About Forsmark
• One of the largest power plants in Sweden with three boiling water nuclear
reactors
• 20–25 billion kilowatt hours of electricity generated in a normal year
• This is approx. one sixth of Sweden's total electrical energy consumption
• Situated on the east coast of Sweden, two hours northeast of Stockholm

About the Industry
• The safety demands on nuclear power plants are very strict
• Well-defined and highly regulated processes ensure smooth, safe
and efficient daily operations
• Safety culture and safety work represent important aspects of staff
training
• Experiences are logged and processed in an orderly fashion to
facilitate learning from all types of experiences
• Maintenance work is thoroughly planned
• Pre-job briefings and post-job debriefings are common practice
before and after maintenance tasks are carried out

WHAT – The Business Goals
Push production costs down
Provide engineers with the information they need to plan daily maintenance tasks better and thus
avoid costly delays
Promote high availability*
Provide engineers with the information they need to plan the yearly overhaul and refueling properly to
avoid schedule overrun and extra days off the grid
Decrease the number of work place injuries
Provide the maintenance team with the information they need in pre-job briefings so work tasks are
clear and can be carried out safely
Onboard new employees quickly
Provide tools by which the new generation of co-workers will be able to learn the trade quickly
Learn from the knowledge and experiences of others
Provide tools that will help spread knowledge and good practices among co-workers
*) The availability factor of a power plant is the amount of time that it is able to produce electricity over a certain period, divided by the amount
of the time in the period. - Wikipedia

WHY – The Business Drivers
Electricity prices in the Nordics have been low since 2012
This puts pressure on power companies to cut and keep production costs low.
Every extra day “off the grid” during refueling means less income
Yearly overhaul and refueling requires downtime, but availability can be optimized with better planning.
Nobody should get injured at work
By proper processes and tools, the number of serious injuries within plant maintenance can be kept at
zero and the need for redoing less safe work tasks (like re-examining a valve in a room with elevated
radiation levels) can be avoided.
The quicker you learn, the sooner you are productive
The nuclear power industry in Sweden is in the middle of a generation shift.

HOW – The Solution
Use search as a platform in which information is aggregated and from
which information can be retrieved to be presented where and when
needed.
We started our search journey in 2009 and switched to Elasticsearch
as the core in 2014.

HOW – Guiding Principles
1. The information must come to where the user is – and not the
other way around
2. Rather present highly accurate information than a bloated result
set of information of various degrees of importance
3. Make full use of the well-organized information structure at
Forsmark including common metadata
4. Use open source technology unless commercial vendors provide
significant benefit
