Sellafield Magazine: Issue 7
Editor's Letter Editor’s Letter British engineering making a hole lot of difference page 54 his issue of Sellafield Magazine comes later than originally advertised. As a publicly funded organisation we minimised our communication Tactivity in the run up to the General Election in June. It is our home within the civil service and as a subsidiary of the Nuclear Aspiring young writers visit Sellafield Decommissioning Authority that prompted another highlight from the page 70 last few months. Our digital home has moved. We are now part of the GOV.UK platform. You can read more about the transition of our website on page 63 and don’t forget to save our new address to your favourites: www.gov.uk/sellafieldltd We have been busy since our last issue so our pages are bursting with stories about the progress we are making on the Sellafield site. You can read about the doors we have installed into the side of an old waste silo on page 54; about the robots our supply chain partner Forth Engineering have developed to help us complete radiological surveys on page 12; and find out everything you need to know about our Site Ion Exchange Plant in the latest of our ‘In Focus’ series on page 50. Our new website: www.gov.uk/sellafieldltd is now live page 63 At a corporate level, we have published our new strategy as well as our transformation plan. Together they provide an overview of our direction and our approach to fundamental and far-reaching changes in our organisation. -
小型飛翔体/海外 [Format 2] Technical Catalog Category
小型飛翔体/海外 [Format 2] Technical Catalog Category Airborne contamination sensor Title Depth Evaluation of Entrained Products (DEEP) Proposed by Create Technologies Ltd & Costain Group PLC 1.DEEP is a sensor analysis software for analysing contamination. DEEP can distinguish between surface contamination and internal / absorbed contamination. The software measures contamination depth by analysing distortions in the gamma spectrum. The method can be applied to data gathered using any spectrometer. Because DEEP provides a means of discriminating surface contamination from other radiation sources, DEEP can be used to provide an estimate of surface contamination without physical sampling. DEEP is a real-time method which enables the user to generate a large number of rapid contamination assessments- this data is complementary to physical samples, providing a sound basis for extrapolation from point samples. It also helps identify anomalies enabling targeted sampling startegies. DEEP is compatible with small airborne spectrometer/ processor combinations, such as that proposed by the ARM-U project – please refer to the ARM-U proposal for more details of the air vehicle. Figure 1: DEEP system core components are small, light, low power and can be integrated via USB, serial or Ethernet interfaces. 小型飛翔体/海外 Figure 2: DEEP prototype software 2.Past experience (plants in Japan, overseas plant, applications in other industries, etc) Create technologies is a specialist R&D firm with a focus on imaging and sensing in the nuclear industry. Createc has developed and delivered several novel nuclear technologies, including the N-Visage gamma camera system.

With the likes of Richard Attenborough or Jeremy Vine, Hawking rose to the status of documentary voice and British national public treasure. He also helped build bridges between science and the British public both through books and documentaries. The latter in particular have held a place of pride in the popularising techniques regarding the sometimes-esoteric world of natural or experimental sciences. As a television sub-genre, documentaries are distinct from news-providing or fiction programmes but borrow elements from both. For Bill Nichols, “The appearance of documentary involves the combination of three pre- existing elements--photographic realism, narrative structure, and modernist fragmentation—along with a new emphasis on the rhetoric of social persuasion.”1 It means that a documentary is based on chronicling the “real” through images and sounds, mostly with an activist intent. -
Sellafield What to Do in a Radiation Emergency Booklet
WHAT TO DO IN AN Emergency At Sellafield This information is prepared for everyone within the Detailed Emergency Planning Zone and the Inner Emergency Planning Zone for the Sellafield Site. EMERGENCY INFORMATION Listen to local radio. Monitor social media platforms. Dial the Sellafield Emergency Information Line on 29th September 2021 It is important that you study this booklet carefully and keep it in a safe and prominent place. WHAT TO DO IN AN EMERGENCY Introduction • This booklet gives advice on what to do in the event of an emergency at the Sellafield Site. • Sellafield is Europe’s largest single nuclear site and stores and handles industrial size quantities of radioactive material. Although unlikely, an emergency could occur involving material being stored and processed on the Site. In addition, Sellafield also holds a large inventory of other hazardous substances and again although unlikely an emergency could occur involving the chemicals being utilised on the Site. • It must be stressed that the possibility of such emergencies occurring is remote and that the design and operation of all plants on the site are independently monitored by the Office for Nuclear Regulation (ONR), Health and Safety Executive (HSE) and Environment Agency (EA). • Current assessments of the radiological hazards indicate that areas between 6.1km & 8km from the centre of the Sellafield Site could be the most likely areas to be directly affected during and following a radiation emergency, this area is referred to as the Detailed Emergency Planning Zone (DEPZ). To see its geographical extent please see map A (pg13) & C (pg20). • In addition, other assessments of the chemical hazards indicate that an area up to 2km from the centre of the Sellafield Site could be the most likely area to be directly affected during and following a chemical emergency, this area is referred to as the Inner Emergency Planning Zone (IEPZ). -

The Nuclear Decommissioning Authority Progress with Reducing Risk at Sellafield
A picture of the National Audit Office logo Report by the Comptroller and Auditor General The Nuclear Decommissioning Authority The Nuclear Decommissioning Authority: progress with reducing risk at Sellafield HC 1126 SESSION 2017–2019 20 JUNE 2018 Our vision is to help the nation spend wisely. Our public audit perspective helps Parliament hold government to account and improve public services. The National Audit Office scrutinises public spending for Parliament and is independent of government. The Comptroller and Auditor General (C&AG), Sir Amyas Morse KCB, is an Officer of the House of Commons and leads the NAO. The C&AG certifies the accounts of all government departments and many other public sector bodies. He has statutory authority to examine and report to Parliament on whether departments and the bodies they fund, nationally and locally, have used their resources efficiently, effectively, and with economy. The C&AG does this through a range of outputs including value-for-money reports on matters of public interest; investigations to establish the underlying facts in circumstances where concerns have been raised by others or observed through our wider work; landscape reviews to aid transparency; and good-practice guides. Our work ensures that those responsible for the use of public money are held to account and helps government to improve public services, leading to audited savings of £734 million in 2016. The Nuclear Decommissioning Authority The Nuclear Decommissioning Authority: progress with reducing risk at Sellafield Report by the Comptroller and Auditor General Ordered by the House of Commons to be printed on 18 June 2018 This report has been prepared under Section 6 of the National Audit Act 1983 for presentation to the House of Commons in accordance with Section 9 of the Act Sir Amyas Morse KCB Comptroller and Auditor General National Audit Office 15 June 2018 HC 1126 | £10.00 This report examines the Nuclear Decommissioning Authority’s progress with reducing risk and hazard at its largest and most hazardous site, Sellafield. -
