PLANT SYSTEMS BASE 5 SNUBBERS (Continued) 1 The service life of a snubber is. established via manufacturer input and information through consideration of the snubber service conditions and 4 associated installation and maintenance records (newly installed snubbers.. seal.  ;

replaced, spring replaced, in high radiation area, in high temperature area, etc.). The requirement to monitor the snubber service life is included to' l f

ensure that the snubbers periodically undergo a perforssace evaluation in view  !

of their age and operating conditions. These records will provide statistical .

bases for future consideration of snubber service life. t 3/4.7.9 SEALED SOURCE CONTAMINATION s

The limitations on removable contamination for sources reoviring leak '

testing, i ncluding alpha emitters, is based on 10 CFR 70.39(a)(3) limits for-plutonism.  !

This limitation will ensure that leakage from Byproduct, Source, and Special Nuclear Material sources will not exceed allowable intake values' ,

Sealed sources are c)assified into three gro es according to their use, l with Surveillance Requirements commensurate with the precability of damage to a i source in that group. Those sources which are frequently handled are required to be tested more often than thost. *tich are not. Sealed sources which are continuously enclosed within a su'oded mechanism (i.e., sealed sources within ..

radiation monitoring or baron measuring devices) are considered to be stored and need not.be tested unless they are removed from the shielded mechanism.  !

PROPOSED CHANGES TO THE FSAR Add to section 3.11.B.1 as item "D" prior to section 3.11.B.1.1 (Page 3.11.B.1-6)

D. Rooms with safety related equipment necessary for safe shutdown were evaluated to  !

assure that the temperatures would be within acceptable values in order to determine the necessity for temperature surveillance. Rooms that met any of the following criteria do not require surveillance:

. Rooms with safety related HVAC systems i

. Rooms with a high temperature alarm that annunciates in the main control room when the normal design temperature is exceededt

. Rooms classified as mild environment where the calculated room temperature with l a loss of normal HVAC for seven days is less than 150 F

. Rooms with natural ventilation and designed for ambient conditions (e.g. NSCW Pumphouse)

Rooms that contain safety related equipment necessary for safe shutdown that do not meet any of the above criteria were also evaluated based on historical records of temperatures.

These records indicated that the temperatures remain within their environmental qualification limits with the normally provided HVAC in operation, but that upcn failure of the HVAC it is possible for the room temperature to exceed the values assumed for ,

equipment environmental qualification. Therefore, surveillance of these rooms is conducted in accordance with section 16.3, Area Temperature Monitoring, in the event of a loss of the normal HVAC. -

The qualified life of environmentally qualified equipment is based on the emironmental conditions indicated in table 3.11.B.1-1. Area temperature monitoring in conjunction with the evaluation described above provides reasonable assurance that the normal temperature -

used for emironmental qualification of safety related equipment necessary for safe l shutdown is not exceeded without an evaluatien of equipment operability.

E4-1 l 1 IIigh temperature alanns require the samc level of action for exceeding the design temperature limits as those described in section 16.3, Area Temperature Monitoring.  !

REQUEST TO REVISE TECHNICAL SPECIFICATIONS l

RELATED TO AREA TEMPERATURE MONITORING PROPOSED CHANGES TO THE FSAR Add to FSAR Section 16.3 Requirement 7 - Area Temperature Monitoring The temperature limitatic for each areat specified in table 16.3-6 shall not be exceeded for more than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> and a maximum temperature of 150 F shall not be exceeded.

Whenever the above temperature limitations are exceeded, perform the following:

1. With one or more area (s) exceeding the temperature limit (s) shown in table 16.3-6 for more the 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, prepare an analysis within 30 days to determine the effect on  !

equipment operability and qualified life.  !

2. With one or more areas exceeding 150 F, within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> either:

. Restore the area (s) temperature to less than the limit (s) shown in table 16.3-6, and prepare an evaluation as stated in 1 above to demonstrate equipment operability, or  !

. Declare the equipment in the affected area (s) inoperable.

The temperature in each of the affected areas shown in table 16.3-6 shall be determined to be within its limit at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> when the associated area normal 2 IIVAC ,

system is not in service.

E4-2 [

l The basis for exclusion of areas from this table is given in section 3.11.B.I. .

2 For purposes of Area Temperature Monitoring, normal ventilation is defined as the following HVAC components or, the minimum amount of ventilation which can be shown, either through analysis or empirical data, to be sufficient to maintain the area temperature below the values shown in table 16.3-6.

A stable temperature must be achieved if using empirical data tojustify discontinuing or exempting an area from temperature monitoring.
