[en] The role of the regulator to progressively assure safety in order to arrive at the licensing stage without significant safety related issues is presented. Mexico considers such a role as a responsibility, especially when dealing with a utility that is building its first reactor. This concept may appear novel, however, it is presented here as inherent in any regulatory scheme. Based on the above mentioned considerations, the regulatory body of Mexico is prepared to provide assurance that during the transition period from construction to operation of the Laguna Verde facility, all possibile errors and defects are detected and corrected. In this manner Mexico will build its nuclear plant as safe as possible

[en] This work intends to analyze 5 incidents at the Green Lagoon NPP and to characterize their relative importance in the risk level obtained in the APS original and thus to help to evaluate the specific operational and design problems of the plant according to the methodology proposed by the IAEA

[en] The main features of the unit 1 of the Laguna Verde Power Plant is presented as well as the phases of the start-up process. The process includes various steps and tests up to start the commercial operation. (author)

[en] In response to generic letter GL 88-20, Comision Federal de Electricidad and Instituto de Investigaciones Electricas have jointly developed the individual plant examination (IPE) for the Laguna Verde nuclear power station unit I (LVNPS). This plant is a 675-MW(electric) boiling water reactor (BWR/5) with a reinforced concrete Mark-II containment. The approach used to fulfill the IPE requirements was to make a level-1 probabilistic risk assessment (IPE level 1) plus a containment performance analysis including the behavior and release of the fission products to the environment (IPE level 2). This paper describes the level-2 portion of the LVNPS IPE, paying special attention to both some improvements to the traditional analytical methods and to the main results

[en] The present work describes the event occurred at the Laguna Verde nuclear power plants Unit 1 during its fourth cycle ensembles; the first failure, by means of a test of power suppression, and the second one, during the sipping accomplished in the four refuelling of the unit. Also it describes the re-evaluation of the event accomplished by the licenser, the manufacturer and the Mexican agency

[en] The paper addresses the regulatory framework established for the design, construction and operation of the NPP. The regulatory bases of the inspection program are mentioned.A summary of the inspection and reviewing activities carried out by the former Nuclear Safety Management Construction area during the construction stage, taking the year 1977 as the beginning of regular inspection activities for this construction stage, and up to the year 1987, when this one is considered as practically completed, and a stage of pre-operational tests has been started. Finally, the main inspection areas are described, and a summary is given of the classification of deficiencies detected during the inspections

[en] This document describes the training of Laguna Verde Nuclear Power Plant Personnel, from recruitment and screening, through training to retraining to maintain the necessary skills and qualifications

[en] The work developed shows how the performance indicators are used with the objective of providing information of the trends and operational behavioural standards of the Laguna Verde NPP in a rapid and accessible way, so the this information could be useful to the personnel of the National Center of Nuclear Safety, in their tasks of identification and follow-up of the safe operational performance of the NPP, upon showing a reduction or an increase in the safe operation of the Laguna Verde NPP

[en] The Laguna Verde Nuclear Power Plant (LVNPP) is the first of its kind in Mexico. It is owned and operated by the Comision Federal de Electricidad (CFE), the National electric utility. Right now the plant is undergoing the start-up procedures and it reached 50% of power last September. In 1985 CFE received IAEA support to obtain a Fuel Management System (FMS) Computer Code Package from Scandpower Inc., and this paper presents the results of the calculation of the Nuclear Data Bank (NDB) and the simulation of the first cycle for the unit one of the LVNPP. The data have been tested and validated against the General Electric Cycle Management Report (GE-CMR). Results obtained using the FMS codes are compared to those obtained using GE codes.
