3.3 The second measurement<br />
campaign<br />
All measurements were performed with the fork<br />
prongs attached. Like in the first campaign, the<br />
horizontal coordinate x = 0 mm was used in all<br />
measurements<br />
The total neutron count, the gross gamma<br />
current and the gamma spectrum of assemblies<br />
no. 17–27 listed in Table I were measured at three<br />
different heights, at z = 5135, 5705 and 6275. Like<br />
in the September campaign, the assemblies were<br />
measured at four sides with 90 degrees rotation.<br />
The assembly #12323, which had been measured<br />
in September, was remeasured to scale the measurement<br />
data of this campaign with the September<br />
campaign.<br />
The fuel assembly #12323 was scanned axially<br />
at eleven vertical positions (Table III).<br />
