Could be intense heat rays loaded with infrared light coming off the oddly shaped rods. Pink has always been an odd color in nature. I have seen pinks and purples that were close to blue light. Violet for example looks a little blue pink at times. Probably just camera/tv problems.

If its Cherenkov light emmission we in deep do-do

From Wikipedia.

Cherenkov radiation is used to detect high-energy charged particles. In pool-type nuclear reactors, the intensity of Cherenkov radiation is related to the frequency of the fission events that produce high-energy electrons, and hence is a measure of the intensity of the reaction. Cherenkov radiation is also used to characterize the remaining radioactivity of spent fuel rods.

Ummm, yeah.

Here, read up before promoting panic, mmmkay?
