TABLE NOTATION b-The principal gamma emitters for which the'LLD specification applies exclusivily are~the following radionuclides:

Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, and Xe-138 for gaseous emissions and Mn-54, Fe-59,.

l Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Co-141 and Ce-144 for particulate emissions. This list does not mean that only these nuclides l

are to be considered. Other gamma peaks that are identifiable, together-with those of the above nuclides, shall also be analyzed and reported in the Annual Radioactive Effluent Release Report pursuant to Specification l

6.9.1.8.

d-Tritium grab samples shall be taken at least once per 7 days from the ventilation exhaust from the spent fuel pool area, whenever spent fuel is in the spent fuel pool.

e-The ratio of the sample flow rate to the sampled stream flow rate shall

be known for the time period covered by each dose or dose rate calculation made in accordance with Specifications 3.11.2.1, 3.11.2.2 and 3.11.2.3.

This requirement does not apply if (1) analysis shows that the DOSE EQUIVALENT I-131 concentration in the primary coolant has not increased more than a factor of 3; and (2) the condenser offgas noble gas monitor shows that offgas activity has not increased more than a factor of 3.
