So far, experimental nuclear physics has been developped mainly by using accelerators. Nuclear structures and nuclear reaction mechanism have been extensively studied. The present URANUS puts emphasis on high sensitive detectors rather than accelerators. Thus it aims at exploring sensitivity(detector)frontiers rather than energy and intensity frontiers. URANUS opens new fields of particle and nuclear physics. They are conservation Laws, symmetry problems, fundamental interactions, neutrino physics, weak interactions, rate forbidden nuclear processes, rare(small)branches of nuclear reactions relevant to astrophysics, dark matters and their interaction with nucleons(quarks), and so on.Nuclear and particle physics by URANUS has been studied by several separated groups and summarized by mainly two workshop. In the first year the workshop on "Nuclear and Particle Physics Studied by URANUS" was held at Kamioka in Nov.15-16,1993. At the end of the second year, our work was summarized in the workshop on "Symmetries and Conservation Laws in Nuclear Quantum System" which was held at RCNP,Osaka University in March 8-9,1995.

迄今为止，实验核物理主要是利用加速器来发展的。核结构和核反应机理已被广泛研究。目前的天王星强调高灵敏度探测器而不是加速器。因此，它的目的是探索灵敏度（探测器）前沿而不是能量和强度前沿。天王星开辟了粒子和核物理的新领域。它们是守恒定律、对称问题、基本相互作用、中微子物理、弱相互作用、速率禁核过程、与天体物理学相关的核反应的稀有（小）分支、暗物质及其与核子（夸克）的相互作用等等。天王星的粒子物理学已经由几个不同的小组进行了研究，并主要由两个研讨会进行了总结。第一年，“天王星研究的核与粒子物理”研讨会于1993年11月15日至16日在神冈举行。第二年年底，我们的工作在1995年3月8-9日在大阪大学RCNP举行的“核量子系统中的对称性和守恒定律”研讨会上进行了总结。
