CNNC un­veils key safety tech­nol­ogy

China Daily - - BUSINESS - By ZHENG XIN [email protected]­

China Na­tional Nu­clear Corp, the State-owned nu­clear power com­pany, re­leased its do­mes­ti­cally-de­vel­oped high-safety nu­clear power plant dis­trib­uted con­trol sys­tem plat­form on Thurs­day.

Known as the cen­tral ner­vous sys­tem of nu­clear power plants, the nu­clear ad­vanced safety in­stru­ment and con­trol plat­form, also called the Longlin sys­tem, plays an im­por­tant role in en­sur­ing nu­clear pro­jects’ safety and sta­bil­ity and en­ables China to have a DCS with com­plete in­de­pen­dent in­tel­lec­tual prop­erty rights, said the com­pany.

Some of the key stan­dards are in ac­cor­dance with the in­ter­na­tional level, it said, while it will also help boost China’s nu­clear tech­nol­ogy ex­ports, it said.

Only a hand­ful of de­vel­oped coun­tries have mas­tered the tech­nol­ogy of the nu­clear-grade DCS plat­form, which is crit­i­cal for the safe shut­down and ac­ci­dent mit­i­ga­tion for re­ac­tors.

An­a­lysts be­lieve as the core tech­nol­ogy of the sys­tems is one of the key com­po­nents of a nu­clear power sta­tion, China must con­duct orig­i­nal in­no­va­tion.

It is be­lieved the coun­try will step up nu­clear de­vel­op­ment with the im­ple­men­ta­tion of the Longlin sys­tem, said Ye Qizhen, a mem­ber of the Chi­nese Academy of En­gi­neer­ing and also an ex­pert on nu­clear re­ac­tors and nu­clear-power en­gi­neer­ing.

Ac­cord­ing to CNNC, all of the de­sign, ver­i­fi­ca­tion and test­ing of the pro­gram is in ac­cor­dance with the most ad­vanced and strictest stan­dards world­wide, while the sys­tem also uses ad­vanced in­for­ma­tion se­cu­rity tech­nol­ogy.

The Longlin sys­tem is a re­sult of the com­pany’s more than 60 years of ex­pe­ri­ence in in­te­grat­ing nu­clear power en­gi­neer­ing de­sign, the re­search and de­vel­op­ment of the dig­i­tal in­stru­ment con­trol equip­ment and equip­ment man­u­fac­tur­ing and sup­ply.

The sys­tem could be ap­plied in nu­clear power plants, re­search re­ac­tors and small re­ac­tors, it said.

Yu Jian­feng, CNNC’s chair­man, said ear­lier that de­vel­op­ment of the nu­clear in­dus­try over the past 60 years has proved that nu­clear science and tech­nol­ogy is strate­gi­cally im­por­tant. China must in­sist on in­de­pen­dent in­no­va­tion.

The com­pany said it would pay a great deal of at­ten­tion to the work­ing con­di­tions of sci­en­tists, an im­por­tant fac­tor in im­prov­ing the com­pany’s core com­pet­i­tive­ness.

“We will en­able sci­en­tists un­der­tak­ing ma­jor mil­i­tary pro­jects and sci­en­tific and tech­no­log­i­cal in­no­va­tions to re­ceive high salaries, and stim­u­late the cre­ativ­ity of tal­ent to the great­est ex­tent,” he said.
