INTRODUCTION This submittal complies with the format described in Regulatory Guide 1.21, "Measuring, Evaluating and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water Cooled Nuclear Power Plants", Revision 1, June, 1974 with data summarized on a quarterly basis following the format of Appendix B thereof.
In accordance with LGS Technical Specification 6.9.1.8, this document summarizes the gaseous effluent releases for the period of July 1, 1987 through December 31, 1987 and the resultant doses from both pathways to members of the public for the period January 1, 1987 through December 31, 1987.
Where "0.00E+00" is used, it denotes the less than detectable level for the given isotope.
Supplemental information, consistent with the format of Appendix B of Regulatory Guide 1.21, is also included.
A summary of the meteorological measurements taken during the third and fourth quarters of 1987 is submitted as joint frequency distributions of wind direction and wind speed by atmospheric stability class.
Disposition of solid waste during the report period (July 1, 1987 to December 30, 1987) is described within to include: the total activity shipped by waste type and an estimate of the error in the reported totals; the estimated composition of each type of waste by isotope; and the solid waste disposition, i.e. number of shipments, mode of transportation, destination, type of container, total container volume, and solidification agent.
Pursuant to Technical Specification 3.3.7.11, an explanation of why inoperable Residual Heat Removal Service Water Radiation Monitors (A, B, and C) were not returned to service within the time specified.
There were no changes to the Offsite Dose Calculation Manual (ODCM) or Process Control Program (PCP) during the report period.
There were no major changes to Radioactive Waste Treatment Systems during the report period.

Meteorological Measurements - Joint Frequency Tables The joint frequency distributions of wind direction and speed, by atmospheric stability class are attached under separate cover.
The distributions include all three wind levels from Limerick Meteorological Tower No.
1.
The distributions were developed on the Radiation and Meteorological Monitoring System -
RM-21A system.
Each of these "wind roses" consists of eight pages of joint frequency distributions.
There is one distribution for each of the seven Pasquill-Gifford stability classes, A through G, and a combined "All Classes" page.
The Pasquill-Gifford stability classes are determined by the temperature differences measured over the 266-26 feet and the 171-26 feet height intervals.
All meteorological data were finalized on the RM-21A system.
NRC format meteorological data tapes covering the periods January 1987 through June 1987 and July 1987 through December 1987 are currently retained on site.

Radiation Doses to Members of the Public Due to Their Activities Inside Site Boundary Per Technical Specification 6.9.1.8, the Semi-Annual Effluent Release Report shall iriclude an assessment of the radiation doses from radioactive liquid and gaseous effluents to members of the public due to their activities inside the site boundary during the report period.
Technical Specifications state that members of the public shall include all persons who are not occupationally associated with the plant.
This category does not include employees of the utility, its contractors, or vendors.
Also excluded from this category are persons who enter the site to service equipment or to make deliveries.
This category does include persons who use portions of the site for recreational, occupational, or other purposes not associated with the plant.
The maximum gaseous dose to members of the public as defined i
above is less than 1.0E-4 mrem and is based on the following assumptions:
a 1.
Real time meteorology and gaseous effluent releases.
2.
Total body dose due to an inhalation exposure.
\\
l 3.
Highest exposed sector (SW) of those sectors within site boundary available for occupancy.
4 4.
The maximum expected occupancy factor is a working year
[
(or 25%) along the railroad tracks.
5.
Distance to the railroad tracks, which pass through site boundary in the SW sector, is approximately 300 meters.

RESIDUAL HEAT REMOVAL (RHR) SERVICE WATER RADIATION MONITOR FAILURES During normal operations, the "A" and "B" RHR Service Water R; diction Monitors'were declared out-of-service due to indications of low sample flow.
An investigation of the problem rovoalad the accumulation of corrosive materials on the walls of
'tha piping.
Several factors were attributed to the corrosion:
a.
small diameter (l") pipe; b.
short pipe lengths; c,
numerous 90 degree elbows; 15.
river water, which is highly aggressive to carbon steel, i
is used to supply service water.
Th2 incorporation of new pipe material (from carbon steel to Dtoinless steel) and reduced bendings in the pipe lines (to fccilitate system flushing) was evaluated as the long-term Solutions to redeposition of corrosive products in the RHR 3Orvica Water Radiation Monitor sample lines.
The thirty (30) i 90y action described in Technical Specification Table 4.3.7.11-lb Dction 101 was exceeded because the corrective maintenance of ecplccing sample piping could not physically be performed'in the 31n3 cpecified while observing all applicable station Ddainistrative controls.
At the present time, the "A" and "C" radiation monitors are ut-of-service.
The Technical Specification requirement to take rab etmples every eight hours has been observed during the
.ntire period of RHR Service Water Radiation Monitor 6nop3rcbility.
Replacement of all RHR Service Water sample lines 6c cch^duled during the second quarter of 1988.
