i 1.
The minimurn number of Cobalt strips meeting the scenario posed is one strip. The source strengths vary from 70 Ci to 1100 Cf. Treating the weakest source as a point and taking the distance to the door opening of 12 feet, D calc = 7 R/hr. This is consistent with repeated measurements using a 3-strip rack of activity 251 Ci which gave 50R/hr at 8 3/4 ft from the l
window. The meter used for cave entry monitoring is used on a low scale of 0-5 ll millirem /hr.
2.
See above.
The strips continue to provide useful radiation levels after 3 half-lives at Iowdl; no i
projection has been made regarding the end of useful life of the cobalt strips. his question win need to be revisited near the time of reactor license expiration in 2015.
3.
In the first 8 months of 1996, the radiation monitoring system was cheued on 69 days of 143 days available for reactor operation. At the time of system checkout on 13 of those days, the gamma cave was in use and that portion of the system could not be tested since entry to the i
1 access corridor was prohibited. The contact Q1 is a normally closed relay contact in the l
Radiation Monitoring System module (Tracerlab TA-30 Station Indicator) which is held open by bypass current flowing through a parallel gated SCR. Removal of power or failure of components on the module results in Q1 closing and initiating the warnings and alarms as j
though a high radiation level were detected. Once the contact has closed, manual action is required for reset.
4.
The in-cave detector and the in-cave cable ends failed from a combination of high radiation levels and damp environment. The in-cave system has not functioned at any time in the memory of present staff members.
S, The bell warning of cobalt source move can be heard clearly in the Gamma Cave.
6-In order to answer the question in detail, the wiring would have to be disassembled.
Functional tests show that the red light is activated when the in-cave alert switch is thrown.
7.
The radiation survey meter is held a8ainst a check source fastened to the wall to the left of the cave door prior to unlocking the door.

TO 13014152260 P.05 taken to prevent furthe-contamination. If the gross activity of the sample is less than 1 x 10-7 micro Ci per m1, specific analysis for Co-60 need not be performed. These analyses have been performed since 1982. An analysis of sample tesults for the past two years showed tlutt detectable levels of Co-60 are absent when the reactor does not operate at significant megawatt-day levels. Co 60 is only occasionally detectable as a result of reactor operation and has not exceeded 1.5 E-8 micro Ci/ml in the past two years.
