brings together organisations from a range of countries with an irradiated graphite legacy to address the graphite waste management challenge. This paper describes the issues associated with retrieval of graphite from reactors, potential approaches to graphite retrieval and the information needed to select a particular retrieval method for a specified application. Graphite retrieval is viewed within the context of the wider strategy for the management of irradiated graphite waste streams. The paper identifies the challenges of graphite retrieval and provides some examples where modelling can be used to provide information to support retrievals design and operations. INTRODUCTION A four year collaborative European Project ‘Treatment and Disposal of Irradiated Graphite and other Carbonaceous Waste (CARBOWASTE)’ was launched in April 2008 under the 7th EURATOM Framework Programme [1]. -

South Stream Becomes Serbian Stream
Serbia: South Stream becomes Serbian stream The position of the Republic of Serbia as a candidate for EU membership on the one hand and cooperation with Russia on the other allows this country to position itself as an intermediary between the two sides, between the East and the West. The re-export of Russian gas to other countries is exactly such an opportunity. While Russia is under EU sanctions and while the official Union policy reduces dependence on Russian gas (despite obvious contradictions like North Stream 2), Russia cannot sell gas to the EU under free market conditions. Serbia, as a still non-member of the Union, does not oblige to follow the same rules. The specific position in which Serbia is located allows this country to use it for its economic progress. After the Kremlin summit at the end of December last year, there were rumors that Russia will begin to change Russia’s natural gas supply agreement to Serbia, and allow this country to sell Russian gas to other countries, and now we are closer to realizing that plan. The Russian newsletter announced that Moscow will put an end to the agreement that stipulates that Russian natural gas can only be sold on the Serbian market. The agreement covers the period from 2012 to 2021 and envisages the delivery of up to five billion cubic meters per year. In order for this to be possible, Serbia will have to build new pipelines. At present, its pipes are connected only to Bosnia and Herzegovina, but since December, construction of a special branch of the gas pipeline from Dimitrovgrad to Niš has begun. -

Bankside Power Station’S Former Design Effect the Restoration and What Effect Did the Changes Have?
INTERNATIONAL BACCALAUREATE EXTENDED ESSAY An Exploration into how Herzog & de Meuron designed the Tate Modern by considering the industrial attributes that affect the function of the museum. How did the Bankside Power Station’s former design effect the restoration and what effect did the changes have? Name: Maxim Goldau Student Number: Subject: Visual Arts King William’s College Centre Number: 26th September 2014 Word Count: 3791 1 Abstract: This essay explores the approach Herzog & de Meuron took to restore and design the Tate Modern. The building being restored was the Bankside Power Station, designed by Giles Gilbert Scott in 1947. The Power Station was designed with an industrial purpose at its heart. I wanted to discover what procedure was necessary to adapt a former industrial building to serve a very opposing purpose, which led me to my research question: “How did the Bankside Power Station’s former design effected the restoration and what effect did the changes have?” I proceeded by analysing the original structure of the Bankside Power Station and in which ways Herzog & de Meuron changed elements of the building; especially the reasons for changing sections of the building. I analysed the single parts of the former Power Station were investigated to gather information about the approach, ideas and intended effects. To investigate the structure of the Tate Modern, I was analysed various layouts and images. My main sources were online articles, essays and the homepages of the artists, the Tate and Herzog & de Meuron. Most articles were just documenting and informing the readers with the very basic information, but I found the website of Herzog& de Meuron reflected their thinking process. -

The Journal of U the London Underground Railway
THE JOURNAL OF U THE LONDON UNDERGROUND RAILWAY SOCIETY I ssue No 104 Volume 9 No 8 August 1970 N EVEN GREATER POWER FAILURE CHAOS At 17.1 5 on Monday 6t h July 1970, at the height of the evening r ush hour, a pr otective relay operating a D circuit breaker t r i pped t oo soon and effectively cut off t he power supply t o a very l arge section of the central part of the Undergr ound. The only secti ons not affected at all were the Met r opo l i t an north of Bake r Street E (which is s upplied from the Nat i onal Grid) and the Victoria Line (which i s fed by a direct cabl e from Lots Road). Some sections were back in service fairly soon, but others, notably he eastern part of the Central R Line were out of action for a l ong time. It seems that most services were interrupted for about fifty minutes, and that all services were running normally again by 19.000 G The circuit breaker concerned was at Greenwich Power Station, and its failure broke the link between Greenwich and Lots Road, and me ant effectively that power generated at both these s tations could not be f ed to the system. R There are two extremely disqui eting features of this failure; communications with staff and passengers broke down compl etely, resul ting in numerous stations becoming dangerously overcrowded and, much more serious, o almost a quarter of a million passengers being trapped in s tationary trains in the tunnels at a time when the temperature outside was 77°F - no-one seems t o know what U the temperature rose t o in the trains. -
Bankside Power Station: Planning, Politics and Pollution
BANKSIDE POWER STATION: PLANNING, POLITICS AND POLLUTION Thesis submitted for the degree of Doctor of Philosophy at the University of Leicester by Stephen Andrew Murray Centre for Urban History University of Leicester 2014 Bankside Power Station ii Bankside Power Station: Planning, Politics and Pollution Stephen Andrew Murray Abstract Electricity has been a feature of the British urban landscape since the 1890s. Yet there are few accounts of urban electricity undertakings or their generating stations. This history of Bankside power station uses government and company records to analyse the supply, development and use of electricity in the City of London, and the political, economic and social contexts in which the power station was planned, designed and operated. The close-focus adopted reveals issues that are not identified in, or are qualifying or counter-examples to, the existing macro-scale accounts of the wider electricity industry. Contrary to the perceived backwardness of the industry in the inter-war period this study demonstrates that Bankside was part of an efficient and profitable private company which was increasingly subject to bureaucratic centralised control. Significant decision-making processes are examined including post-war urban planning by local and central government and technological decision-making in the electricity industry. The study contributes to the history of technology and the environment through an analysis of the technologies that were proposed or deployed at the post-war power station, including those intended to mitigate its impact, together with an examination of their long-term effectiveness. Bankside made a valuable contribution to electricity supplies in London until the 1973 Middle East oil crisis compromised its economic viability. -

THE VIEW from MY WINDOW by GLYN ENGLAND
SUPPLEMENT TO THE HISTELEC NEWS AUGUST 2004 THE VIEW FROM MY WINDOW An historical perspective of the Electricity Supply Industry. by Glyn England JP, BSc(Eng), Hon.DSc(Bath), FEng,FIEE,CBIM Extracted from a Presidential Address given by Glyn England, then Chairman of the CEGB, on 2nd April 1982 to the Metals and Materials Association meeting at Bath University. ------------------------------------------------------------------------------------------------------------------------------------------------ INTRODUCTION I propose to interpret this title metaphorically as well as literally, using a few landmarks, past and present, as pegs for : - reflections on some aspects of the history of electricity supply in this country; considering some lessons that can be learnt from that past experience; and a few personal thoughts about the future, together with a mention of some of the CEGB's present preoccupations. In other words, I intend to think aloud about how things seem to me, from where I sit in my office on the fifteenth floor of the CEGB's headquarters building, Sudbury House, in one of the most historic parts of the City of London. Indeed, the industry as we know it today was really started by a big step forward in high-temperature materials technology which took place about 100 years ago. It was the development, by Swan and Edison, of a filament of carbon, which could be heated in a vacuum to incandescent temperatures that resulted in the production of the first practical incandescent lamp. We all know what a great impetus that gave to electrical technology. SPATE OF CENTENARIES I have mentioned one centenary. In fact, we in electricity supply are having quite a spate of centenaries about this time.
