A worldwide industry. One single dashboard.

The SMR Dashboard of the OECD Nuclear Energy Agency tracks the world’s small modular reactors. With Niji, Witify and its Kashika Studio division designed the screens; other teams built it.

01 The numbers

Four figures, counted on the design file

What we designed, counted on the file itself. None of these numbers describes the dashboard that other teams built.

  • 6

    screens designed, under three tabs Global picture, assessments, pipeline.

  • 10

    types of visual, from the map to the sunburst Bars, scatter plots, a map, a table of scores.

  • 6

    shades on a single progress scale Shared by seven of the ten visual types and by two of the home-screen counts.

  • 7

    editions side by side in a reactor’s history Two yearly editions, then five updates the design allows for.

Counted on the design file on 13 November 2026.

02 The path

From the whole field to a single reactor, in four screens

The design reads from the general to the particular: the state of the field, the list of reactors, the profile of one of them, then the road they all travel.

01 Overview

Four numbers, then the road to deployment

The home screen opens on four numbers: designs identified, those on hold, those moving forward without an assessment, those assessed. Below, an arrow sorts the projects into six stages, from concept to operation.

02 The list

One reactor per row, six criteria as strips

Each design fits on one row, its six criteria scored on the same strip of six cells: the fuller and darker it is, the further along the project. A red arrow marks what has risen since the previous edition.

03 The profile

A sunburst, and the organizations around it

The profile opens on a six-sector sunburst, one sector per criterion, each filled up to its score. Beside it, a map and a list place the project’s organizations, from the regulator to the suppliers.

04 The pipeline

From a pipeline stage to the reactors in it

With changes shown, a dotted line recalls each stage’s height at the previous edition and a chevron says whether it went up or down. For a stage under the pointer, the design opens the list of its reactors, each tied to its profile.

03 The scale

Six shades to read everything, edition after edition

A grey for missing information, then five shades from pale yellow to dark green: the same scale colours the pipeline, the map, the strips and the sunburst. On the profile it becomes a history, one column per edition.

04 The views

Where, how hot, by family: three more views

The same reactor designs, seen another way: where they are sited, what heat they supply, how far each family has come.

Sites

A map for where, a ranking for how many

Each dot is a site, coloured by how far along it is. On the right, countries are ranked by number of sites.

Heat

Which reactor for which industrial use

Reactors by family and outlet temperature, set against the needs of industry, from paper to steel.

Families

The same pipeline, one family at a time

The design plans this pipeline for each of the six criteria; here, licensing, by reactor family.

05 Our choices

Three choices so a dashboard needs no manual

Three design decisions mattered more than the others. For each one: the risk to avoid, what we designed, and the intended gain.

  1. Open on the state of the field, not on a map.

    The risk
    A map on the home page says where the projects are, not how far along they are. A reader in a hurry leaves without an answer.
    Our choice
    Four numbers and the pipeline open the screen; the map comes right below, with its filters.
    The gain
    The state of the field is clear on one screen, before the first click.

  2. Show what moved, the same way everywhere.

    The risk
    Updates nobody notices: a returning reader cannot see what has changed since their last visit.
    Our choice
    One switch, and the same marks from screen to screen: a red arrow on a score that rose, a dotted line for a stage’s former height, a ring around a newcomer.
    The gain
    What has changed stands out without searching.

  3. Standard charts first, custom ones as a last resort.

    The risk
    Designing charts the build tool cannot produce: they would stay on the drawing board, or cost a lot to maintain.
    Our choice
    Standard maps, bars and scatter plots wherever they are enough; custom work is kept to a few forms, such as the arrow pipeline, reused from one criterion to the next.
    The gain
    A design meant to be built with common charts, then kept up to date by the agency’s team.

06 The mandate

What we delivered, and what others built

A design mandate, carried out with the firm Niji: Kashika Studio’s design method, then the screens. Building the dashboard, on a business intelligence tool, was the work of other teams.
Role
Screen design, Kashika Studio, Witify’s data division
Method
Data, readers, concepts, screens, what to show, to whom, then how
Design tool
Figma, one file, six screens

Other teams, on a business intelligence tool

Key milestones

  1. January 2025 Design mandate The design method and the screens, entrusted to Kashika Studio by Niji.
  2. Early February 2025 First screens A first version of the screens.
  3. Mid-February 2025 Readers workshop Who will read the dashboard, and with what question: a workshop led by Niji with the agency’s team.
  4. Late February 2025 Revised screens The revised version of the screens, with the six-shade progress scale.
