I. Health

Happsy Line: Psychological support scheme for INSTN students

In this complex and unprecedented health context, the INSTN set up in January 2021 the Happsy Line initiative for its students.

Funded by the CVEC (Student Life and Campus Contribution) with support from the Versailles Crous, the objective of Happsy Line  is to help students cope with any worries or concerns they may be going through and which may be preventing them from moving forward in their personal lives and studies.

II. Transportation

Cadarache training site

  • CEA personnel coaches

Thirty regular coach lines (free of charge) provide collective transportation and serve most of the districts in the region. The CEA coaches arrive at and depart from the CEA bus station. 

In the morning, the personnel is dropped off before 8.00 am. In the evening, the 30 lines leave at 16.30 pm.

Shuttles connect the CEA bus station and the INSTN, via le Hameau (INSTN Cadarache student residence).

You will be informed of the line number, timetables and pick-up points by your training assistant at the start of the year, on an as-needed basis.

The CEA buses arrive at and depart from the CEA bus station (close to the east entrance), a 5-8 minute walk from the INSTN. The bus station is outside the CEA site.

You will be informed of the line numbers, timetables and pick-up points by your training assistant at the start of the year.

  • Inter-company buses

The buses depart at regular intervals from Porte d'Orléans and the bus stop is located close to the INSTN entrance (CEA East gate stop).

To be able to take CEA buses, you will need to show identity papers and your green badge, which will be handed out at the start of the year by your training assistant.

During their studies at the INSTN, students can access the CEA personnel cafetarias (except Cherbourg, which is not on a CEA center) where they benefit from a special price (2021 tariff: about € 2.48; minimum cost of a meal, once per day).

You can access the CEA cafetarias by means of a canteen card or the CEA access badge, which will be handed to you after your arrival.

The restaurant card and/or access badge are named. At Cherbourg, you will be able to use the university cafetaria la Passerelle.
