Recent progress on ultra-intense short-pulse lasers enables us to have highly intense bursts energetic radiations (electrons, ions, and X-rays) from relativistic laser plasmas. The radiations are applicable to inducing nuclear excitations and nuclear reactions, and it is expected to open the new field of "Laser Nuclear Engineering". Ultra-intense short-pulse lasers, relativistic laser plasmas, and energetic radiations are reviewed, and some future applications are introduced.
