Cóip statach de shonraí a easpórtáiltear ó IATE ó am go chéile atá sa chnuasach seo. Níor cheart glacadh leis gurb ionann i gcónaí an t-eolas a thugtar faoi iontráil anseo agus a bhfuil sa leagan reatha den iontráil ar IATE. Is féidir an leagan reatha sin a cheadú ach cliceáil ar an nasc atá ar thaobh na láimhe deise ag barr gach iontrála. Breis eolais »

    Sainmhíniú water in which the hydrogen in the molecules is partly or wholly replaced by the isotope deuterium, used especially as a moderator in nuclear reactors Tagairt Oxford Dictionaries > British & World English > heavy water [2.10.2015]
    Nóta Because of the very low neutron absorption cross-section of deuterium, heavy water makes an excellent moderator and is used in, for example, CANDU and SGHWR nuclear reactors. It is present in ordinary water at one part in about 5000.
