Abstract

ABSTRACT
EFFECT OF CHLORIDE ION AND COPPER ION FOR TANK MATERIAL INTEGRITY OF
RSG GAS PRIMARY COOLING SYSTEM. RSG GAS as Multipurpose Reactor designed to
operate for 30 years, now RSG GAS has been operating for approximately 29 years. Al2Mg3
as a reactor tank material has a weakness in its use, that is not resistant for environment that
contains of chloride ions and copper ion. The purpose of this research was to know the
impact of Cl- and Cu2+for tank material integrity of the RSG GAS primary cooling system. The
analysis is done by simulation on Al2Mg3 corrosion in Cl- and Cu2+ solution using
Potensiogalvanostate IG & G. The results showed that the concentration of chloride ion in
the primary cooling water that greater than 6 ppm have potentially to degrade the integrity of
reactor tank material. The existence of copper ions in the primary cooling water will
accelerate the damage to the reactor tank. Material integrity of RSG GAS reactor tank can
be maintained by limiting the concentration of chloride and copper ions in each of the
primary cooling water in accordance with the standard requirement.
Keywords: integrity, the reactor tank material, the primary cooling water, RSG-GAS.
ABSTRAK
PENGARUH ION KLORIDA DAN ION TEMBAGA TERHADAP INTEGRITAS MATERIAL
TANGKI PADA SISTEM PENDINGIN PRIMER REAKTOR RSG GAS. Reaktor Serba Guna
G.A. Siwabessy (RSG GAS) dirancang untuk beroperasi selama 30 tahun, sampai saat ini
RSG GAS telah beroperasi selama kurang-lebih 29 tahun. Al2Mg3 sebagai bahan tangki
reaktor mempunyai kelemahan dalam penggunaannya yaitu tidak tahan dengan lingkungan
yang mengandung ion klorida Cl- dan ion tembaga Cu2+. Penelitian ini bertujuan untuk
mengetahui pengaruh Cl- dan Cu2+ terhadap integritas tangki Reaktor RSG GAS. Analisis
dilakukan melalui simulasi uji korosi Al2Mg3 dalam lingkungan ion Cl- dan Cu2+ menggunakan
Potensiogalvanostate IG&G. Hasil penelitian menunjukkan bahwa pada konsentrasi ion
klorida dalam ATR lebih besar dari 6 ppm berpotensi mendegradasi integritas tangki reaktor.
Keberadaan ion tembaga dalam ATR akan mempercepat kerusakan tangki reaktor.
Integritas tangki reaktor RSG GAS dapat dipertahankan dengan membatasi konsentrasi ion
klorida dan ion tembaga dalam air pendingin primer masing-masing tidak melebihi standar
yang dipersyaratkan.
Kata Kunci : integritas, tangki reaktor, air pendingin primer, RSG-GAS.
