Sparky—yes. Look
here on this website for a list of the solar abundance of the elements in the periodic table. Uranium is listed, and it is
not the least element listed in terms of abundance on the Sun. {Its dot on the graph is higher, vertically, than several lighter elements, and a lot of heavy elements beyond iron like gold, mercury thorium, rhenium etc are definitely present. You can drag the vertical cursor onto each element and read off its relative abundance in the makeup of the Sun. This link is a useful website on the periodic table, in general, and you can organize or plot the elements according to a number of their different characteristics, from atomic number to density to ionization energy, etc.
The EU's take on the elemental abundance is that fusion [of lighter elements into heavier elements] can and does occur in the solar atmosphere where conditions are extreme enough to facilitate that process. We cannot observe whether or not the contemporary viewpoint, or dogma, as some prefer, about the Sun's interior is correct, but there are many plausible arguments against the Sun's being powered internally. Of course, given the lack of observational evidence, the jury is out on that, and conjecture and ideas abound.
However, stellar fusion itself apparently cannot convert lighter elements into anything heavier than iron, so the popular answer by scientists to the question, "where do elements heavier than iron come from?" is that only the conditions present in a supernova can make those heavier elements, like nickel and cobalt signatures, and gold and tantalum, tungsten and iridium, and many others. Or else, that the dusty "cloud" which contracted to create the proto-Sun and "spark its fusion engine" already contained fractional amounts of elements heavier than iron as detritus ejected over time from supernova explosions.
But what if the "anomalously" high temperatures in the solar corona were as conducive to fusion of elements beyond iron as those in a supernova? And what if the dusty plasma entrained and compressed by a cosmically scaled Birkeland current pinch had a sprinkling of heavier element in line with the consensus view, and when the pinching currents created the plasmoid that became the Sun, it already had some measure of elements heavier than iron, and possibly even made more? There's no reason to limit the production of heavy elements to supernovas, though, in the plasma universe. The energy density buildups possible in a high-velocity, high amperage pinch, with large double layers accelerating charged particles to teraWatt power levels, could indeed rival even a supernova release, until things settle down to a more stable mode.
