REPORTABLE EVENT 1.36 A REPORTABLE EVENT shall be any of those conditions specified in 10 CFR 50.73.
ROD DENSITY 1.37 ROD DENSITY shall be the number of control rod notches inserted as a
~ fraction of the total number of control rod notches.
All rods fully inserted is equivalent to 100K ROD DENSITY.
SECONDARY CONTAINMENT INTEGRITY 1.38 SECONDARY CONTAINMENT INTEGRITY shall exist;when:
a.
All reactor building ana auxiliary bay penetrations required to be closed during accident conditions are either:
1.
Capable of being closed by an OPERABLE reactor building automatic isolation system, or 2.
Closed by at least one manual valve, blind flange, or deactivated auto-matic valve or damper secured in its closed position, except as pro-vided in Table 3.6.5.2-1 of Specification 3.6.5.2.
b.
All auxiliary bay hatches are closed and sealed.
c.
The standby gas treatment system is in compliance with the requirements of Specification 3.6.5.3.
d.
At least one door in each access to the reactor building and auxiliary bays is closed except during normal entry and exit.
e.
The sealing mechanism associated with each reactor building and auxiliary bay penetration (e. g., welds, bellows, or 0-rings) is OPERABLE.
f.
The pressure within the reactor building and auxiliary bays is less han
