The “COMPARISON OF RO’94 / RO’96 / RO’97<br />
/ RO’99 DATA” table demonstrates how the process<br />
has notably improved over the last few years.<br />
OTHER EVENTS<br />
Two especially relevant events occurred during<br />
the year:<br />
The first was renewal of the plant’s Operating<br />
License for a period of 10 years. This has culminated<br />
an extensive plant safety and reliability review effort,<br />
in which many people from Nuclenor and other<br />
firms have taken part, and I would like to thank them<br />
for their dedication and professionalism. It has also<br />
meant that the institutions involved have placed<br />
their trust in Nuclenor, and we hope not to betray<br />
that trust.<br />
The second event was the announcement by the<br />
Spanish Socialist Party on the verge of the general<br />
elections that it is against nuclear power. In the<br />
event that this party wins the elections, Santa María<br />
Garoña is threatened with closure in the year 2000,<br />
along with José Cabrera NPP. This emergence of<br />
political motivations has caused distractions in the<br />
work climate of affected personnel and will<br />
continue to do so whatever the result of the<br />
forthcoming elections may be.<br />
TRAINING<br />
Just as in previous years, and very particularly the<br />
preceding year, the staff training activities have<br />
continued and have occupied a significant portion<br />
of working hours. General, specific and simulator<br />
training has been provided.<br />

OTROS ACONTECIMIENTOS<br />
En el año se han producido dos<br />
hechos especial relevancia:<br />
El primero de ellos ha sido la renovación<br />
del Permiso de<br />
Explotación de la central por un periodo<br />
de 10 años. Esto ha culminado<br />
un esfuerzo muy notable de revisión<br />
de la seguridad y fiabilidad<br />
de la central en el cual han anticipado<br />
muchas personas de Nuclenor<br />
y de otras empresas a las que quiero<br />
agradecer su dedicación y profesionalidad.<br />
Ha supuesto también<br />

SOCIAL COMMUNICATION<br />
The efforts to communicate and inform on our<br />
activity have continued. During 1999, 457 groups<br />
containing a total of 19,184 people visited the<br />
Information Center. Most of the visitors (65%) were<br />
from educational centers, mostly young people<br />
between the ages of 16-18 years. 52% of the visits<br />
were from the Castilla y Leon region.<br />
A total of 143,220 people have visited the<br />
Information Center since it was opened.<br />
The INFO brochure is still being published; 6<br />
issues have been published, with a total of 85,000<br />
copies.<br />
