- 37 - there is no formal structure for the reports on certain checks (correct operation of the level measurement devices in the backup generator fuel storage tanks, visual check on areas containing backup batteries, etc.) (Golfech, Fessenheim); filling out of the operational documents and periodic test reports, the associated second level check, and the drafting of anomaly sheets if the results are unsatisfactory or satisfactory with reservations, is sometimes partial or insufficient (particularly at Civaux, Golfech). Equipment preventive maintenance During their examination of the basic preventive maintenance programmes (PBMP), the inspectors in particular observed that: certain PBMP updates, especially those under the responsibility of the head office departments, were produced belatedly (Golfech, Paluel, Penly, Saint-Alban); some new equipment, such as the OPzS batteries, is not at present covered by an appropriate maintenance programme (Fessenheim). The inspectors also observed that certain maintenance monitoring programmes were ineffective (EDF monitoring of the quality-related activities performed by contractors, in accordance with article 4 of the order of 10th August 1984). Cleanness of premises During the visits, the inspectors observed a remarkable lack of upkeep of some areas on the majority of the sites: cigarette butts were found at the bottom of a manhole in a fuel oil transfer area (Civaux); bird droppings, which could disrupt the operation of the electricity generating set air coolers, are still present owing to the postponed installation of bird defence systems on the roofs (Gravelines); several areas contain puddles of oil, fuel or coolant caused by seepage or small leaks (Civaux, Nogent, Paluel); a fuel pump leak tank was three-quarters full of a liquid that could not be identified on the day of the inspection (Nogent). 2.4.3 Backup electricity generating sets ASN finds that the periodic inspections and servicing of the backup electricity generating sets could be improved. Analysis of fluids To ensure that the backup electricity generating sets are in good working order, the quality of the fluids (oil, fuel and coolant) is periodically analysed by the licensee in accordance with the national preventive maintenance programmes. During the course of the spot-checks, the inspectors found that the quality of these analyses could be improved, in particular: the licensee does not consider these analyses to be a "quality-related activity" as defined in article 2 of the order of 10th August 1984; in this respect, it does not apply the resulting quality requirements to these activities, in particular the provisions of article 4 of the order of 10th August 1984 which stipulates appropriate monitoring (Cattenom, Fessenheim); in certain local preventive maintenance programmes as of the date of the inspection, no provision was made for periodic fluid analyses (Chooz); some of the analyses required by the PBMP (zinc and phosphate levels in the coolant fluid, fuel checks at delivery) may not be performed (Golfech, Paluel, Penly); in the analysis reports concerning, for example, the water content levels, there is a lack of precision; different measurement units from those of the PBMP were also used (Chinon, Dampierre, Gravelines, Paluel, Saint-Laurent);
