Shielding & Criticality Assessment Group
Over the past few years Nuclear Technologies has established
a team of highly skilled and experienced criticality, shielding
and radiological safety experts, with unrivalled expertise
in the design of new plants covering the whole of the nuclear
fuel cycle, as well as the operation and decommissioning
of nuclear plants. This has included the development of
criticality and shielding designs for major capital projects
such as the Sellafield THORP, the Sellafield MOX Plant
and numerous other facilities for the handling, treatment
and storage of nuclear materials. They have considerable
experience in dealing with the NII, and are fully cognisant
of the requirements of the NII Safety Assessment Principles
(SAPs) in addition to accepted criteria and substantiation
in modern standards safety cases.
Nuclear Technologies currently holds licenses for the industry
standard criticality and shielding codes MONK, MCNP and MICROSHIELD.
Our consultants are fully SQEP in the use of these codes,
as well as others that licensees may require, such as MCBEND
and RANKERN.
In addition, the team has extensive expertise in the requirements
of the IAEA Transport Regulations governing the off-site
transport of radioactive materials, through the criticality
and shielding assessment of new design and operational
transport packages. This has included close liaison with
the UK competent authority, the Department for Transport
(DfT).
We also have extensive experience in criticality emergency
planning arrangements, including the determination of dose
contours and CIDAS placement assessments.
The team has actively participated in the development of
national and international standards and criteria, through
organisations such as the OECD and IAEA, as well as the UK
Working Party on Criticality and the UK Shielding Forum.
