¹ The fol­low­ing modi­fic­a­tions are gen­er­ally re­garded as modi­fic­a­tions that do not de­vi­ate sig­ni­fic­antly from the re­spect­ive li­cence but which re­quire a per­mit in ac­cord­ance with Art­icle 65, para­graph 3 of the Nuc­le­ar En­ergy Act:

a.

modi­fic­a­tions to struc­tures, sys­tems and com­pon­ents sub­ject to safety or se­cur­ity clas­si­fic­a­tion and to equip­ment rel­ev­ant to safety or se­cur­ity, provid­ing the ex­ist­ing safety or se­cur­ity func­tions are main­tained or im­proved;

b.

the fol­low­ing modi­fic­a­tions to the re­act­or core:

1.

modi­fic­a­tions to the load­ing of the re­act­or core with fuel ele­ments as part of the re­fuel­ling pro­ced­ure,

2.

modi­fic­a­tions to and re­pair of fuel ele­ments and con­trol rods,

3.

in­crease of per­miss­ible burn-up,

4.

modi­fic­a­tion to safety as­sess­ment meth­ods,

5.

modi­fic­a­tion of safety cri­ter­ia,

6.

in­crease of the pro­por­tion of urani­um-plutoni­um-mixed-ox­ide fuel ele­ments in re­act­or core up to a max­im­um of 50 per­cent;

c.

changes in the con­tent of the fol­low­ing doc­u­ments:

1.

the power plant or op­er­at­ing reg­u­la­tions,

2.

the emer­gency pre­pared­ness reg­u­la­tions,

3.

the ra­di­ation pro­tec­tion reg­u­la­tions,

4.

the tech­nic­al spe­cific­a­tions,

5.

the reg­u­la­tions and in­struc­tions re­lat­ing to se­cur­ity.

² To ob­tain the ne­ces­sary per­mit in ac­cord­ance with para­graph 1 let­ters a and b, the li­cence hold­er must sub­mit all the doc­u­ment­a­tion ne­ces­sary for the as­sess­ment as afore­men­tioned in An­nex 4.

³ To ob­tain the ne­ces­sary per­mit in ac­cord­ance with para­graph 1 let­ter c, the li­cence hold­er must sub­mit all the re­quired doc­u­ment­a­tion to­geth­er with an ex­plan­a­tion of the reas­on for the changes.

⁴ For modi­fic­a­tions of tech­nic­al spe­cific­a­tions, the li­cence hold­er must also ex­plain the meth­od and tech­nic­al cri­ter­ia that have been used for as­sess­ing the im­pacts of the modi­fic­a­tions on the safety of the in­stall­a­tion.

⁵ EN­SI shall reg­u­late the type, con­tent, present­a­tion and num­ber of re­quired ap­plic­a­tion doc­u­ments in guidelines.⁵⁰
