verification tests. 2.11 Security requirements should be identified and taken into account in addition to safety considerations. Conflicting requirements should be identified and resolved. According to those requirements, on-site arrangements should be implemented, including physical protection against sabotage in use and storage of items important to safety. 2.12 For sites with existing nuclear installations, emergency preparedness should take account the followings: - The average and peak employment at the site throughout the construction or modification project; - Training of construction site personnel; - Provision of additional alarms all personnel at the site; and, - The various phases of construction and commissioning with their inherent risks. 2.13 The regulatory body should ensure that the licensee(s) 3 carries out a risk and threat assessment to determine the possible risks of the construction site to the existing facilities and the effect of existing facilities on the construction site. These risks depend on the site and construction method which therefore should be analysed for each individual site. Possible risks are caused by, but not limited to, dredging, quarrying, excavation, blasting, piling, dust, transportation and lifting. Preventive measures should be taken to manage the construction related risk. Further guidance on interaction with existing facilities is provided in paras 5.42 – 5.44. 3 In some cases multiple licensees on the same or nearby site may exist 8
2.14 Installations which handle, process or store potentially hazardous materials such as explosive, flammable, corrosive, toxic or radioactive materials should be identified. The maximum amount of hazardous material present at any given time and the process in which it is used should be taken into consideration. Pipelines for hazardous materials should be included in the category of items to be identified. Other sources to be considered are construction yards, mines and quarries which use and store explosives and which may cause the temporary damming of water courses, with possible subsequent flooding or collapse of ground at the site. For other potential sources of human induced external events, refer to paras 3.9 – 3.11 of Ref. [14] for more details. 2.15 Environmental monitoring and protection measures at the site should be in place to ensure adequate mitigation of potential environmental effects related to construction activities. 2.16 Necessary fire protection measures at the construction site should be available until final plant fire detection, protection, and suppression systems are installed and operational. Details of these measures should be included in the emergency planning arrangements. 2.17 The security measures that describe actions taken during construction should consider, detect, and deter conditions that would impair the capabilities of security- and items to perform their intended safety functions, where those conditions are not otherwise detected by engineering and performance barriers to ensure that items are installed and tested as designed. Security measures employed should consider control of personnel, material, and vehicles; random patrols/inspections as defined in site security procedures; and screening (pre-employment screening and gate clearance) for access to security and safety controlled areas. As a minimum, security measures within and around the site should include physical barriers, posting, surveillance and monitoring capability, uniformed security personnel, 9
