(a) The Vessel shall not be obliged to proceed or required to continue to or through or remain at, any port, place, area or zone, or any waterway or canal (hereinafter “Area”) which may expose the Vessel, her cargo, crew or other persons on board the Vessel to danger from levels of ionizing radiations from or contamination by radioactivity from any nuclear fuel, nuclear waste or from the combustion of nuclear fuel, or the radioactive, toxic, explosive or other hazardous or contaminating properties of any nuclear installation, reactor or other nuclear assembly or component thereof (hereinafter “Radioactivity”) determined by a competent national or international authority (including but not limited to the International Atomic Energy Authority and/or the World Health Organization) to be harmful to human health.
(b) If in accordance with sub‐clause (a) the Owners decide that the Vessel shall not proceed or continue to or through or remain in the Area they must immediately inform the Charterers. The Charterers shall be obliged to issue alternative voyage orders and shall indemnify the Owners for any claims from holders of the Bills of Lading caused by waiting for such orders and/or the performance of an alternative voyage. Any time lost as a result of waiting for or complying with such orders shall not be considered off‐hire.
(c) The Vessel shall have liberty to comply with all orders, directions, recommendations or advice of competent authorities referred to in Sub‐clause (a) and/or the Flag State of the Vessel in respect of arrival, routes, ports of call, destinations, discharge of cargo, delivery, or in any other way whatsoever.
(d) The Charterers warrant that they shall not load cargoes and/or empty containers and/or supply bunkers that have levels of Radioactivity in excess of normal radiation levels for these items. The Owners, at their discretion, may arrange for a radioactive survey by an independent qualified surveyor. If the level of Radioactivity in the cargoes, empty containers and/or bunkers is determined by the surveyor to exceed normal levels for these items, the Owners shall have the right to refuse to load such cargoes, empty containers and/or bunkers, and the cost, expense and time for the survey shall be borne by the Charterers. If radiation levels are found by the surveyor to be within normal levels for these items, the cost, expense and time for the survey shall be borne by the Owners.
(e) Any delays arising out of measures taken by port authorities to screen the Vessel for radiation either in the countries affected by Radioactivity or at subsequent ports of call shall be for the Charterers’ account. Any time lost as a result of complying with such screening shall not be considered off‐hire. If the Vessel’s ballast water is found to be contaminated by Radioactivity above normal levels then the cost of the safe disposal of the contaminated ballast water, decontamination of the Vessel’s ballast water tanks and any delays arising out of the contamination to the Vessel shall be borne by the Charterers.
(f) If in compliance with this Clause anything is done or not done, such shall not be deemed a deviation, but shall be considered as due fulfilment of this Charter Party. In the event of a conflict between the provisions of this Clause and any implied or express provision of the Charter Party, this Clause shall prevail to the extent of such conflict, but no further.
