The present specification provides an organoluminescent device including a capping layer on one surface of an electrode, wherein the capping layer includes a compound represented by Chemical Formula 1: 

Organic electroluminescent element

Provided is a modular reactor head area assembly. The modular reactor head area assembly is installed on a reactor head, and includes: a seismic support structure that performs functions of lifting, moving and reinstallation of the reactor head and control rod driving apparatuses, cooling of the control rod driving apparatuses, shielding of missile parts, and supporting with respect to a seismic load, and disperses a load applied to the control rod driving apparatuses; an upper module that is an assembly of components located at an upper portion of the seismic support structure for the control rod driving apparatuses; and a lower module that is an assembly of components located at a lower portion of the seismic support structure for the control rod driving apparatuses. The upper module and the lower module aredetachably coupled to each other so that maintenance of the control rod driving apparatus can be performed easily.
