DEFINITIONS-

".

  • E REPORTABLE EVENT:

17 AL REPORTABLE-EVENT shall be_ one of those conditions specified in-

-Section 50.73 to 10 CFR Part 50.

CONTAINMENT'lNTEGRITY:-

1. _8 CONTAINMENT INTEGRITY shall exist when:

a.

. All penetrations required to be closed during accident conditions are.either:

1.=

Capable of being closed by an OPERABLE containment-automatic isolation system,- or 2.-

Closed by manual valves, blind flanges, or deactivated automatic valves secured _in their closed positions, cxcept those approved to be opened under administrative

controls, b.

All-equipment hatches are closed and sealed, c.

Each airlock is OPERABLE pursuant to Specification 3.6.1.3,

d.-

The containment leakage rates are within the limits of Specification 3.6.1.2, and e.

The sealing mechanism associated with each penetration (e.g.,

welds, bellows.or _0-rings) is OPERABLE.

CHANNEL CALIBRATlQH

'l.9 -

A CHANNEL CALIBRATION shall be the adjustment,'as necessary, of the channel output such that it responds with necessary range and

' accuracy. to known values of the parameter which-the. channel monitors.

TheJ CHANNEL _ CAllBRATION shall _.cncompass the entire channel including the sensor and alarm and/or trip functions, and shall include the CHANNEL FUNCTIONAL TEST, CHANNEL CAllBRATION may.be performed by any series of sequential, overlapping or total channel steps-such that the entire channel is calibrated.-

lr

- Calibration of instrument channels with ' resistance temperature L

g-detectors (RTD).or : thermocouple sensors shall_

consist - of u

-verification of functional capability of the sensing element, and normal calibration of the : remaining adjustable devices-in _ the

_g

. ggy channel.

Not

=$8 CHANNEL--CHECK mn

,? -

1.10 A CHANNEL-CHECK shall be the qualitative assessment of channel H.y behavior during operation by observation. This determination shall include, where possible, comparison of the channel indication and/or

-o

'R@.

status with other indications and/or status derived from independent

}j instrument channels measuring the same parameter.
