Pakar Reaktor Nuklir Indonesia (Bagian-4)

NAMA Liem Peng Hong (LPH) dipastikan keturunan Tionghoa. Lulus S1 pada 1985 dari UGM di bidang nuclear engineering dengan predikat cum laude, lulus S2 (1990) dan S3 (1993) dari Tokyo Institute of Technology juga di bidang nuclear engineering. Sebelum memasuki studi S1, Liem harus belajar bahasa Jepang di Osaka University of Foreign Studies, Japanese Language Special Course, Osaka, Jepang pada 1987.

Liem merupakan seorang ilmuwan tulen tentang reaktor nuklir bidang nuclear engineering yang dia tekuni sejak program S1 sampai S3. Liem juga mengajar dan atau tenaga peneliti di berbagai universitas baik di Jepang dan Indonesia. Yang penting dicatat ialah saat program S3, supervisornya adalah Prof Dr Hiroshi Sekimoto, salah satu ilmuwan nuklir terkenal di dunia. Karena itu saat Bill Gates (seorang konglomerat dunia yang masuk 5 besar) mendesain TWR (travelling wave reactor), dia membentuk tim ahli dan merekrut  ahli nuklir nomor wahid dari seluruh dunia, dan salah satunya adalah Sekimoto. Jika awalnya Sekimoto adalah guru dari Liem, dalam perkembangannya dia menjadi rekan dalam berbagai tulisan ilmiah yang bergengsi. (https://www.researchgate.net/profile/Liem-Hong ).

Dari berbagai karya tersebut di atas, harus diakui bahwa Liem yang hobinya robotics, adalah seorang ilmuwan tulen. Dia diakui dunia internasional karena kepakarannya sehingga diundang berbicara pada berbagai forum internasional baik konferensi maupun bentuk pertemuan ilmiah lainnya. Liem telah membuktikan dirinya seorang nasionalis sejati yang telah mengharumkan nama Indonesia di dunia internasional melalui karya-karya ilmiahnya. 

Semoga dengan tulisan ini banyak pihak bisa lebih mengenal Liem, baik pemerintah maupun pengusaha untuk kemudian mengikut sertakan Liem secara aktif dalam persiapan Indonesia membangun PLTN secara riil mulai saat ini. Karena tuntutan obyektif untuk menggantikan peran dari bahan bakar fosil khusus batu bara yang perannya akan berakhir pada 2040, menuju net zero emission pada 2050. 

Peran batu bara ini akan berakhir pada 2040 sebagaimana ditegaskan Presiden Jokowi kepada PM Inggris Boris Johnson saat percakapan mereka pada 29 Oktober 2021, mengawali kehadiran Presiden di UN Climate Change Conference (COP26) di Glasgow, UK, 1-2 Nopember 2021.

Saat ini Liem bekerja sebagai peneliti dan kepala kelompok di NAIS (Nippon Advanced Information Service) yang kantornya di desa Tokai-mura, Ibaraki, Jepang. Peran NAIS dan Liem secara umum dapat dijelaskan dengan singkat yaitu melakukan kontrak-kontrak komersial kegiatan litbang dari lembaga-lembaga pemerintah berkaitan dengan nuklir (seperti JAEA (Japan Atomic Energy Agency), NRA (Nuclear Regulatory Authority), institusi litbang, universitas negeri dan swasta, perusahaan listrik swasta, perusahaan swasta lainnya, melakukan bisnis sebagai vendor, supply chain atau service di bidang nuklir. 

Tema kontrak-kontrak komersial sangat beragam mulai dari perancangan dan analisis, sampai evaluasi keselamatan reaktor riset, perangkat kritis, PLTN air, HTGR, Fast Reactor, MSR, ADS (accelerator driven system), fasilitas iradiasi (medis dan non-medis), khusus untuk tragedi kecelakaan Fukushima Dai-Ichi, NAIS secara khusus memberikan pelayanan analisis dan pengembangan metode maupun perangkat lunak untuk mengetahui bagaimana penyebaran bahan-bahan radiokatif yang dilepaskan selama dan setelah kecelakaan ke lingkungan. 

Selain itu NAIS juga membantu mengembangkan pemodelan dan perangkat  lunak untuk decommissioning instalasi nuklir yang mengalami kecelakaan seperti Fukushima. Tujuannya agar meminimalkan biaya, paparan radiasi pekerja serta risiko kontaminasi lingkungan.
