• 2008:48E Review Statement and Evaluation of the Swedish Nuclear Fuel and Waste Management Co´s (SKB) RD&D Programme 2007

  The review of the RD&D Programmes (Research, Development, Demonstration) prepared by the Swedish Nuclear Fuel and Waste Management Co (SKB) is a recurrent task that the Swedish Nuclear Power Inspectorate (SKI) must carry out as a regulatory authority with the support of reviewing bodies of which the most important is the Swedish Radiation Protection Authority (SSI). The review statement for...

• 2008:47 Selected Models for Key Processes in a Nuclear Waste Repository

  The conceptual design of the disposal of spent nuclear fuel in Sweden is based on a multibarrier system. In the KBS-3 concept, the bentonite buffer is a barrier with the primary purpose of surrounding and protecting the canister. The bentonite buffer is expected to prevent or minimise the water exchange with the surrounding rock and protect the canister against mechanical damages caused by...

• 2008:49 En studie av olycksutredningsmetoders utveckling: En sammanställning över “State-of-the-Art”

  Projektets syfte var att kartlägga de huvudsakliga olycksutredningsmetoder som utvecklats sedan början av 1990-talet. Motivationen är den ökande frekvensen av olyckor som sätter sig upp mot förklaringar i enkla termer, så som orsak-verkanskedjor eller mänskliga fel. Medan komplexiteten hos sociotekniska system är stadigt ökande i alla industriella...

• 2008:34 Utformning av larmsystem i svenska kärnkraftverk

  Det pågår flera stora moderniseringsprojekt inom den svenska kärnkraftindustrin. En del i dessa projekt består av att man helt eller delvis byter ut analoga informations- och manöversystem i kontrollrummen till digitala vilket förändrar larmsystemen. Digitala larmsystem har en mängd fördelar men kan också medföra risker och negativ säkerhetspåverkan.

• 2008:38 Methodology for description and evaluation of cost profiles and cost structure during transitions period

  A demanding task for our generation is to assure the appropriate financial resources are invested in the Swedish Nuclear Waste Fund. This will enable future generations to execute the decommissioning and dismantling of nuclear power reactors and other nuclear facilities in a prudent manner. The main aim is to fulfil the demands of environmental and health codes in a pan-European context...

• 2008:50 Study on Developments in Accident Investigation Methods: A Survey of the “State-of-the-Art”

  The objective of this project was to survey the main accident investigation methods that have been developed since the early or mid-1990s. The motivation was the increasing frequency of accidents that defy explanations in simple terms, for instance cause-effect chains or “human error”. Whereas the complexity of socio-technical systems is steadily growing across all industrial domains,...

• 2008:29e Safety and Radiation Protection at Swedish Nuclear Power Plants 2007

  The safety level of the plants is maintained at an acceptable level. SKI has in its regulatory supervision not found any known deficiencies in the barriers which could result in release of radioactive substances in excess of the permitted levels. SKI considers that improvements have been implemented during the year in the management, control and following up of safety work at the plants. In...

• 2008:29 Säkerhets- och strålskyddsläget vid de svenska kärnkraftverken 2007

  Säkerheten vid de svenska reaktorerna upprätthålls på en godtagbar nivå. Det har vid tillsynen inte uppdagats några kända brister i barriärerna som medför utsläpp av radioaktiva ämnen vilka överstiger gällande gränser. SKI bedömer att förbättringar i ledning, styrning och uppföljning av säkerhetsarbetet...

• 2008:05 ULiAS 4 – Experimental validation of asoftware that models ultrasonic wavepropagation through an anisotropic weld

  New and stronger demands on reliability of used NDE/ NDT procedures and methods have evolved in Europe during the last decade. In order to elaborate these procedures, efforts have to be taken towards the development of mathematical models of applied NDT methods. Modelling of ultrasonic non-destructive testing is useful for a number of reasons, e.g. physical understanding, parametric studies,...

• SKI Report 2008:01 Reliability Data for piping Components in Nordic Nuclear Poer Plants "R-Book" Project Phase 1

  SKI Report 2008:01 - “Reliability Data for Piping Components in Nordic Nuclear Power Plants - R-Book Project Phase I” – is a planning document for a new R&D project to develop a piping component reliability parameter handbook for use in probabilistic safety assessment (PSA) and related activities. Included in this handbook will be pipe leak failure rates and rupture frequencies that are...
