APPENDIX A NOTICE OF DEVIATION Pennsylvania Power and Light Company Docket Nos. 50-387 Susquehanna Steam Electric Station 50-388 Allentown, Pennsylvania 18101 License Nos. CPPR-101 CPPR-102 l
As a result of the inspection conducted on May 12-16, 1986, and in accordance 1
with the NRC Enforcement Policy (10 CFR 2, Appendix C), as revised, 49 CFR 8583 (March 8,1984), the following deviation was identified:
The FSAR Section 2.3.3 states that the instrument accuracy for the primary meteorological monitors will be the following:
- wind speed 1% of full scale or 10.15 mph;
- wind direction 2 based on 540 range; and,
- delta temperature 10.15 /50m.
Contrary to the above, the measurement accuracy for wind speed, wind direction and an estimate of atmospheric stability are not adhered to in the meteorological monitoring program in that the calibration procedures used for these instruments, SI-099-313 to SI-099-318, have the following tolerance limits:
- wind speed 15.6/ 2.8 mph
- wind direction 19.4/ 9.7 degrees
- delta temperature 1.6/ 0.8 F (10.9/ 0.44 C) for the "as found" and "as left" accuracy specifications, respectively.
Further, the calibration procedure for delta-temperature instrumentation doesn't include an actual sensor calibration (i.e., water bath to test accuracy of thermistor). Only, an electronics loop calibration is per-formed, which assumes no instrument measurement error.
Pursuant to the provisions of 10 CFR 2.201, Pennsylvania Power and Light Company is hereby required to submit to this office within thirty days of the date of the letter which transmitted this Notice, a written statement or explanation in reply, including: (1) the corrective steps which have been taken and the results achieved; (2) corrective steps which will be taken to avoid further deviations; and (3) the date when corrective action will be completed.

i APPENDIX B APPRAISAL UNRESOLVED ITEMS 1.-
UNRESOLVED ITEM 50-387/86-10-10, 50-388/86-10 Provide a specific proceduralized plan for performing frequent radiological surveys of as-sembly areas to ensure habitability. The Radiation Protection Coordinator should be assigned the responsibility for providing monitoring of the as-sembly areas.
At least a minimum amount of radiological monitoring equipment should be stored at each of the assembly areas to ensure that personnel would not have to travel from the OSC to the TSC without survey equipment.
Formally address the potential need for having backup locations for the assembly areas in the event that one or all of these areas become uninhabitable due to high radiation.
2.
UNRESOLVED ITEM 50-387/86-10-11, 50-388/86-10 Provide dosimeters to all personnel in the assembly areas and routinely have the individuals read their dosimeters.
Record and track dose of all assembly area personnel.
3.
UNRESOLVED ITEM 50-387/86-10-12, 50-388/86-10 Protective supplies (protective clothing and respiratory protection) should be stored in the assembly areas to assure OSC staff are adequately protected from radio-logical hazards while traveling from the OSC to the TSC and into the plant. Planning for alternate assembly location should also include stores of protective equipment.

APPENDIX C APPRAISAL OPEN ITEMS 1.
A full description of the meteorological monitoring program is needed including details on additional information that may be requested from the National Weather Service (50-387/86-10-01, 50-388/86-10-01).
2.
TSC does not appear to have any source of emergency lighting during a station blackout (50-387/86-10-02, 50-388/86-10-02).
3.
Cabling, phone, and power cords in the TSC are subject to mechanical damage during movement of personnel or equipment (50-387/86-10-03, 50-388/86-10-03).
4.
Emergency procedures should address any serious degradation of Emergency Response Facilities (50-387/86-10-04, 50-388/86-10-04).
5.
Dose assessment of discrete puff-type releases needs review and clarification (50-387/86-10-05, 50-388/86-10-05).
6.
Clarification is needed of how PP&L engineering personnel specify compression limit ranges for plant computer values (50-387/86-10-06, 50-388/86-10-06).
7.
Delta-temperature meteorological instrument sensors are not properly calibrated (50-387/86-10-08, 50-388/86-10-08).
8.
Diverse OSC assembly areas need to be addressed in the Emergency Plan and Procedures (50-387/86-10-09, 50-388/86-10-09).
9.
Emergency Plan should be changed to correctly reflect the location of equipment and supplies available for use during an emergency (50-387/86-10-13,50-388/86-10-13).
- 10. The licensee needs to formalize minimum staffing standards for the 4
Operational Support Center (50-387/86-10-14, 50-388/86-10-14).
- 11. Correct temporary electrical and phone wiring and cabling in the E0F (50-387/86-10-15,50-388/86-10-15).
