attentionImportant reminder about User ID card

Updated on 2014/06/16@

There was an incident a user did not make sure that his/her J-PARC User ID was fully dropped into the return box. The strap was hanging outside of the box so that someone could pick it up and could possibly make used of it.

Please be aware that J-PARC User ID card would enable people getting into the JAEA/J-PARC site where significant amount of radioactive materials are stored. This kind of incident makes our credibility for nuclear security questionable.

Please take a moment to make sure that your ID card is fully dropped into the return box. We should also remind you that you are required to display the ID card all the time when you are inside of J-PARC/JAEA site. When you are outside of the site, you must make sure that the ID card is stored in a safe place.

Your understanding and your cooperation will be much appreciated. Thank you.

Strengthening of the access control to J-PARC/JAEA

Updated on 2013/3/14

Due to a law change regarding places that keep radioactive materials, J-PARC/JAEA security check at the entrance gates will be significantly tightened. 
Everyone entering the JAEA/J-PARC site will be checked to see if the person has a valid ID card (J-PARC User ID / KEK ID / JAEA ID) with a picture to enter the site. 
This includes everyone in a car (or bus) with a valid sticker (Viechle permission pass).

As this would cause a big traffic jam at the entrance gates, between March 15 and 28, JAEA is planning a dry run to find a way to cope with the situation when it will become effective on March 29, 2013. 
Please make sure that you always carry a valid ID card(J-PARC User ID / KEK ID / JAEA ID) to be in J-PARC/JAEA site and follow the direction of guards when you enter. 
When you enter by car, you may be directed to a parking place and then get the ID checked. 

Be aware that this dry run will be done in a special way between 8:00 and 9:00 in the morning of weekdays when traffic will be the heaviest. 
(There could be changes after the March 29th if present plan would be found impractical during the dry run.)
