Nuclear Incidents: Overview

Newrisk Limited is available to advise organisations and governments on nuclear incidents, including the prevention and response to nuclear incidents. Newrisk Limited has previously advised on issues related to the Japanese Fukushima Daiichi nuclear plant, as well as nuclear issues affecting Pakistan and Iran.

Newrisk Limited and its principal adviser, Dr Leivesley, have experience of advising organisations and governments on nuclear incidents, including the protection of governmental functions and the general public in the event of a nuclear event and radiological consequences. Dr Leivesley trained as a scientific adviser with the Home Office and during that time completed a specialist course in Advanced Radiobiology. Subsequently, Dr Leivesley was contracted to the Scientific Research and Development Branch of the Home Office.

Within her role as a Scientific Adviser, Dr Leivesley exercised with local authorities and other government organisations on the protection of the country under extreme threat conditions. This included numerous exercises on the evacuation of London and the minimisation of extreme consequences of threats on the population.

Newrisk Limited has advised corporations and undertaken media commentary during the immediate crisis of the radiological contamination from the Fukushima Daiichi nuclear plant, following the 11th March 2011 Japanese earthquake and tsunami which disabled the Fukushima Daiichi nuclear reactors' cooling systems (details of Newrisk Limited's experience in relation to Fukushima, is available by following this link). Previously, Dr Leivesley also reviewed the Chernobyl incident and Three Mile Island incident for organisations in the UK and abroad.

Newrisk Limited and its principal adviser, Dr Leivesley, have previously provided media commentary, lectures, conference papers, workshops and publications on nuclear incidents. Further information on these lectures, conference papers, workshops, publications and commentary is available by following this link.

Prepare for the unexpected. New forms of attack will be unexpected in time, tactics and consequences and may include kinetic attacks on undersea cables and space infrastructure. 

Questions to Consider:
Does the organisation have a capacity to fast switch to other cloud, in-house server or hot site operations to limit recovery time? Are there diagnostics for sensors and control systems and the interface with operations?  Could a global security crisis in the South and East China Seas and flash points elsewhere (including Europe) target an organisation’s upstream cyber providers?  Other resilience tasks to check are:

  • - Competent external recovery services;
  • - Internal policies for real time back- up systems unconnected to live operations;
  • - Financial resources for full re-build after ransomware;
  • - Internal policies to avert ransomware payments; 
  • - Cooperative recovery planning with industry peers;
  • - Regular modular and  whole of organisation exercises;
- Multiple scenario tests for strength of preparedness.

 Nations signalling intent of conflict.
 Energy regeneration challenges.

Nuclear conflict and radiation incidents are a high risk for some regions.  Nations are engaging in
‘signalling’ capability of weapons and intent. The most frequent signals are coming from China in
relation to Taiwan; the USA in relation to freedom of navigation in the South China Sea; Russia in
sending Zircon hypersonic missiles onto naval voyages into the Atlantic, movement of nuclear
weapons to Belarus and threats to Ukraine; North Korea in frequency of missile tests including
submarine launched missiles and drones; and Iran’s apparent nuclear enrichment found to be at
84% purity.

Planning for Energy Regeneration Post Nuclear Conflict:
1. Hardened energy infrastructure;
2. Academic and Industry collaborative Programmes;
3. Small Modular Reactors built underground;
4. Supplemental critical control system separated from IOT; and
5. Energy planning for rail transportation of populations.
