[en] The Instituto Nacional de Investigaciones Nucleares (ININ) participated in an international tender published by the Colombian Geological Service for the modernization of the Nuclear Reactor Control Console Ian-R1, the participating institutions were: General Atomics (USA), INVAP (Argentina) and ININ (Mexico). The proposal made by the ININ had an important characteristic, the independence of the manufacturer, since it was a project based on modular elements. One of the elements was the Human-Machine Interface (HMI), where the development was proposed under the Free Software (Gnu-GLP) scheme. Java was the programming language on which the HMI was developed to operate the nuclear reactor in Bogota, Colombia. The instrumentation that allows the interaction with the sensors and/or actuators is based on the use of PLC's (programmable logic controllers) with which the computers of the HMI communicate through a local network using the Mod bus protocol over Ethernet.

[en] In this article is documented the development of a system of radiological and environmental monitoring, with the purpose of having a better control of the different interests areas for the Radiological Protection Department, in such a way that represents a support to maintain the radiological safety and in a contingency case to activate the Radiological Emergency Plan of the Institute, being aided of the radiological and environmental information provided by this monitoring system. To achieve this, firstly enables the communication through the net of institutional data Ethernet Tcp/I p to the different systems as Meteorological Station, Reactor, Radioisotopes Production Plant, Access Portal and Perimetric Monitoring, later on was required the information to each one of them through two servers and this way to carry out the visualization and data storage in a remote way, the use of two serves offers redundancy to the system.
