- 11) A gross radioactivity analysi s shall consist of the quantitative measurement i
of the total radioactivity of the primary coolant in units of pCi/gm.
~1 h e i
. total primary coolant activity shall be the su.n of the Jegassed beta-gamma j
activity and the total of al1 identific d gaseous activities 15 minutes aft er the primary system is sampled.
Whenever the grons radioactivity concentratien exceeds 10'. of the limit specified in the Specification v
3.1.4.1 or increases by 10 pCi/gm from the previous measured level, the frequency of sampiing and analyzing sh 11 be increased to a mir.imum of once/ day until a steady activity level is established.
