The primary containment shall be pneumatically pressurized in accordance with the schedule illustrated in Attachment A. The structural response of the primary containment as evidenced by concrete strain, embedded structural steel.

and liner strain, shell dimensicnal changes and the changes in surface concrete crack patterns shall be recorded at various pressure levels as specified herein.

Should the test, pressure drop due to an unexpected occurrence, the test director or his alternates shall Qo decide whether or not the test shall continue without a restart at atmospheric pressure.

.0 SCHEDULE The structural integrity test shall be conducted in

. accordance with established construction and start-up schedules. The test should not be scheduled to be conducted during a period when extreme inclement weather conditions, for example, snow, heavy rain, or strong wind are forecast. Should these conditions occur during the test despite the forecast, the test results will be considered valid unless there is evidence to indicate otherwise. However, the test shall not he'conducted under ambient. weather conditions which. prevent or impair conduct of the specified inspections of the containment exterior surface.

~ .0 5 The primary containment shall be structurally ccmplete prior, to the start of the structural integrity test. The reactor vessel, reactor shield and internal framing, need not be complete. All primary containment concrete shall have reached design strength.

b. During subsequent crack surveys, the procedure described in Section 7.3.2, part (a) shall he followed with the modification noted below:

Cracks existing at a preceding stage may'increase or'decrease in length and/or width. 'Xhe width of an existing crack shall be measured and recorded per the specimen data sheet at the point where the previous measurement was made. The width of a new crack or an existing crack which has widened to .01 in. shall be measured at what is judged to be the widest point along the length of. crack line within the gridded area. ,The new crack shall be marked per Section 7. 3. 2, part (a}, step 1, if the measured width exceeds .01 in. Length increases shall be marked as in Section 7.3.2, part (a},

step 1, by extending the existing lumber crayon line and noting the new end point by a short cross line. Crack shortening shall be noted only 'if the portion of the crack becomes totally invisible to the naked eye.
