yes, Nuclear fission as used in nuclear power plants produces radioactive waste with long half lives. However, this creates no problems. This wastes are either confined in the spent nuclear fuel (that is stored either in wet storage or in dry storage facilities) or stored as vitrified nuclear waste.
This is a trick question Nuclear waste should not be stored at all. But as we have some and need to store it, where is an important consideration. Transport is risky. Where you store it has to be able to handle it if it leaks for a million years or so, at least until its safe to handle. The US government has a facility that sounds good, A old salt mine that could hold the danger for a very long time. But is it really in a geologically stable place? Can it leak waste? Will there be an accident moving the waste? Should special storage be built where the waste is?

The nuclear wastes are currently placed in underground storage units (long tubes of radioactive waste materials) all over the country or all over the world.
Recycling nuclear fuel does not eliminate the need for long term storage of spent fuel. Uranium fuel is routinely refined and recycled, but the process is messy, expensive and itself creates nuclear waste. Some long lived isotopes of fission will always need disposal somewhere.
This is a disadvantage of nuclear power. But there are even more disadvantages for coal or natural gas power generation. The technology will come to figure out what to do the waste.
A biorepository is a long-term storage and conservation facility for biological specimens.
The longer the half-life of radioactive waste, the more consideration will have to be given to the design and construction of the container in which it is stored. This as well as where the container itself is stored. If we look at spent fuel from nuclear reactors, this highly radioactive and extremely long-lived radioactive waste will have to have a most substantial container. The storage container will have to last for many hundreds of years. Low level radioactive waste can be put up in less substantial containers and simply buried in an approved manner at an approved facility.
Two disadvantages of nuclear waste are: disposal of nuclear waste is very expensive and takes a long time, and nuclear waste is radioactive. The advantages are: nuclear power plants are usually built on a coast, so the risk of contaminating drinking water is low; nuclear waste does not emit carbon into the air.
Nuclear wastes are sometimes said to be a problem too difficult to solve because the waste stays radioactive for so long. The only thing that gets rid of nuclear waste is time.
The biggest issue associated with nuclear power is determining what can be done with the radioactive waste.
