Front End Engineering


REACT is an independent organisation that is able to act in an impartial manner to facilitate valuable front end support such as option generation or design review and assessment. We can provide objective, auditable advice to our customers.

As an independent organisation REACT has no vested interest in the outcome of any option selection and assessment process. Our only concern is that it adds value to our customer’s project.

Here are some examples of the Front End Engineering tasks carried out by REACT:

  • Strategy and Engineering Option Studies
  • Application of Stage Gate Decision Processes for Design
  • Decommissioning Methodology Development (Dismantling and Waste Handling)
  • Waste Management Studies (Including Storage and Disposal)
  • Best Available Technique and Environmental Impact studies
  • Multi-Attribute Analysis
  • Plant Status Definition

REACT can help in the following ways:

  • Implementation Strategy
  • Readiness Reviews
  • Plant Modification Proposals
  • Safety Method Statements and Operator Instructions
  • Waste Characterisation Documentation
  • Radiation Dose Assessments and Dose Modelling
  • Shielding Calculations (Microshield)

N-Visage


Understanding the radiometric environment is often a key to success. REACT have extensive experience in radiation characterisation of nuclear facilities and have our own suite of products called N-Visage. Developed in house, in conjunction with our sister company Createc, the N-Visage™ output is a great consultancy tool and often provides vital intelligence for decommissioning or improvement projects.

Examples of REACT Radiometric Characterisation services include:

  • Development of Characterisation Strategies or Data Quality Objectives (DQO) Studies
  • Undertaking of radiation surveying including using the N-Visage™ Gamma Imager, a portable, remotely deployable device enabling the operator to “see” radiation
  • 3D modelling of activity distribution and radiation dose fields using N-Visage™ Predictive Gamma Modelling Software
  • Detailed scenario modelling, including modelling the effects of decontamination, radioactive decay or installation of shielding
  • Production of rendered video clips to illustrate the impact of radiometric characterisation on project strategy

Safety Support


The wide spectrum of work we undertake gives REACT a unique, balanced perspective on the requirements of a safety case. We recognise that a safety case must be operationally effective and consider various industrial situations, as well as radiological issues. We consistently work with our clients to identify safety improvements and provide solutions to safety issues to enable projects to proceed safely and without delay.

Examples of REACT Safety Support include:

  • Production of Safety Reports
  • Production of Safety Assessments
  • HAZOP
